The company, through its wholly owned subsidiary Marathon International Petroleum Indonesia, is the operator and holds a 70% working interest in the Bravo-1 well.
The well was drilled in a water depth of approximately 3,200ft and reached a total depth of 9,000ft.
Gas shows were recorded during drilling of the objective reservoir interval; however, the analysis of log and pressure data indicates the reservoir to be water-wet, the company said.
Both the thickness and quality of the reservoir encountered are encouraging and the well results confirm the pre-drill geologic model predictions.
The company intends to record a dry hole expense of approximately $60m for the Bravo-1 well in the fourth quarter of 2010.
The Romeo prospect, located on the north-central portion of the Pasangkayu block, is expected to be drilled during the first half of 2011.
Marathon holds approximately 1.8 million net acres (3.3 million acres gross) across the Pasangkayu, Bone Bay and Kumawa blocks in Indonesia.
Marathon is an integrated international energy company engaged in exploration and production; oil sands mining; integrated gas; and refining, marketing and transportation operations.
