Optimizing the Development of Tight Reserves of the V. Vinogradov Field using Multi-Stage Hydraulic Fracturing

Abstract

The work describes the implemented techniques which help optimize reservoir engineering for tight oil deposits with the usage of multi-stage hydraulic fracturing by up-to-date methods of fracturing values’ evaluation. The work also identifies reasons of high water cut of well production after the multi-stage hydraulic fracturing at the V. Vinogradov field. The work also describes principles of preparing and implementing the optimum design of the multi-stage hydraulic fracturing under the conditions of unconstrained growth of the vertical component of the hydraulic fracture without any restraining barriers. After the set of operations, the quality of hydraulic fracture control increased and the well production water cut reduced.

A multi-perforation staged fracturing experimental study on hydraulic fracture initiation and propagation

“…Many studies related to multi-stage fracturing in thick tight sandstone reservoirs have been conducted (Karpov et al., 2017; Li et al., 2018; Lu et al., 2015; Olson and Taleghani, 2009). Olson and Taleghani (2009) suggested that hydraulic fractures could propagate across natural fracture planes without deviation and without additional leak-off under certain conditions.…”
