Anadarko Petroleum Encounters Hydrocarbon Pay in Jupiter-1 Discovery Well

Anadarko Petroleum has declared that it encountered 30 m of hydrocarbon pay present in Upper Cretaceous-age reservoirs of the Jupiter-1 discovery well, offshore Sierra Leone.

The company reported that the new appraisal well, Lagosta-3, located in offshore Mozambique returned around 176 m of natural gas pay in several zones.

According to Bob Daniels, Senior VP of Worldwide Exploration of Anadarko, the Jupiter-1 well has been possibly conserved for re-entry, as the region may need further assessment. The company is planning for a possible drill stem testing (DST) at the basin, after testing the Mercury appraisal well in order to provide further data regarding deliverability and quality of the reservoir.

The location of the Jupiter-1 well in block SL-07B-11 lies over 25 km from the Mercury-1 discovery well. The company drilled Jupiter to a depth of around 6,465 m totally in water depths of about 2,199 m in the Sierra Leone or Liberia basin. The rig will be mobilized to drill the Mercury-2 appraisal well, when the Jupiter operations are finished.

The company has 55% of working interest in the block and is the operator of the block. Tullow Sierra Leone with 20% and Repsol Exploracion Sierra Leone of 25% are the co-owners in the block.

Daniels added that the appraisal drilling of the partnership is continuing to authenticate and extend the nature of this immense accumulation of natural gas offshore Mozambique. The Lagosta-3 well returned sands with high-quality and validated the regions of the field. The company is continuously accelerating the functional learning curve, drilling the final two wells safely and quickly. Anadarko is expecting these developments in drilling efficiency in order to transform into cost savings, as the project is continually advancing.

The Lagosta-3 well lies approximately 3 km towards the west of the Lagosta-1 discovery well and 15 km towards the Camarão-1 well’s southern part. Drilling will be stopped, during the mobilization of rig to drill the Barquentine-4 well.
