Technique for determining volumetric parameters derived from production logging data to estimate West Siberian oil fields reserves

Key words: volumetric parameters, reservoir, porosity, oil saturation, bulk volume water (BVW), residual water saturation.

Conventional and advanced methods for distinguishing oil reservoirs, estimating oil porosity and oil saturation factor of reservoirs in the Middle-Ob’ region are presented. The methods are based on detailed production log data and drill core study results. They are used for oil fields in the Middle Ob’ region and Shaim petroleum-bearing area. These methods approved by the State Reserves Committee are successfully applied to estimate oil reserves.
