Abstract

Abstract:

The methods for calculating the single well controlled reserves by pressure build up curve are mostly using time to calculate the single well drainage area, and then apply volumetric method to obtain single well controlled reserves. If the test data is undulatory or not determined, it will be hardly to get the single well controlled reserves. A new method forsingle well controlled reserves based on pressure is proposed, which can avoid the limits of the methods based on time. It uses Horner straight line to calculate the single well drainage area, and then obtain the single well controlled reserves. The practical application result proves the reliability and validity of this method.
