Combined technological solutions to increase inflow in oil wells of offshore fields

Abstract

Hydraulic fracturing (HF) technology is widely used all over the world. It enables to increase the efficiency of a well and put into operation wells with clogged bottomhole zone. Annually, service companies pay much attention to HF and promote new solutions to improve the efficiency of this technology, which contributes to its importance in stimulation of production. The main advantage of HF is the increase in the drainage area of a reservoir while multi-stage hydraulic fracturing. It is shown that HF and violation of the inflow stimulation technology can lead to proppant backflow not only at the stage of well development, but also during well operation. One of the solutions to prevent such complications is the use of technical means that provide proppant attachment in the fracture and reduction in the time of well development. The paper proposes technological and technical means to improve reservoir-to-well connectivity, to increase reservoir area covered by the fractured space, to reduce material and time costs during well development. It is shown that combined technological solutions for HF and well development lead to an increase in the flow rate of oil wells.
