A Houston-based company that develops, produces, and decommissions mature assets in a cost-effective and environmentally sustainable manner and begun work on the temporary abandonment of nine orphan wells.

Promethean Energy has announced the beginning of the project on the wells on behalf of the Department of Interior's Bureau of Safety and Environmental Enforcement, or BSEE. The temporary abandonment of the nine wells, which are located in the Matagorda Island lease area in the Gulf of Mexico, is the first stage of full decommissioning of oil and gas infrastructure.

"We are very proud to have been able to start work and contribute to this project of strategic national importance commissioned by BSEE," Promethean's SVP Decommissioning Steve Louis says in a news release.

The company was awarded a five-year Indefinite Delivery/Indefinite Quantity (IDIQ) contract "to address the most immediate and urgent needs representing safety and environmental hazards" of the wells which no prior owner survives, per the release.

Promethean has conducted its own inspection of the platforms using drone-based laser scan technology in order to digitalize the structures and evaluate the equipment to plan safe boarding and procedures.

The next steps of decommissioning the wells will be to repair the platforms and wellhead equipment, followed by well diagnostics testing and the well decommissioning itself.

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
