Marathon Oil has drilled the deepwater Bravo-1 well offshore the island of Sulawesi in the Makassar Strait, Indonesia, to a total depth of 9,000ft.

The well, which was drilled in a water depth of 3,200ft in the north-east portion of the Pasangkayu production sharing contract area, recorded gas shows in the reservoir interval, although the reservoir is indicated to be water-wet.

The firm claimed that the thickness and quality of the reservoir encountered are encouraging and the well results confirm the pre-drill geologic model predictions.

Marathon plans to record a dry hole expense of $60m for Bravo-1 in the fourth quarter of 2010.

Marathon subsidiary Marathon International Petroleum Indonesia is the operator of Bravo-1 and holds a 70% working interest in the well.
