The Cost of Gas Production Optimization Using Linear Programing on Reverse Fishbone Diagram: A Case Study
This paper presents the outcome of our research on the cost of gas production optimization in an oil field. To estimate the cost of gas redistribution, the following observations were arrived at: Gas storage/reinjection take priority, if the production goal is geared towards boosting the reservoir. Export Sales Gas is prioritized over Gas Lift Gas, on condition that maximum profit derivation becomes the essence for the gas production. Gas redistribution modes were formulated, and the following results were derived: alternate gas cost $152.076 (average per week) and fuel gas cost at $124.062 (average per week) for the period under review. While Diesel fuel cost at $2000 per day. The ratio of fuel gas usage was also compared with alternate fuel gas (diesel fuel) per day, which stood at 1:128 approximate. It indicates that diesel fuel usage cost one hundred and twenty-eight times (128) higher than the cost of average fuel gas usage per day.
