Abstract

Tyumen suite deposits of the field T are referred to continental and subcontinental deposition environment and characterized by significant facial variety, high lateral heterogeneity and irregularity of geological bodies. Field - geological analysis of reserves recovery and development current status is conducted using traditional methods on the basis of regions, distinguished as a result of deposit dividing into waterflooding blocks and cells. Such approach do not take into account complex details of field geologic structure, therefore definition of blocks, bounded by facies and injection wells, is suggested. Subsequently, comparison of current and cumulative well performance and reserves recovery in different facial blocks is necessary. On the basis of constructed plots recommendations for the future development optimization of certain blocks should be given. The next aim is definition of geological heterogeneity parameter as a relationship between sweep efficiency coefficient and stream tube length for different facies. Thereafter, on the ground of these functions, select the most effective parameters of approved development system for undrilled areas in the context of technologic and economic performance.
