Applying reserve/production ratio to calculate rational production well quantity in Gudong Oilfield

The determination of rational production well quantity in oilfield and infill potential analysis were too complicated, technical advices on infill well pattern was summarized in this paper based on statistics of infill well pattern in Gudong Oilfield. Firstly, the annual oil production of new infilling wells is double of average production of old wells. Secondly, incremental recoverable reserve of new infilling well is 10 times of average annual oil production of old wells. Thirdly, determine annual production when reserve/production ratio is 5. And then method of using reserve/production ratio to calculate rational production well quantity is proposed by this paper, and it's proved effective by the application to Kendong 32 Block. The use of reserve/production ratio to Gudong Oilfield has been also introduced in the paper, and infilling wells are calculated as well as rational production well quantity, which provide references to infilling adjustment in the future.
