Qualified for the sixth cycle of the permanent concession offer (OPC6), scheduled for October 7, Perthro (Canada) Inc. is an independent oil company controlled by the Swedish Perthro AB, which is in the process of international expansion with a focus on low-cost onshore assets in North America.

In 2025, the company began operating as an operator by acquiring the oil-producing assets of Girouxville, in the Canadian province of Alberta, owned by Blacksteel Energy, marking the beginning of its growth strategy through acquisitions.

Kufpec registered for OPC6 and the fourth cycle of the permanent production sharing offer (OPP4). Founded in 1981, the company was created to develop oil and gas assets outside Kuwait and today maintains operations and interests in projects in Africa, the Middle East, Asia, Europe, North America, South America, and Oceania.

The Middle Eastern oil company entered the Brazilian market in 2026 by acquiring from Shell a 20% stake in the Orca project, in the Santos Basin pre-salt. After the completion of the transaction, Shell remained the operator with a 50% stake, while Ecopetrol kept 30%.
