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.

offshore optimization

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.”

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
