Slovakian geothermal drilling technology company GA Drilling, whose U.S. headquarters is in Houston, has teamed up with Brazilian energy giant Petrobras to reduce well construction costs and well-drilling risks.

Under the new partnership, GA Drilling will work with Petrobras’ R&D center to roll out an autonomous drilling system that enables drilling at offshore wells from a light vessel instead of a costlier semi-submarine or drill ship.

“Taken together, the benefits of our drilling technologies equal better efficiency, leading to lower costs, [a] smaller operational footprint, and ultimately lower risk overall,” Igor Kočiš, co-founder and CEO of GA Drilling, says in a news release.

GA Drilling says its drilling system improves drilling efficiency and enables replacement of conventional drill pipes with lower-risk tubes. Features of the system include drilling automation and control systems, and real-time communications.

In April 2024, GA Drilling announced it had closed on $15 million in funding. Investors included Houston-based oil and gas drilling contractor Nabors Industries, the newly established Underground Ventures geothermal investment fund, and Slovakian venture capital firm Neulogy Ventures.

A year earlier, GA Drilling conducted the first public demonstration of its Anchorbit drilling tool at a Houston test well owned by Nabors. The tool is designed to simplify and improve drilling into high-temperature hard rock formations.

Why Nabors wants to be an early leader within the energy transition

Q&A

With over 70 years of experience, Nabors Industries has established itself as one of the largest land contract drilling companies in the world, as well as a provider of offshore platform rigs in the United States and international markets. But how is the company thinking of its next decades amid the energy transition?

Considering the role Nabors is playing in the future of energy is Houston-based Guillermo Sierra's job as vice president of energy transition. In a Q&A with EnergyCapital, he explains how the company envisions its future as an energy leader and what all that entails, including sourcing new technologies — sometimes from promising startups like Sage Geosystems.

EnergyCapital: Tell me about Nabors' commitment to the energy transition. What are your responsibilities leading this initiative?

Guillermo Sierra: Understanding that no single source today consistently delivers affordable, reliable and responsible energy, Nabors sees its future innovating solutions for hydrocarbons and clean energy while removing the tradeoffs between them. “Energy Without Compromise” is the vision guiding these efforts. Ultimately, we view three critical paths for the industry and ourselves to realize this:

Embrace energy innovation over energy exclusion. Too often the energy transition conversation is about excluding particular sources when we should be focused on solving challenges or overcoming limitations with technology. Oil and gas provide affordable and reliable energy but we must address emissions. Renewables are a greener solution but powering society, heavy industries, and hard-to-abate sectors requires sources that are clean, scalable, and baseload-seeking. For our part, we are lowering the carbon intensity of oil and gas operations with AI-based engine management software, fuel enhancers, highline power solutions, energy storage and forthcoming hydrogen injection systems while also investing in geothermal, concentrated solar power, alternative energy storage, emissions monitoring, hydrogen, and advanced materials, to make renewables a viable solution to decarbonize the industrial and energy industries.
Capitalize on strengths and adjacencies. Companies should seek opportunities to apply skillsets and competencies to advance other industries in the pursuit of a sustainable future. It is easy to see how our drilling expertise is valuable to the geothermal industry. Those companies need to drill wells and use technology that’s been developed by the oil and gas industry for decades to produce heat instead of hydrocarbons. Beyond the drill bit though, companies in the broader clean energy community see tremendous strategic value in partnering with Nabors. Our robotics, remote operations, software, automation, AI, manufacturing and engineering capabilities, global customer base of some of the world’s largest companies, worldwide vendor relationships and supply chain can be used to help startups grow and scale much more quickly.
Collaborate to accelerate progress. The proverb is if you want to go fast, go alone. If you want to go deep or go far, go together. Working together and leveraging collective strengths will help us solve some of the most meaningful challenges. There’s room for us all and we need to work together to achieve emissions goals.

EC: When considering a clean tech company, what are the top qualities driving your investment decisions? How did Sage Geosystems fit what you were looking for?

GS: Traditionally, renewables have stumbled some in the power business because they are intermittent and therefore not dispatchable or reliable baseload. There are also safety, supply chain, and environmental challenges to overcome with lithium-ion batteries and the lack of circularity of panels, blades, and other equipment. Additionally, to decarbonize industrial processes, you need clean and efficient sources of heat – which have largely been nonexistent. And the broader industrials complex needs green fuels, hydrogen and sustainable aviation fuel to eliminate their carbon footprint.

Therefore we believe the world needs clean, renewable, scalable, and baseload/dispatchable generation, and alternatives to today’s chemical-based energy storage. When we evaluate our investments, this is what we’re ultimately seeking.

Sage checks every one of these boxes. The company envisions producing renewable baseload power from geothermal and has novel solutions to energy storage. And unlike many geothermal companies, their approach is deployable today with off the shelf technologies.

EC: What role do you see enhanced geothermal playing in the energy transition?

GS: In my opinion, geothermal has been the gaping hole so to speak in net zero plans from companies and governments. Less than 1 percent of the earth is cooler than 1,000 degrees Celsius. Heat gradients needed are miles away while the sun is 93 million miles away. The oil and gas industry has spent decades perfecting how we drill safely and efficiently. We have near limitless energy beneath our feet and have the tools to tap it. Now we need the focus and capital of the broader energy complex.

EC: How big are your long-term aspirations for Nabors in regards to the energy transition?

GS: I believe the energy transition will represent one of the biggest reallocations of capital in human history. By some estimates, some $300 trillion is expected to spent. We want to be a leader. We want in early. We believe we have the skills, competencies, workforce, relationships, and scale to make a meaningful impact and we are taking action.

Houston-based geothermal energy startup releases promising results of Texas pilot

hot off the press

As it seeks an additional $30 million in series A funding, Houston startup Sage Geosystems has released promising results from a test of its technology for underground storage of geothermal energy.

Sage says the pilot project, conducted at a Shell-drilled oil well in the Rio Grande Valley’s Starr County, showed the company’s long-term energy storage can compete on a cost basis with lithium-ion battery storage, hydropower storage, and natural gas-powered peaker plants. Peaker plants supply power during periods of peak energy demand.

Furthermore, Sage’s geothermal technology will provide more power capacity at half the cost of other advanced geothermal systems, the company says.

Sage’s storage system retrofits oil and gas wells with the company’s geothermal technology. But the company says its technology “can be deployed virtually anywhere.”

The system relies on mechanical storage instead of battery storage. In mechanical storage, heat, water, or air works in tandem with compressors, turbines, and other machinery. By contrast, battery storage depends on chemistry to get the job done.

“We have cracked the code to provide the perfect complement to renewable energy. … The opportunities for our energy storage to provide power are significant — from remote mining operations to data centers to solving energy poverty in remote locations,” former Shell executive Cindy Taff, CEO of Sage, says in a September 12 news release.

Sage says its storage capacity can be connected to existing power grids, or it can develop microgrids that harness stored energy.

An August 2023 article in The New York Times explained that Sage “is pursuing fracked wells that act as batteries. When there’s surplus electricity on the grid, water gets pumped into the well. In times of need, pressure and heat in the fractures pushes water back up, delivering energy.”

The pilot project, a joint venture between Sage and the Bureau of Economic Ecology at the University of Texas at Austin, was performed as part of a feasibility study financed by the Air Force. Now that the test results are in, Sage plans to build a prototype geothermal project at the Air Force’s Ellington Field Joint Reserve Base in Houston.

Sage says another feasibility study is underway in the Middle East in partnership with an unnamed oil and gas company.

Founded in 2020, Sage plans to raise another $30 million to accompany its previous series A funding.

The Virya climate fund and Houston-based drilling contractor Nabors Industries helped finance the pilot project in Starr County.

Last year, Sage announced it received an undisclosed amount of equity from Houston-based Ignis H2 Energy, a geothermal exploration and development company, and Dutch energy company Geolog International. Also last year, Sage said Nabors and Virya had teamed up for a $12 million investment in the startup.

Drilling executive calls for a new course of action to achieve success

EMPOWERING TRANSITION

Gone are the days of people, process, and technology. Welcome to purpose, partnering, and governance.

In the early morning hours of the third day of OTC2023, Subodh Saxena, senior vice president at Nabors Industries, succinctly summarized both the challenges and opportunities faced by an industry in the middle of an identity crisis.

The upstream energy industry focused the better part of the last two decades on physical safety, division and clarity of responsibilities, and technology adoption and adaptation. Rightfully so, given the Macondo incident of 2010, the Enron collapse in 2002, and the general wildfire growth of technology in the workplace over the same time frame.

But as leadership that came of age during these tragedies takes the reigns, a new set of challenges arises. Consistent lack of positive financial returns, a shrinking talent pool, and of course, the climate crisis, combine to form the perfect storm for an industry just trying to manage the rising and falling tides of unstable commodity pricing.

To avoid completely capsizing during this squall in which the industry finds itself, Saxena describes three opportunities for improvement.

Attracting new talent by creating psychological safety in our workplaces and improving the perception of technology adaptation in the industry

Embracing a collaborative approach to building new solutions to limit the amount of siloed rework that currently stymies rapid advancement

Improved financial discipline with greater honesty about ROI for the entire supply chain

“We have a mindset in the industry, that we have to build everything ourselves," Saxena laments. "We have to learn to partner because [if] every company invests in new technology to create transition, whether that's hydrogen or any other source of green energy, that return on invested capital is going to become negative. We need to learn to collaborate to ensure that we are all going to be successful.”

The requests made by Saxena represent a growing movement within the incumbent industry to think not of the energy transition as a shift from one energy source to another but as a transition in mindset. Collaboration is the name of the game now, as are mindfulness, responsibility, and above all else, sustainability.

Revisiting purpose, partnering, and governance to identify room for improvement will ultimately determine whether organizations will sink or sail.

Houston companies win big at Elon Musk-backed carbon removal competition

xprize winners

Houston-based Mati Carbon has won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

Mati was selected in 2024 as one of 20 global finalists. The company removes carbon through its Enhanced Rock Weathering (ERW) program that works with agricultural farms in Africa and India.

The 3-year-old startup accelerates the natural process of rock weathering (ERW) by applying pulverized basalt to croplands of partnered smallholder farmers, free of charge. Mati says the farmers it partners with are some of the most vulnerable to the impacts of climate change.

“Winning this XPRIZE competition is an incredible honor and a definitive validation of our research and development, and building out the infrastructure needed to impact millions of farmers while delivering verifiable carbon dioxide removal at a gigaton scale,” Mati Carbon Founder and CEO Shantanu Agarwal, said in a news release. “I couldn’t be prouder, not just of the Mati team, but of our collaborators, research partners and the thousands of smallholder farmers who let us be part of their lives. This XPRIZE recognition will allow us to collaborate with local partners to accelerate the use of enhanced rock weathering across the Global South.”

Mati reports that it plans to use the award to “scale its efforts working with smallholder farmers worldwide.” Apart from the XPRIZE funding, Mati plans to grow its model through the sale of CDR credits. According to the company, it counts Shopify, Stripe, and H&M among its early carbon credit buyers.

“Mati Carbon’s deployments bolster farmers’ livelihoods through improved soil health, reduced agricultural inputs, and increased income at zero cost to them. Mati Carbon’s team has developed a scientifically rigorous approach to monitoring and verification, and excelled across each of XPRIZE’s prize evaluation criteria – operational, sustainability, and cost metrics – giving the XPRIZE judges the highest confidence in Mati Carbon’s solution’s long-term scalability,” the XPRIZE judges wrote.

Houston-based Vaulted Deep took home the second-runner-up prize in the competition and $8 million for its organic waste storage process. The company provides permanent carbon storage by injecting nonhazardous organic waste deep underground. It spun off with $8 million in seed funding from Advantek Waste Management Services in 2023.

"Our approach is grounded in geomechanical injection techniques that have been safely deployed globally for decades by our team and predecessors," Omar Abou-Sayed, co-founder and executive chairman of Vaulted, said in a separate release. "XPRIZE recognized that this is a proven approach—already in use, delivering impact, and built on the kind of reliability the industry needs to scale responsibly."

Launched in 2021, the four-year XPRIZE Carbon Removal competition challenged global innovators to deploy scalable solutions for removing carbon dioxide from the atmosphere and oceans. More than 1,300 teams from 88 countries competed. XPRIZE finalists were required to remove at least 1,000 tonnes of CO2 over a one-year demonstration period.

French company NetZero took home the first-runner-up prize of $15 million, and London-based UNDO came in as third-runner-up with a $5 million prize.

Since the announcement of the XPRIZE Carbon Removal competition, the Musk-led Department of Government Efficiency has cut climate funding for agencies, projects and research. While the Musk Foundation sponsored the XPRIZE event, it is not affiliated with the California-based organization, according to the Associated Press.
