Two lawyers have joined Winston & Strawn's energy practice in Houston.

Kevin Brophy and Ming Lei were named as partners and members of the firm's transactions department.

“Kevin and Ming’s extensive experience executing all manner of sophisticated transactions for energy and infrastructure clients combined with their strong networks in the energy sector enhance Winston’s position in Texas as one of the strongest firms for handling these transactions,” Mike Blankenship, Houston office managing partner, says in a news release. “Their complementary skills will help expand our work with private equity firms and other companies operating in the energy sector.”

Brophy's focus includes upstream and midstream sectors, and Lei advises clients on energy transition, as well as oil and gas exploration, storage, refinery, and more. Both have expertise in mergers and acquisitions, joint ventures, asset acquisitions and dispositions, and more.

Houston law firm expands energy practice to Paris

bon voyage

It's not just United States athletes descending upon France this summer. A Houston-based law firm has announced the expansion of its energy team into the region.

Bracewell LLP has opened an office in Paris La Défense and named 11 energy and infrastructure lawyers from Norton Rose Fulbright to the new location, which will be focused on project development, M&A, and finance transactions in the energy and infrastructure sectors. The team will have an emphasis on renewable and conventional power, energy transition, oil and gas, and infrastructure in France — as well as Europe, the Middle East, and Africa, per a news release from the firm.

“We are thrilled to welcome our new colleagues to the firm and to open an office in Paris,” Bracewell Managing Partner Gregory M. Bopp says in the release. “The addition of this energy and infrastructure team, one of the largest and most highly regarded in Paris, builds on the strengths of our preeminent global energy platform and broadens our capabilities in France, Africa, and the broader EMEA region.”

Anne Lapierre, Arnaud Bélisaire and Simon Cudennec joined Bracewell as partners in Paris. Eight associates and counsel complete the team: Véronique Bruel, Marie Zelazko, Adnen Ben Naser, Sandra Hahn Duraffourg, Pierrick Ferrero, Diane Dusserre, Noémie Portut-Castel, and Carl Kalaani.

“The French team is a pure energy and infrastructure team, which mirrors who we are and what has been successful in London,” Jason Fox, managing partner of Bracewell’s London office, says in the release. “Where the London office has a strong focus on the oil and gas sector, the French team is more focused on renewables. That, combined with the addition of French law and OHADA capabilities, complements our platform and strengthens our renewables offering, notably in Francophone Africa.”

Lapierre previously served as head of Norton Rose Fulbright’s global energy practice, and Bélisaire co-led that firm's energy practice in Paris. Cudennec, also from Norton Rose Fulbright, specializes in projects within the energy, infrastructure and natural resources sectors in France and French-speaking Africa.

“Bracewell’s focus on sector excellence has made it one of the leading energy law firms in the world,” adds Lapierre. “Arnaud, Simon and I are thrilled to join an outstanding and dedicated global team that has broad capabilities and a sterling reputation across the entire energy spectrum.”

Houston battery recycling company secures $32M in financing

fresh funding

Houston-based Ace Green Recycling has raised $32 million in private investment in public equity (PIPE) financing to support its future plans for growth.

The battery recycling technology company secured the financing with Athena Technology Acquisition Corp. II, a publicly traded special purpose acquisition company that Ace previously announced it plans to merge with. Once the merger is completed, Ace will become a publicly traded company on the Nasdaq Stock Exchange under the ticker symbol "AGXI."

Ace says the financing will be used to complete the merger and scale the company.

“This investment accelerates our mission to redefine battery recycling at a global scale,” Ace CEO Nischay Chadha said in a news release. “At Ace, we are deploying Greenlead® and LithiumFirst™ as a new standard–fully electrified, Scope 1 emissions-free solutions designed to replace legacy processes and unlock a cleaner supply chain for critical materials. We believe that the future of electrification depends on how efficiently and sustainably we recover these resources, and this milestone brings us meaningfully closer to that future.”

Ace says the funding will also be primarily used to fund capital expenditures related to the development of its planned flagship recycling facility, located outside of Beaumont, Texas. According to a February investor presentation, the facility is expected to launch in 2027. It will recycle lead-acid and lithium-ion batteries.

Ace agreed to a 15-year battery material supply agreement with Miami-based OM Commodities last year, in which OM Commodities would supply Ace with at least 30,000 metric tons of lead scrap to be recycled annually. Switzerland-based Glencore plc agreed to a 15-year offtake agreement to purchase up to 100 percent of ACE’s products from four of its planned lead-acid and lithium-ion battery recycling parks back in 2022.

Ace also reported that the funding will be put toward "supporting the expansion of operations and to fund the purchase of other companies," in the release.

Houston AI startup rolls out platform to reshape oil and gas workflows

AI for energy

Houston-based Collide is looking to solve AI issues in the energy industry from within.

Co-founded by former oil roughneck Collin McLelland, the company has developed AI software for operators and field teams, shaped by firsthand oilfield experience. Its AI-native platform “retrieves and synthesizes data from authoritative sources to deliver accurate, cited, and energy-focused insights to oil and gas professionals,” according to the company.

“Oil and gas has a graveyard full of technology that was technically impressive and operationally useless,” McLelland tells Energy Capital. “The reason is almost always the same: the people who built it didn't understand what they were actually solving for. When you're an outsider, you see workflows and try to automate them. When you're an insider, you understand why those workflows exist—the regulatory constraints, the physical realities, the liability concerns, the trust dynamics between operators and service companies.”

Collide’s large language model, known as RIGGS, performed well in recent benchmarking results when taking a standardized petroleum engineering (SPE) exam, the company reports. The exam assesses understanding from conceptual terminology to complex mathematical problem-solving.

According to Collide, RIGGS achieved a score of 67.5 percent on a 40-question subset of the SPE petroleum engineering exam, outperforming other large language models like Grok 4 (62.5 percent), Claude Sonnet 4.5 (52.5 percent) and GPT 5.1 (4 percent).

RIGGS completed the test in 15 minutes, while Grok took two hours. Collide hopes over the next few months, RIGGS will receive a score between 75 percent to 80 percent accuracy.

The software could potentially help oil and gas companies produce accurate outputs and automate trivial workflows, which can open up valuable time for engineers and teams to work on other pressing matters, according to McLelland.

“Collide exists because we sat in those seats — we were the engineers, the operators, the field guys,” he says. ”RIGGS scoring higher on the PE exam versus the frontier labs isn't a party trick. It's evidence that the model understands petroleum engineering the way a petroleum engineer does, because it was built by people who do.”

RIGGS was trained on Collide’s Spindletop hardware and is supported by a vast library of information, as well as a reasoning engine and validation layer that uses logic to solve problems.

“Longer term, we see RIGGS as the intelligence layer that sits underneath every operator's workflow — not a chatbot you open in a browser, but something embedded in the tools engineers already use,” McLelland says. “The goal is to give every engineer the knowledge and pattern recognition of a 30-year veteran, on demand."

According to McLelland, Collide is already building toward reservoir analysis and production optimization, automated regulatory compliance (Railroad Commission filings, W-10s, G-10s), workover report generation, and engineering decision support in the field for near-term use cases. In March, Collide and Texas-based oil and gas operator Winn Resources announced a collaboration to automate the time-intensive process of filing monthly W-10 and G-10 forms with the Texas Railroad Commission, completing what’s normally a multi-hour task in under 30 minutes. Collide reports that Winn’s infrastructure now automates regulatory filings and provides real-time visibility into data gaps, which has reduced processing time by over 95 percent.

“Before Collide, I'd spend hours manually keying in filings,” Buck Crum, director of operations, said in a news release. “(In March), we had 50 wells to file and I was done in 20 minutes. It does the majority of the heavy lifting while keeping me in control. That human-in-the-loop approach saves meaningful time and gives us greater confidence in our compliance and reporting.”

Collide was originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing.” After raising $5 million in seed funding led by Houston’s Mercury Fund last year, the company said it would shift its focus to rolling out its enterprise-level, AI-enabled solution.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
