Recovery of tight oil reserves related to thin under-gas rims complicated by a presence of bottom water represents a crucial task for a huge number of operators throughout the world.

The main problem of development of such reserves are represented by almost inevitable processes of gas and water coning leading to gas and water breakthrough to the bottom of producing wells which in its turn affects process and economic performance indicators of development and prevents reaching high oil recovery factor (ORF) values.

This article represents an efficient approach to recovery of tight oil reserves related to thin under-gas rims with bottom water providing for the use of multipurpose wells with complex design allowing efficiently using the gas cap energy and managing the risks related to water coning.
