NEW METHOD OF CALCULATING THE CONTRIBUTION OF OIL WELL STIMULATION TREATMENTS ON PRODUCTION INCREASING

Decision making of oil well stimulation treatments is very important in world oil reservoir management, however the present method on calculating the oil production increment exhibits some defects and cannot reflect the real production increasing. A new method is present here which takes the correlation between the stimulation treatments implemented on different date into consideration, and oil production increment in any time period can also be analyzed. The calculation of production increment in June 2002 of Dagang Oilfield is taken as an example, and it shows that the new method is subjective and can reflect the actual effects and economic benefits produced from stimulation treatments.
