Abstract: This paper presents a new method for determination of reserves controlled by single well in unsaturated oil reservoir. From pseudo steady state percolation equation, single well-controlled reserves can be determined easily through simple derivation of the method. With this method, shut-in pressure is unnecessary. Only dynamic data such as stage daily production and cumulative production and initial reservoir pressure and bottom-hole pressure are required. Through linear regression and extrapolation, single well-controlled reserves are attained. The case study shows that the reserves determined by this method are well close to the static single well reserves. Therefore, this method is simple, applicable, accurate and reliable.

Key words: unsaturated oil reservoir, oil well, controlled reserve, percolation
