Anadarko Sees More Pay in Mozambique

Wednesday, July 31, 2013

Anadarko Petroleum saw mixed results off the coast of Mozambique with the drilling of a few wells. One was a hit and the other was a miss. The company’s discovery was made with the drilling on the Espadarte prospect in Area 1. The Espadarte well encountered net gas pay of 280 ft in Oligocene and Miocene sands.

The well was drilled to a depth of 11,640 ft in a water depth of 1,536 ft.

The Espadarte-1 exploration well targeted an exploration play in the Miocene and the up-dip extent of Oligocene-aged reservoirs found at the Golfinho/Atum fields. The well encountered approximately 50 net ft of natural gas pay in Miocene reservoirs and 230 net ft of natural gas pay in Oligocene reservoirs.

The company said that pressure data indicate the Oligocene sands are in static communication with the Golfinho/Atum reservoirs, confirming this as a northwest extension of the field. Anadarko plans additional appraisal wells to fully evaluate the northern and up-dip extent of the Golfinho/Atum Field.

The company also said that subsequent to the close of Q2 its Atum-3 well encountered approximately 230 net ft of natural gas pay and established gas-water contact for the greater Golfinho field. This down-dip, appraisal well confirmed both separation from the Prosperidade field and an accumulation that lies entirely within Offshore Area 1.

The gas pay did not stop there for Anadarko during Q2, it also saw a discovery on the Orca prospect, as previously reported on Additional appraisal wells are planned for later in 2013.

While the company saw a significant amount of success since the outset of 2013, not all of its wells were a success. One of the last wells drilled, the Linguado-1, in northern Offshore Area 1 reached total depth during Q2 and was plugged and abandoned. While the well encountered thick, well-developed sands in the Miocene target, they were water-bearing.

In addition the company reported that it and ENI, the operators of Offshore Area 1 and Offshore Area 4 respectively, are progressing the Plan of Development for Prosperidade field. The plan is expected to be submitted to the government by the end of 2013.
