We carried out a screening study for a medium sized onshore gas condensate field in Nigeria with reserves. The assessment focused on establishing the size and cost of facilities required for liquids production scenarios ranging from 30,000 through 50,000 barrels per day. The study was designed to establish the economic optimum production rate based on price constraints including restricted local market for sale of associated gas. The development and operating cost estimates were generated using our NETCO$TER Cost Evaluation Software.
