In early July 2026, Parex Resources completed a $750 million acquisition of Frontera Energy, a move that immediately increased its oil output in Colombia. By the end of July, the company deepened its involvement in the country by signing a five‑year, $250 million collaboration agreement with state‑owned Ecopetrol. The deal targets the Casabe, Casabe Sur, Peñas Blancas and Llanito fields in the Magdalena Medio region, focusing on enhanced oil recovery, water‑injection optimization, new wells and exploratory work. The partnership coincided with Ecopetrol reporting a 96 % jump in second‑quarter 2026 net profit, driven by higher Brent prices and improved refining margins, and came shortly after a leadership change at the state oil firm.
