Technical and Economic Evaluation of Oil reservoirs in The Form of Optimal Management of Reservoir Development (Case Study of Asmari reservoir in One of Iranian southwest Oil Fields)

Technical and economic evaluations in an oil field means that by different technologies and correct planning, maximize the amount of extraction of hydrocarbons and minimize risks and costs. The current research includes technical evaluation and economic analysis on one of the undeveloped reservoirs in the southwest of Iran. The amount of recoverable hydrocarbon was estimated using the Monte Carlo method and based on the dynamic modeling of the oil reservoir, economic modeling was applied. Among the scenarios defined for the development of the reservoir, the most compatible scenario that has the highest rate of recovery of the reservoir and the best economic indicators has been selected as the best development scenario. In this scenario, production from the oil reservoir by drilling 14 new wells in 14 years and maintaining a maximum production rate of 10,000 barrels per day in order to produce 430 million barrels of oil and a recovery factor of 29.7% with total final cost of 0.995 billion dollars and The cumulative current value is 136.2 billion dollars. Investing in small, undeveloped reservoirs based on detailed analysis of performance and economic indicators can be very profitable and help to maintain the vital resources of the country.
