Well surveys with jet pumps after hydraulic fracturing

Abstract

Hydraulic fracturing (HF) is successfully used all over the world and allows to increase the efficiency of the well, as well as to put into operation wells with plugged bottomhole zone. Service companies every year pay more and more attention to hydraulic fracturing and the promotion of new solutions to further increase the efficiency of this technology, which contributes to its importance in the stimulation of production. The main advantage of hydraulic fracturing is to increase the drainage area of the reservoir, and especially when performing multi-stage hydraulic fracturing (MSHF). Violation of the induction stimulation technology after hydraulic fracturing can lead to proppant blowback not only at the development stage, but also at the well operation stage. One of the solutions to prevent such complications is the use of jet devices, which make it possible to fix the proppant in the fracture and reduce the well development period. The article investigates the results of hydrodynamic studies of wells with jet pumps. Various forms of indicator diagrams are given and their description is made. The method of calculation of reservoir parameters by pressure build-up has been studied. The results of data processing of hydrodynamic studies by a jet pump are presented
