METHOD FOR OBTAINING HORIZONTAL FRACTURES IN AN OIL RESERVOIR", ABSTRACT OF THE DISCLOSURE A closed pattern of wells is completed in an oil reservoir which is characterized by a tectonic stress regime conducive to vertical fracturing. Fluid is injected into the outlying wells of the pattern at sufficiently high pressures to create vertical hydraulic fractures at these wells. Thus pressure is applied to the reservoir from the corners of the pattern inwardly, to alter the stress regime to one conducive to horizontal fracturing. The central well is then subjected to fluid injection while pressure is maintained on the outlying wells,to generate a horizontal fracture system emanating from the …
