We carried out the upstream section of a gas utilisation study designed to establish if the implementation of an early gas power generation scheme in the license area was technically and economically feasible. We developed a reservoir simulation model for the discovered fields and established a field development plan for the production of gas suitable for power generation.The plan included a scheme to recover associated liquids and to produce LPG for local consumption. We carried out costing and economic analysis of the upstream scheme to establish the optimum production scheme. The development and operating costs were generated using our NETCO$TER cost Evaluation Software.
