Houston energy technology company SLB announced a contract award by Petrobras to its OneSubsea joint venture for two subsea raw seawater injection systems to increase recovery from the prolific Búzios field in offshore Brazil.

The subsea RWI systems will work to increase the production of floating production storage and offloading (Petrobras FPSO) vessels that are currently bottlenecked in their water injection capacities.The RWI systems, once operational, can reduce greenhouse gas emissions per barrel of oil.

“As deepwater basins mature, we see more and more secondary recovery opportunities emerging,” Mads Hjelmeland, CEO of SLB OneSubsea, says in a news release. “Subsea raw seawater injection is a well-proven application with a strong business case that we think should become mainstream. By placing the system directly on the seabed, we free up space and reduce fuel needs for the FPSOs as well as lessen the power needs for the injection systems. It’s a win-win for Petrobras, and one that we are very excited about.”

SLB OneSubsea works to “optimize oil and gas production, decarbonize subsea operations, and unlock the large potential of subsea solutions to accelerate the energy transition,” per to the company.

SLB OneSubsea is contracted to provide two complete subsea RWI systems to support Petrobras’ FPSOs P-74 and P-75. They will consist of a subsea seawater injection pump, umbilical system and topside variable speed drive. In addition,the team will also provide technical support using AI-enabled Subsea Live services, which includes condition monitoring and access to domain experts.

“This contract will consolidate our solid local content presence in the country, contributed by the largest manufacturing plants and state-of-the-art subsea service facilities in Brazil,” Hjelmeland continues.

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.

Annual offshore conference in Houston names honorees for leadership, sustainable efforts

otc 2024

The 2024 Offshore Technology Conference has revealed the three Distinguished Achievement Award recipients that will be recognized at the conference next month.

OTC, a conference that has served the offshore energy community for over 50 years, will bring 276,000 square feet of exhibit space to NRG Park and welcome over 31,000 attendees for more than 350 sessions. The awards reception will kick off the week on May 5.

One of the awards recipients named is Kerry J. Campbell, who will accept the OTC Distinguished Achievement Award for Individuals. Campbell was selected based on his "work in developing modern deepwater site characterization practice and for teaching and mentoring generations of site characterization professionals," reads the news release.

He's previously co-chaired sessions at OTC and served on a subcommittee for the organization, in addition to co-writing seventeen OTC papers. He retired from Fugro in 2020 after helping integrate 3D marine seismic data for engineering applications.

Petrobras will accept the OTC Distinguished Achievement Award for Companies, Organizations, and Institutions at the May banquet. The company was selected "for the deployment of a wide set of new technologies for the successful revitalization of the Marlim Field and the entire deepwater Campos Basin, unlocking new paths for mature deepwater asset redevelopment, with significant reduction in greenhouse gas emissions," per the release.

For about 50 years, the Campos Basin has been subjected to exploration and is known for various shallow water discoveries. In 1992, Petrobras was recognized for its deepwater development in Marlim, and over 30 years later, the company will be praised for its work redeveloping mature fields and the pioneering subsea, drilling, reservoir and decommissioning technologies.

The third and final award recipient is EnerGeo Alliance, which will receive the OTC Special Citation award for promoting efficiency and environmental sustainability within offshore seismic data collection.

"For more than 50 years, EnerGeo Alliance has been a stalwart in the quest for accessible, affordable energy around the globe, while also being a standard-bearer for safety and the environment," reads the release. "EneGeo Alliance has set the standard in the energy geoscience industry by establishing best practices and recommended guidance in key energy areas, including its Environmental Impact Assessment Handbook and Greenhouse Gas Emissions Guidance, for its members."

Engineering tech co. expands collaboration with Houston robotics startup in $2.1M contract extension

underwater moves

A major customer of Webster-based Nauticus Robotics, a maker of autonomous oceangoing robots, has bulked up its current contract.

Reston, Virginia-based Leidos has tacked on a $2.1 million extension to its existing contract with Nauticus. That brings Leidos’ total financial commitment from $14.5 million to $16.6 million.

In partnership with Leidos, Nauticus is developing next-generation underwater drones for business and military customers. These unmanned underwater vehicles are being designed to carry out tasks that are dangerous or impossible for human divers to do, such as mapping the ocean floor, studying sea creatures, and monitoring water pollution.

“This very important work combines great attributes from each company to deploy a truly novel subsea capability,” says Nicolaus Radford, founder and CEO of Nauticus.

Based on Nauticus’ Aquanaut product, these robots will feature the company’s toolKITT software, which supplies artificial intelligence capabilities to undersea vehicles.

“This work is the centerpiece of Nauticus’ excellent collaboration with Leidos,” says Radford, “and I look forward to continuing our mutual progress of advancing the state of the art in undersea vehicles.”

Founded in 2014 as Houston Mechatronics, Nauticus adopted its current branding in 2021. Last year, Nauticus became a publicly traded company through a merger with a “blank check” company called CleanTech Acquisition Corp.

During the first six months of 2023, Nauticus generated revenue of nearly $4 million, down from a little over $5.2 million in the same period last year. Its operating loss for the first half of 2023 was almost $12.7 million, up from slightly more than $5.2 million during the same time in 2022.

Nauticus attributes some of the revenue drop to delays in authorization of contracts with government agencies.

The company recently lined up a $15 million debt facility to bolster its operations.

“I’ve never been more optimistic about the future of Nauticus. We employ some of the best minds in the industry, and we are positioned with the right product at the right time to disrupt a $30 billion market,” Radford said earlier this month. “Demand from potential customers is high, but constructing our fleet is capital-intensive.”

More good news for Nauticus: It recently signed contracts with energy giants Shell and Petrobras. Financial terms weren’t disclosed.

The Shell contract involves a project in the Gulf of Mexico’s Princess oil and gas field that Nauticus says could lead to millions of dollars in additional contracts over the next few years. Shell operates the offshore field, which is around 40 miles southeast of New Orleans, and owns a nearly 50 percent stake in it.

Co-owners of the Princess project are Houston-based ConocoPhillips, Spring-based ExxonMobil, and London-based BP, whose North American headquarters is in Houston. In July, the Reuters news service reported that ConocoPhillips was eyeing a sale of its stake in the Princess field.

Under the contract with Petrobras, whose U.S. arm is based in Houston, Nauticus will dispatch its Aquanaut robot to support the Brazilian energy company’s offshore activities in South America. Nauticus says this deal “opens up a potential market opportunity” in Brazil exceeding $100 million a year.

Houston robotics company secures deal with Brazilian energy giant

sea change

Houston-based Nauticus Robotics, a developer of autonomous ocean robots, has landed a deal to supply its equipment to one of the world’s largest energy companies — a deal that eventually could blossom into $100 million worth of contracts.

Under the deal, Nauticus will dispatch its Aquanaut autonomous subsea robot to support offshore oil exploration activities carried out by Brazil’s Petrobras. Specifically, Aquanaut — propelled by artificial intelligence-enabled software — will supervise infield inspection services over a two-month span.

The deal with Brazil’s Petrobras represents Nauticus’ entry into the South American market and puts Nauticus in a position to score several Petrobras contracts that could collectively be valued at $100 million. Both companies are publicly traded.

Nicolaus Radford, founder and CEO of Nauticus, says Brazil offers a significant market opportunity for his company, as South America’s largest nation boasts one of the world’s most active offshore energy basins.

“A contract with [a] worldwide leading operator for Nauticus speaks to the state-of-the-art technologies of our autonomous robots as we further penetrate the global markets,” Radford says in a news release.

Petrobras is one of the world’s biggest offshore operators, managing 57 platforms, operating 10,000 miles of oil and gas pipelines, and producing the equivalent of 2.6 million barrels of oil per day. The company generated $124.47 billion in revenue last year.

Founded in 2014, Nauticus posted revenue of $11.4 million in 2022. The company went public last year through a $560 million merger with a special purpose acquisition company (SPAC). Nauticus recently opened a new office in The Ion, in addition to their Webster office.

“I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow,” Radford told InnovationMap in May. “We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.”

Houston cleantech startup secures $134M to develop ‘superhot’ geothermal plant

deep round

Houston-based Quaise Energy, a producer of utility-scale geothermal power, raised $134 million in a Series B round to advance its “superhot” geothermal power plant.

Climate-focused San Francisco-based investment firm Prelude Ventures led the round, with participation from JERA Co., Japan’s largest power generation company, and Idemitsu Kosan, one of Japan’s largest energy companies. Nearly all existing investors, including cleantech-focused investment firm Safar Partners, participated in the round.

“We have backed Quaise since the beginning because we believed accessing superhot rock would unlock geothermal energy at a scale the world has never seen,” Mark Cupta, managing director at Prelude Ventures, said in a press release.

The startup expects more equity and debt deals to close “imminently.” Quaise has raised $230 million since its founding in 2018.

Quaise says some of the fresh funding will go toward building the world’s first commercial-scale “superhot” geothermal power plant —Project Obsidian in central Oregon. In addition, Quaise is earmarking money for continued development and commercialization of its millimeter-wave drilling system toward depths exceeding 5 kilometers (about 16,400 feet).

Quaise uses a millimeter-wave drilling system developed at the Massachusetts Institute of Technology to remove rock at depths and temperatures that aren’t economically feasible with conventional drilling. With this technology, Quaise can reach rock at temperatures of around 570 degrees to 930 degrees in most places worldwide, enabling construction of geothermal systems that rival fossil fuels and nuclear energy in power density and that rival renewables in cost.

“Our ambition is to power civilization with Earth's most compelling energy source. This round takes us from field-proven technology to first commercial revenues,” Carlos Araque, co-founder, president and CEO of Quaise, added in the release.

Quaise has demonstrated the capability of its millimeter-wave drilling system at its Central Texas test site, drilling more than about 330 feet through granite in 2025—the first time the technology penetrated basement rock at full scale in the field. The company is approaching a depth of about 3,300 feet at the same site.

Construction of Project Obsidian is underway at Oregon’s Deschutes National Forest. The project, which has the potential to generate gigawatt-scale power, is slated to deliver electricity to the Pacific Northwest grid by 2030.

Shell expands lower-carbon energy solutions while cutting emissions

The View from HETI

Shell’s approach to sustainable development reflects an integrated value chain perspective—reducing emissions from oil and gas production, transforming downstream businesses to offer more low-carbon solutions, and building new energy businesses at scale. The company’s 31% reduction in Scope 1 and 2 operational emissions since 2016 demonstrates that this integrated strategy delivers results.

Three Strategic Priorities Drive Progress

Leading Integrated Gas: Shell is growing its world-leading LNG business with lower carbon intensity, meeting rising demand for natural gas as a transition fuel and foundation for renewable energy integration.

Advantaged Upstream: The company is cutting emissions from oil and gas production while keeping output stable, proving that operational excellence can reduce environmental impact without sacrificing energy security.

Differentiated Downstream, Renewables, and Energy Solutions: Shell is transforming its businesses to offer more low-carbon solutions while reducing sales of traditional oil products, positioning the company for the evolving energy market.

Shell’s emissions reductions are happening across global operations:

  • United States: Significant emissions cuts from production assets through operational efficiency and technology deployment
  • Malaysia & Philippines: Emissions reduction programs at offshore operations demonstrating that low-carbon production works in diverse environments
  • Norway: Continued emissions intensity improvements from mature assets, showing that even older fields can decarbonize

Whale Partnership Demonstrates Innovation

Shell’s recent partnership with Chevron at the Whale deepwater asset showcases what’s possible with next-generation project design. By integrating emissions reduction strategies from the start, the partnership has lowered the greenhouse gas intensity approximately 30% over the project lifecycle relative to similar deepwater oil and gas production assets.

Shell’s strategy to deliver more value with less emissions includes climate change transition plans, mitigation actions and decarbonization levers supported by a suite of processes and greenhouse gas emission reduction targets such as:

2025 Results:

  • Eliminated routine flaring from upstream operations
  • Maintained methane emissions intensity below 0.2%

By 2030:

  • Halve Scope 1 and 2 emissions under operational control (vs. 2016)
  • Achieve near-zero methane emissions
  • Reduce Scope 3 net carbon intensity (NCI) by 15-20% (vs. 2016)
  • Cut customer emissions from oil products by 15-20% (vs. 2021)

By 2050:

  • Achieve net zero emissions across Scopes 1, 2, and 3

Across all strategic initiatives, Shell prioritizes trading and optimization capabilities that maximize value while minimizing emissions. This commercial approach ensures that the company’s energy transition strategy creates long-term shareholder value while advancing climate goals.

Shell is building an integrated energy business for the low-carbon future by delivering the energy products customers need today while investing in the solutions they’ll need tomorrow.

As a steering-level member of HETI, Shell exemplifies the leadership and commitment required to transform Houston’s energy sector while maintaining global energy security.

UH report projects $1T in new midstream infrastructure needed to power AI era

midstream report

A new study from the University of Houston estimates that the U.S. will need more than $1 trillion in new midstream energy infrastructure investment by 2052 to meet the rising energy demands from data centers in the age of artificial intelligence.

According to the report, this would average $40 billion to $48 billion per year across investments in natural gas, oil, natural gas liquids, hydrogen and CO2 infrastructure.

UH, in collaboration with the INGAA Foundation and Wood and ESMIA Consultants, released the 2025 North American Midstream Infrastructure Report, which details the needs, pipelines and associated infrastructure necessary to meet global market needs and increased energy demands. UH led the consortium that conducted the analysis. Paul Doucette, hydrogen program officer at UH, served as the principal investigator of the report.

According to the U.S. Department of Energy, data center energy consumption could reach 800 terawatt-hours annually by 2050, a roughly 167 percent increase from 300 terawatt-hours in 2025. Meanwhile, electricity generation from all energy sources is projected to reach 5,858 terawatt-hours in 2052, a 27 percent increase over current levels.

The report proposes two routes to meeting this level of demand.

The first scenario is a reference case based on current federal, state and provincial policies as of April 1, 2025. The second option presents a low-carbon scenario. The report concludes that natural gas would need to remain a “foundational component of the region’s energy system” in both scenarios.

“Meeting energy demand is a critical challenge right now, and this report quantifies the necessary midstream infrastructure and corresponding development dollars needed to meet that demand,” Hebe Shaw, executive director of the INGAA Foundation, said in a news release. “Meeting the energy needs of North America will require sustained investment and development, which must begin now to ensure a safe, reliable and affordable energy system.”

The report also identified several key midstream infrastructure requirements, including:

  • 103,000 miles of new natural gas gathering pipelines
  • 37,000 miles of additional natural gas transmission pipelines, which includes approximately 33,800 miles in the United States
  • 24 million jobs over 25 years

The report adds that hydrogen, carbon capture, utilization, and storage (CCUS), and other decarbonization strategies can help meet infrastructure needs.

UH released a condensed version of the report here.
