Kistos Holdings plc has secured legal ownership of blocks 3 and 4 onshore Oman, purchased from Mitsui E&P Middle East B.V.
The company said it had received confirmation by royal decree from the Sultanate, and expects to complete the sale and purchase shortly, while acquisition of block 9 continues to progress.
Kistos signed the $148 million binding agreement for the three blocks in December 2025, with an effective date of 1 January 2025, adding 25.6 million barrels of oil equivalent of 2P reserves.
Blocks 3 and 4 comprise seven producing fields covering around 29,000 km² in eastern Oman, and block 9 covers two producing areas.
Omani company CC Energy Development and Texas-based Occidental Petroleum and operate each acquisition, respectively.
Executive chairman Andrew Austin said: “Royal decree on blocks 3 & 4 marks Kistos’ official entry into the MENA region, with the overall transaction with Mitsui in Oman doubling the company’s current production and 2P reserves, providing geographical diversification to our portfolio and a platform for further growth.”
Kistos additionally owns interests offshore the UK and Norwegian North Sea, and offshore the Netherlands.
