We carried out a screening study for a small potential onshore development in Angola. The potential field had a recoverable reserve of 50 Million Barrels and was located below a lake in an inaccessible, swampy terrain in the south of the country. The study took special care to establish appropriate solutions for the terrain encountered and the remote location. The study was designed to assess the economic benefit associated with conducting an exploration program. The development and operating cost estimates were generated using our NETCO$TER cost Evaluation Software.
