Abstract
Jangkar-1X was drilled in the first quarter of 1998 and discovered oil and gas in five reservoirs in the Lower Gabus and Pasir Formations. The Jangkar Field is located in the Kakap PSC (Indonesia) and is part of the Wrench Fault Trend which has yielded significant rewards to the Kakap PSC partners. The well was not tested but open hole log evaluation, down hole fluid samples and pressure data confirmed the presence of oil and gas in highly porous and permeable sands. In response to this success, a fast track development plan was formulated which resulted in a second well, Jangkar-2X being drilled, completed and placed on production as a sub-sea oil producer prior to the end of 1998. This fast track development was the result of a strategic decision to pre-purchase the long delivery items required for sub-sea tie-ins in anticipation of a least one successful exploration well in a multi-well drilling program. This paper reviews the basis for the decision to pre-order inventory and documents the strategy and development plan which resulted in this well being placed on production within ten months of the field being discovered as well as the technical and commercial results of the project.
