US-based integrated oil company Marathon Oil has announced that its subsidiary, Marathon International Petroleum Angola Block 32 Limited, has participated in the new deepwater discovery, known as Alho, on Block 32 offshore Angola.

Alho is the 11th discovery on Block 32 and the 26th overall discovery in Marathon’s deepwater exploration program on Blocks 31 and 32, which began in 2001.

The Alho-1 discovery well is located approximately 155 kilometers off the Angolan coast in 1,607 meters of water. The well was drilled to a total depth of 4,981 meters and encountered oil bearing reservoirs in the Oligocene section.

According to the company, the well flowed at a rate of 5,400 barrels per day during drill stem testing. Alho is located nine kilometers northwest of the previously announced Cominhos discovery.

The concessionaire of Block 32 is Sonangol, Angola’s state-owned oil company. Marathon holds a 30% interest in the block, along with the operator Total Exploration and Production Angola with 30%, Sonangol P&P with 20%, Esso Exploration and Production Angola with 15%, and Petrogal with 5%.
