Wyoming Will Become a Premier Global Supplier of Helium Via Blue Spruce Operating’s Dry Piney Helium Plant in Sublette County


     With helium supply currently constrained by the Strait of Hormuz disruption and damage at Qatari LNG gas processing facilities, which are a major source of helium, there is a clear need for alternative supply both in the near term and for the long term.

     Blue Spruce Operating is developing the Dry Piney Helium Plant in Sublette County. Construction was set to begin in May 2026. The $1.3 billion project is expected to bring Wyoming’s contribution to 30% of global helium production. Construction is expected to be modular, with large modular components delivered to the site. According to Blue Spruce cofounder Andrew Moses:

“We’ve designed the gas processing facility so we can basically haul in big modules and hook them up in the field,” Moses said. “Rather than doing all of the construction and fabrication on site.”

     To minimize wildlife impacts, the project is sticking to a limited 5.5-month construction window per year from May 1 through November 15.

     When the plant is operational, it will advance Wyoming’s global contribution to helium production from 20% currently to 30%. Thus, this project alone represents 10% of global helium production. The project is very close to ExxonMobil’s LaBarge-Shute Creek facility, which produces around 20% of the world’s supply. Along with ExxonMobil’s project, it produces from the La Barge Platform.

“They are on the La Barge platform, which is this big, buried structure that allowed gases to accumulate for probably close to 70 million years,” Center for Economic Geology Research Director Fred McLaughlin told Cowboy State Daily in a previous interview. “And that’s one of the secrets to getting helium to slowly build up, because helium is a small atom, and it’s super buoyant and slippery.”

     The La Barge Platform is located at the edge of the Green River Basin and offers a very good helium trapping mechanism. The new project is also expected to produce about 1 TCF of natural gas over its lifetime.






     The Japan Petroleum Exploration Company (JAPEX) is a partner in the project.

“They’ve been a great strategic partner and have really helped us get to the point where we are at, ready to begin construction on May 1,” Moses said.

     Moses also notes that the state and county will benefit from the significant tax revenue.

“We will be generating over $20 million per year in severance taxes to the state of Wyoming,” Moses said. “And over $20 million a year in ad valorem taxes to Sublette County, where the project is located.”

“Over a 50-year project lifespan, that’s close to $2 billion in combined tax revenues, Moses said. There will also be about $300 million in helium royalties sent to the Wyoming Office of State Lands and Investments.

     According to the Bureau of Land Management (BLM):

“The project is estimated to be capable of producing more than 800 million cubic feet of bulk liquid helium per year from subsurface mineral estates.”

“With this approval, Blue Spruce Operating, LLC, may construct a natural gas plant to process and separate raw gas streams into saleable helium and methane products. The project includes nine gas production wells, access roads, buried gathering and utility lines, a natural gas residue sales pipeline, and an acid-gas injection facility to permanently sequester excess carbon in federal pore space deep underground. Commercial operations are expected to begin during the summer of 2028.”

Non-Operated Working Interest Owners Provide Needed Quick Capital for Drilling and Production Projects: How It Works and The Future


 

      Non-operated working interest owners have long been a feature of oil & gas projects and companies. With the advent of shale and tight rock production, which is more repeatable and predictable than conventional exploration and production, non-op WI owners could be more confident that their investments would succeed. This is simply because the dry-hole risk is virtually non-existent in these resource plays.

     Mercer Capital explains non-op WI ownership as follows:

“A working interest is an interest in an oil and gas lease, entitling the owner to a percentage of the profits from the oil and gas extracted within a leasehold area. Working interests bear all costs corresponding to the amount of working interest held. For this reason, they are often considered to be like a net profit interest.”

     A non-operated working interest simply means that a working interest owner is not the operator of the well. They are an investor and do not typically make any decisions regarding the wells. When operators buy other companies or production, they often take on the non-op WI owners of that production. Companies also market and sell non-op interest to buyers to help finance their projects. Some companies like Northern Oil & Gas are aggregators on non-op WI.

     Below, Mercer Capital notes that the Council of Petroleum Accountants Societies (COPAS) provides guidance for joint operating agreements (JOAs) involving non-op WI owners.

“In some instances, owners of non-operating working interests are charged periodically to pay for their share of the overhead costs incurred by the operator. The rate at which this overhead is charged to the non-op interest owners will inevitably differ from actual overhead costs, which are partially variable. One organization that often plays a role in these contractual relationships between operators and non-operators is the Council of Petroleum Accountants Societies (“COPAS”). Though it has no statutory authority, the organization is influential in modeling standard and widely adopted accounting practices for developing and maintaining joint operating agreements between parties involved in the oil and gas industry. These practices include guidance on how operator costs and overhead are allocated between an operator and a non-op holder.”

     They give an example below of how operator profit and loss can affect non-op WI owners subject to fixed monthly costs. These capital obligations can result in losses when commodity prices are low, and the non-op WI owner is still obligated to pay for drilling and production expenses.




     As noted below in Part 2 of Mercer Capital’s analysis, non-op investors don’t have the same concerns as operators and can focus mainly on the profitability of their investments.

“Non-op interests can also provide capital to the industry that is needed for further development.  Investors in the non-op space tend to be economically rational.  Profit margins and cash flow returns are typically the more immediate motive as opposed to numerous other factors that can come into play for an operator, such as leases on future acreage, drilling plans, capital budgets, debt lending parameters, and other factors.”

     They note that there are both non-op funds which function much like royalty investors as well as a few publicly traded companies that focus exclusively on non-operated working interest.

“There is a growing trend within the oil and gas space of developing specific non-op funds to fill an important role in the upstream capital markets.  There is an interesting cross-section of E&P investors and more passive investors akin to royalty investors who have shown interest in the niche.”

“There are also a few (mostly small) publicly traded companies whereby non-operating working interests are a primary focus of their balance sheets.”





     Below, they compare public non-ops to public royalty investors, noting that these royalty aggregators typically trade at higher valuations than public non-ops.




“When done right, non-ops can provide superior returns and quality valuations.  When not done right, non-ops can (in some cases) be a source of negative cash flow and sub-par valuations.”

     Below, Ranger Land & Minerals compares royalty interest (RI), overriding royalty interest (ORRI), and operating working interest (OWI). Non-operating working interest (NOWI) is the fourth type of interest.




     Below, they give the benefits and risks of non-operated working interest investment.






     They note that due diligence is required, including the consideration of commodity pricing, geology, well and play profitability, cost structure, and well performance. They note that JOAs involve allocation of revenues and costs, decision-making authority of the operator, accounting and reporting procedures, rights of audit and inspection for non-operators, and dispute resolution mechanisms. There are also tax benefits to non-op investing. These include deduction of intangible drilling costs, tangible equipment depreciation, and depletion allowance. These factors can increase investor profitability.

     Below, they compare non-op WI investment to other types of energy investments.




     They summarize below what makes a successful strategy for non-op WI ownership:

“A successful strategy for non operated working interests requires careful due diligence, diversification, strong operator selection, and ongoing monitoring. By aligning with trustworthy partners, leveraging technological advancements, and planning for long-term cycles, investors can unlock meaningful returns while navigating the complexities of the energy market.”

 

Non-Operated Working Interest Portfolio Sales and M&A Potential

     There is a trend in recent times of non-op WI owners selling their portfolios to operators or to other companies focused on non-op WI. One recent example is Chord Energy, which just sold its portfolio of Marcellus non-op WI to South Korea’s Posco International for $550 million. Chord can now focus more exclusively on its oil-weighted portfolio in the Williston Basin. Its CEO, Danny Brown, noted:

“This highly accretive transaction allows us to further strengthen our peer-leading balance sheet and focus on creating significant value from our world-class Williston Basin position. Chord's disciplined capital allocation, operational efficiency, and financial strength position us to create value while navigating a volatile macro environment.”

     Another example is Northern Oil & Gas’s purchase of a 25% undivided stake in Canadian Duverney light oil assets with a long-term joint development agreement with Parallax Energy Operating, Inc.

     NOG’s management commented:

"Quality oil inventory is becoming increasingly scarce, and NOG's scaled non-operated model positions us to access opportunities that most in our sector cannot. Our ability to structure creative, accretive transactions with best-in-class operators is what sets NOG apart. The Duvernay is one of North America's premier light oil resources — high-quality, low-cost, long-life inventory with meaningful upside that remains largely untapped. Parallax is led by a team with a demonstrated track record of developing Duvernay assets, backed by Carnelian Energy Capital, one of North America’s leading energy investors. The decision to incorporate equity consideration aligns mutual interests while enhancing our per-share metrics and balance sheet. This transaction is the result of disciplined evaluation of the meaningful opportunities we see in Canada, and a direct reflection of our ability to identify and convert high-quality assets into long-term value for shareholders."

     It has also been suggested that public non-ops may become merger and acquisition (M&A) targets, especially when economics may be most favorable due to commodity prices.

Two Studies Suggest That Carbon Storage Through Enhanced Rock Weathering is Less Durable Than Thought


 

    Two recent studies cast doubt on the carbon removal durability of enhanced rock weathering.

 

Study 1: ‘Critical zone processes limit alkalinity export from natural basaltic systems’

     The first study was published in the journal Nature by researchers from Cornell University. The weathering of basalt, a volcanic rock, was studied in volcanic regions where it outcrops.

     According to the Cornell Chronicle:

“The researchers found that chemical reactions and limited water movement can substantially reduce the amount of weathering-generated alkalinity that leaves soils, moves through rivers and, ultimately, reaches the ocean. That alkalinity helps convert carbon dioxide into forms that can remain stored for long periods.”

     The conclusion of the study is simply that less carbon can be stored via enhanced weathering than previously thought.

“You obviously can buffer some CO2 emissions with this kind of process, but much less than people have hoped,” said lead author Louis Derry, professor in the Department of Earth and Atmospheric Sciences in the Cornell Duffield College of Engineering. “The idea that we’re going to get gigaton levels of CO2 reduction is not going to happen.”

     The researchers show that current methods of estimating the carbon removal effectiveness of enhanced weathering involve the dissolving and disappearance of calcium, magnesium, and other elements from crushed basalt in the upper 10 to 30 centimeters of soil. This is known as base cation depletion in the upper soil.  However, they argue that this is only the first step in the chemical process. As those chemical products pass through streams, soil, and groundwater, they enter the “critical zone,” the reactive layer where rock, soil, water, air, and living organisms interact. As the dissolved minerals move down, they can react with newly formed clays, oxides, and carbonate minerals, which can capture calcium and magnesium or generate acidity that consumes some of the alkalinity created by weathering.

“The net result is that only a modest fraction of dissolution products of weathering reactions – natural or engineered – is actually exported through the critical zone,” Derry said.




     They also challenge the assumption that grinding basalt into smaller particle sizes would enhance the speed of weathering reactions, noting that there is not a strong relationship between smaller particles and more surface area for reactions. I admit I am confused by this. I thought that anything broken into smaller pieces leads to more surface area being exposed. They do note a relationship between particle size and surface area at very fine sizes, however.  

“Among basalt samples proposed or used for enhanced weathering, the paper found no notable correlation between grain size and measured surface area.”

     They also note that enhanced weathering does work faster in wet, tropical environments, but not very fast in the dry, temperate areas that make up the world’s agricultural regions where most enhanced weathering projects have been proposed.

“Enhanced weathering may still provide useful local benefits, including buffering soil acidity, supplying nutrients or modestly offsetting emissions in some settings. But Derry argues that with limited resources available to address climate change, expectations for its global carbon-removal role should be grounded in how real landscapes behave.”

“We’ve got a lot of data from natural systems across a range of conditions,” Derry said. “We consistently see values that are much, much lower than the model studies. If you have finite resources to address a problem, you want to put them where they’re most likely to make a difference.”




     The study provides a good baseline for basaltic weathering. About 6% of the world’s surface is composed of basaltic rocks. Knowing the chemical weathering rates and characteristics of these zones provides important analysis for estimating the effectiveness of  enhanced weathering projects. They describe the findings as “limitations on watershed alkalinity export.” There are two kinds of limitations: 1) the formation of secondary minerals that react with dissolved mineral products in the critical zone, and 2) hydrological limitations where river basin discharge rates may not be enough to export more of the alkalinity.






Study 2: ‘Can enhanced alkalinity store carbon durably? Key questions remain about carbon removal strategies in open environmental systems’

     The second study has similar conclusions to the first, that enhanced weathering is not as durable as previously thought. Similarly, it is noted that reactions in the soil capture and utilize some of the carbon, break it down, and it makes its way to the atmosphere before it gets to the ocean or becomes sequestered underground for a lesser time period.




     According to an article about the study in The Conversation:

“Current models assume carbon captured on land or in coastal waters will reliably make its way into long-term storage in the ocean. However, these models don’t replicate all Earth processes.”

“In reality, part of the engineered capture of carbon can be reversed as water moves through soils, rivers, estuaries and coastal environments. Dissolved elements can become trapped again in new minerals such as clays, reducing how much carbon ultimately remains stored over long timescales.”

     The researchers found, however, that there are carbon losses on the way to the sought-after long-term ocean storage, which can last for thousands of years.

‘However, different materials dissolve at different rates. Climate, rainfall, soil chemistry and biological activity also influence how quickly reactions occur. This means carbon removal can vary enormously between environments.”

“Earth systems also contain many opportunities for the flow of carbon to weaken before it ever reaches the open ocean.”

“As alkalinity moves through the environment, dissolved elements released during weathering can become trapped again in new minerals. These reactions can consume alkalinity and reduce the amount of carbon ultimately stored long term.”

     They also note that while carbon storage is enhanced where enhanced weathering takes place, natural carbon uptake downstream may be impeded, reversing some of the benefits.

“The challenge is whether Earth systems can keep the captured carbon stored or whether we are simply moving carbon across time and space instead of durably removing it from the atmosphere.”

Grid Utilization Rates Fall When Wind and Solar Rise: Build More, Use Less, Pay More is the Result


      Isaac Orr and Mitch Rolling in the Energy Bad Boys Substack refute the arguments made by Jigar Shah and others that it is only the lack of transmission that is impeding grid utilization rates, when that is only a part of the picture. Obviously, wind and solar resources are impeded by their intermittency, which is quite significant, as well as the limits on their capacity factors (solar up to about 24% and wind up to about 34%). For comparison, the avg. capacity factor for natural gas is in the high 50s percent, but would be much higher if those same resources were not used to back up renewables and then be taken offline when the renewables are available. Thus, it stands to reason that those natural limits on utilization virtually guarantee lower utilization rates for renewables, whether enough transmission is available or not.




     A couple of months ago I wrote about a study Jigar Shah was promoting, where computer simulations were showing that 300GW of existing transmission could be tapped since it was often not being used. I stated then that it would be great if that were true, but I was skeptical. They cite a similar study by Tyler Norris of Duke University that concluded that:

“…that nearly 100 GW of large new loads could be integrated with minimal impact if large electricity users temporarily reduce consumption during periods of grid stress by shifting workloads, utilizing on-site generation, or adjusting operations.”

     As the graph below shows, U.S. grid utilization has fallen steadily since it peaked in 1999 at 53.7% and fell to a record low of 39.4% in 2025.




     There is more proof in the graph below, which shows that since 1990, total installed capacity on the grid grew by 77%, but net generation only grew by 46%. However, it is mainly another way to show that grid utilization has dropped due to lower capacity factor generation growing on the grid.




     The graph below shows the relationship of price to grid utilization and installed capacity.




     Next, they go through the Net Zero America (NZA) study from Princeton University authored by Tyler Norris and Jesse Jenkins. They note that Jenkins was one of the biggest proponents of the Inflation Reduction Act (IRA). They note that the modeling in the study is highly dependent on using excess electricity to make green hydrogen.

“Importantly, the modeled NZA electricity generation growth figures are inflated by the model’s use of excess electricity to generate “green hydrogen.” This assumption then props up the fleet-wide utilization rates in the graphs below at around 30 percent, but it does so by assuming a massive increase in a technology that is collapsing around the globe.”

     The graph below shows how much each of the two scenarios: 1) E+ High Electrification and 2) E+RE+ (100 percent renewable) depends on green hydrogen production. The 100% renewable scenario is especially highly dependent on green hydrogen.




     The graph below models grid utilization rates under both scenarios from the study, compared to peak utilization and today's utilization rate. The E+ scenario would result in a 26% to 29% grid utilization rate depending on whether green hydrogen was made or not. The E+RE+ scenario would result in a 17% grid utilization rate with no green hydrogen and a 29% grid utilization rate with green hydrogen.




     Finally, they note that if there were no wind and solar on the grid over the years, the grid utilization rate would have remained high at 52%, which is just another way of saying wind and solar bring grid utilization rates down, which should be obvious to anyone who studies energy and electricity by now.





     They conclude:

“Overall grid utilization is falling in the United States because we added approximately 312,000 MW of wind and solar resources during a two-decade period when demand was essentially flat—which is also a great explanation on why prices have increased as much as they have.”

“Now that demand is surging again, the wind and solar advocates are using load factor as a red herring to hide the fact that they’ve spent billions of dollars increasing the size of the generation fleet, driving down overall utilization rates and increasing electricity prices as a result.”

Could Spare Chinese Refinery Capacity Be Used to Process More Crude into Oil Products for Export? RBN Energy Thinks It Is Plausible


     With Trump considering a diesel export ban, his advisors, including current DOE Secretary Chris Wright and his former first-term DOE chief Dan Brouliette, have argued against it. Wright said there will be some restrictions but not a ban on exports. Commentators have suggested that the effects of an export ban were uncertain and could actually lead to higher prices rather than the lower prices desired. With diesel selling for $6.53 per gallon, there is a clear need for lower prices. Those levels are not sustainable for farmers, truckers, and others who use diesel extensively. There are no real alternatives for them.

     Jason Lindquist and John Auers of RBN Energy asked whether spare Chinese refinery capacity could help world markets. They conclude that China could buy and refine more oil into products like diesel and export more for the global market. However, they note that China needs diesel too and conjecture that there are some Communist Party policies that may make it harder to refine and export more.

     The graph below shows that diesel and other oil products are not getting through the Strait of Hormuz. It has been a trickle, 100M Bbl /day at the trough in April to about 700 M Bbl/day now,  compared to 2025 when well over 3 MM Bbl/day were moving through the strait. That is about 15-22% of pre-war volumes.




     Persian Gulf refineries produce a lot of oil products, and several of those refineries have been bombed, dropping output by an estimated 2.5 MMb/d, two-thirds caused by refinery bombing. Less delivery of crude oil to refineries in Asia from the Middle East and Russia added to that, amounting to a 5.1 MMb/d cut in global refinery output. That means, even if they could send more, it won’t really happen until the refineries are back to partial and then full operation. Refineries have been bombed in Russia as well, which has taken more oil products off the global market. Thus, two wars, both conducted for protection against rogue militant states that do not accord with international laws and do not respect human rights at all (Russia and Iran). Russian refinery output has dropped dramatically to about 60% capacity utilization, the lowest in 20 years. Meanwhile, U.S. refineries are operating at over 95% average capacity utilization. We are also exporting refinery products as much as possible. They estimate that distillate exports averaged 1.56 MMb/d, 30% above the five-year average, in the past quarter. Thus, we can’t really refine or export any more than we are right now. But China can.

      They note that China has government controls on how much oil is refined and how much oil products are exported. They explain the details below:

“Crude-import quotas are one measure China uses to maintain market control. Independent “teapot” refiners generally need government authorization to import crude, allowing Beijing to influence both the volume of crude entering the country and which refiners can access it. State-owned companies such as Sinopec, PetroChina and CNOOC are subject to fewer of these constraints but remain closely aligned with broader government priorities, particularly energy security and domestic supply.”

“Refined product exports are another powerful tool. Beijing allocates export quotas for gasoline, diesel and jet fuel, effectively determining how much surplus production can be placed into international markets. When quotas are tight, refiners have less incentive to run at high rates because their ability to export excess product is constrained. Larger export allowances can have the opposite effect, allowing refiners to capture overseas margins and supporting higher utilization.”

     As the graph below explains, Chinese refiners dropped exports to about 400Mb/d due to the Strait of Hormuz disruption but are back up to normal at about 1 MM b/d since August. They note that China could double that export output to 2MM b/d, which would increase capacity utilization from the current 80% to about 85%.




     I had wondered when I saw the article headline whether Trump and Xi talked about this issue a couple of days ago when they met, and apparently the authors wondered as well. Trump asked Zelensky to stop bombing Russian refineries but I think he has a right to do whatever is necessary to thwart a brutal invading enemy.

“China’s refining sector won’t single-handedly solve the global refined-products squeeze, but it represents one of the few meaningful potential sources of additional supply available to the market in the short term. Beijing’s control over crude imports, refinery operations and, most importantly, export quotas gives it the ability to influence how much product reaches international buyers. With Middle Eastern and Russian supply still constrained and U.S. refiners running near full tilt, even a modest increase in Chinese exports could take some pressure off global balances. The question is not whether China has the barrels, but whether Beijing decides it wants to supply them to meet global market needs. With President Trump scheduled for a state meeting with Chinese President Xi Jinping on Thursday in Washington, the topic certainly could come up. While refined product exports are unlikely to be a headline Trump-Xi negotiating item, they could be part of a broader discussion about global fuel availability and energy-market stabilization, topics of mutual interest to the U.S. and China.”

Power Conversion Systems Aid Electrification, Digital Optimization, and Manage Energy Storage Applications


     According to an AI overview from Microsoft Copilot:

“Power Conversion Systems (PCS) are critical technologies that convert and regulate electrical energy between AC and DC forms, enabling efficient energy storage, grid integration, and renewable energy management.”

     The summary from Microsoft Copilot is given below:






     Power conversion systems are essential for EVs, solar power, wind power, and grid battery storage. Solarbridge notes that trends are moving from centralized power to decentralized power, and PCSs are a key to that change. They note:

“At its core, a Power Conversion System (PCS) is an advanced electrical device that converts electric power from one form to another to make it usable for a specific application.”

     They point out that a PCS is not merely an inverter that changes DC to AC. It manages bidirectional flow, which is required for batteries to be tapped for power when needed for grids or applications. It is the hardware that enables batteries to charge when power prices are low and discharge when they are high. A PCS also keeps voltage, frequency, and power quality stable when battery charge and discharge occur. Below, they describe the three functions of a PCS: 1) rectification (converting AC to DC), 2) inversion (converting DC to AC), and 3) power quality regulation by adjusting voltage and frequency. The last function, regulating power quality, is also known as grid-forming or grid-following. It happens in milliseconds via software-controlled switching.




     The benefits of PCSs include enabling energy arbitrage where power can be bought low and sold high for net cost savings. Grids can do this, but so too can commercial and residential customers. A PCS can provide resilience during a power outage by disconnecting from the grid, or islanding, and running needed devices with the battery system and/or solar generation system, essentially becoming a microgrid. Businesses use these setups to avoid losses during outages.

     They note that PCSs are modular and for businesses are often begun at 100kW size. Solarbridge sells PCS modules, hybrid inverters, and integrated all-in-one PCS/BESS energy storage solutions, all made in the USA. They note that there are many cheap imported PCS systems that are inadequate or mismatched to U.S. power needs. They lack support and may not meet grid codes.

     PCSs are expected to last 15-20 years. They note that they can work with most available battery chemistries. In most cases, a PCS replaces the need for a separate inverter. Earlier this month, I posted about a two-year study commencing to test different grid-forming inverter models and their ability to help stabilize the grid and reduce the need to use spinning inertia for grid balancing. Grid-forming inverters work by a different mechanism than the spinning inertia of turbines and motors.   

     Company Vicor Power makes power modules for EVs, and its modular approach allows for the same power architecture to be deployed across vehicle platforms. They design for range boost when needed, and their modules can be used to optimize power, weight, and package space. Their modules are isolated and bidirectional.







     Danfoss is another company that builds and sells PCSs, among many other power products. They offer “an extensive range of power converters and variable frequency drives for use in power systems for a wide range of applications across all industries.”
