Method for design of production wells and injection wells
Abstract:
The disclosure claimed herein relates to well systems for various fluids production, in particular, for production of fluids from hydrocarbon-containing formations using hydraulic fracturing process. According to the proposed method, injecting into well of fracturing fluid not containing proppant is performed to form a fracture in the formation, after which fracturing fluid is injected into the wellbore in pulse mode; the pulse mode provides at least one pulse of injecting fracturing fluid containing proppant, and at least one pulse of proppant-free fluid. Also, methods for fluid production and injection are proposed. Methods for fluids production, injection and recovery using hydraulic fracturing method are proposed. The proposed method increase the well lifetime due to reduced fluid flow impact on fracture walls and proppant clusters.
