Multistage Hydraulic Fracturing With Horizontal Wells In Unconventional Reservoirs (Study Case: Timimoun Field IRS-A Well)

Abstract

Abstract: Multistage hydraulic fracturing using horizontal wells has been an integral part of unconventional reservoirs exploitation because of their specific characteristics. The process uses long horizontal wells divided into many stages; Fluids are pumped down into each stage to generate a fracture, which increases the permeability of the formation to allow economic resource extraction. Reaching these results requires an optimal designing of the hydraulic fracturing treatment where we obtain the optimal treatment parameters in order to maximize the production with some constraints such as the cost and treatment capability. This thesis provides a guide for a better fracturing treatment design, with a study case where we reach the required design and improve the productivity in tight reservoirs. Keywords: unconventional reservoirs, hydraulic fracturing, horizontal wells, multi-stage fracturing, treatment design.
