The Week in Energy – Oct. 3, 2025

byEnverus

This week’s energy headlines are packed with strategic divestments, offshore breakthroughs and infrastructure growth across the Americas and beyond. Here are the top stories shaping the market: 

  • Occidental Petroleum sells OxyChem to Berkshire Hathaway for $9.7 billion. The deal will help Occidental reduce its debt below $15 billion and save over $350 million annually in interest expenses. 
  • BP greenlights its Tiber–Guadalupe oil project in the Gulf of Mexico. The new platform will unlock 350 million barrels of recoverable resources and produce up to 80,000 bo/d.  
  • LLOG Exploration starts production at the repurposed Salamanca facility. This marks the first time a Gulf of Mexico platform has been refurbished and returned to service, boosting offshore efficiency. 
  • Targa Resources expands in the Permian Basin. Three new projects—Speedway NGL pipeline, Yeti processing plant and Buffalo Run gas pipeline—will enhance basin-wide capacity and connectivity. 
  • Tourmaline Oil sells royalty interests to Topaz Energy for C$72 million. The deal covers 134,000 Montney acres and supports Tourmaline’s long-term growth strategy.
