Evaluation of rational bottom-hole pressure for oil deposits with high gas saturation

Authors: V.V. Poplygin (Perm National Research Polytechnic University, RF, Perm), , I.S. Poplygina (PermNIPIneft Branch of LUKOIL-Engineering LLC in Perm, RF, Perm)

Key words: oil reservoir, bottom-hole pressure, reservoir pressure, productivity index, well, oil recovery.

The article regards how wells productivity changes during the Visean deposits development when the reservoir and bottom-hole pressures vary. For Bobrikov objects of oilfields in the north of Perm region, the duration of recovery of 70 % of the initial recoverable oil reserves is calculated in the conditions of existing development systems and different values of bottom-hole pressure using the program PrognozRNM. According to calculation results authors are defined bottom-hole pressures allowing recover 70 % of recoverable reserves within the shortest possible period of time.
