Description
- The field covers an area of approx. 14 km x 7 km and contains two disconnected condensate gas reservoirs of Eocene to Late Miocene age. Elk-Antelope reservoirs are separated by a major thrust, with combined initial gas in place ranging from 6.2 to 7.5 Tcf of gas with the Antelope structure accounting for about 95% of the resources.
- The development strategy proposes the construction of 2 well pads with up to 12 wells, a Central Processing Facility (CPF), separate single phase gas and condensate evacuation pipelines and 2 liquefaction trains.
- The fields will provide gas to the Papua LNG Terminal Project
