Abstract:
Enhancing the recovery of unconventional and conventional hydrocarbons is possible by utilizing patterns of wells and hydraulic fractures that are carefully designed to avoid interconnection between injection and production well fractures to allow for both primary production and improved secondary production. Adjacent horizontal wells may be drilled and fractured, with selected wells converted to injection wells after primary production to produce alternating production and injection fractures. In addition, infill horizontal injection wells may be drilled and fractured adjacent to an existing and previously produced multiple transverse fracture horizontal hydrocarbon production well to produce alternating production and injection fractures.

Claim (Index 1):
A method for enhancing recovery of unconventional or conventional hydrocarbons from a formation having an existing multiple transverse fracture horizontal well (MTFHW) and existing primary transverse fractures associated with the multiple transverse fracture horizontal well (MTFHW), comprising:\n drilling a first infill injection horizontal well and a second infill injection horizontal well, wherein the existing multiple transverse fracture horizontal well (MTFHW) is located between the first and second infill injection horizontal wells, wherein the existing multiple transverse fracture horizontal well (MTFHW) is separated from the first and second infill injection horizontal wells by a distance of half of a half-length of the existing primary transverse fractures, and wherein the first infill injection horizontal well, the existing multiple transverse fracture horizontal well (MTFHW), and the second infill injection horizontal well are substantially laterally parallel; determining locations of the existing primary transverse fractures associated with the existing multiple transverse fracture horizontal well (MTFHW) that intersect with the first and second infill injection horizontal wells; casing and cementing the first and second infill injection horizontal wells, wherein cement penetrates into the existing primary transverse fractures intersected by the first and second infill injection horizontal wells to seal an annulus between a casing and a drilled hole diameter of each of the first and second infill injection horizontal wells and to prevent hydraulic communication between the first and second infill injection horizontal wells and the existing primary transverse fractures; hydraulically fracturing the first and second infill injection horizontal wells at perforation cluster locations centered between the existing primary transverse fractures that intersect with the first and second infill injection horizontal wells to produce first injection fractures and second injection fractures; monitoring pressure in the existing multiple transverse fracture horizontal well (MTFHW) during hydraulic fracturing of the first and second infill injection horizontal wells to detect direct intersection between first and second injection fractures and existing primary transverse fractures; plugging detected direct intersections between the first and second injection fractures and the existing primary transverse fractures; injecting secondary recovery fluids into the first and second infill injection horizontal wells; and producing secondary hydrocarbons from the existing multiple transverse fracture horizontal well (MTFHW).
