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 5):
An apparatus for recovering unconventional or conventional hydrocarbons from a formation, comprising:\n an existing multiple transverse fracture horizontal well (MTFHW) having associated existing primary transverse fractures; a first infill injection horizontal well having a casing, a cemented annulus, a drilled hole diameter, and associated first injection fractures, wherein the first injection fractures are half as long as the existing primary transverse fractures; and a second infill injection horizontal well having a casing, a cemented annulus, a drilled hole diameter, and associated second injection fractures, wherein the second injection fractures are half as long as the existing primary transverse fractures, 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, 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, wherein the first and second injection fractures are centered between the existing primary transverse fractures that intersect with the first and second infill injection horizontal wells, and wherein cement penetrates into the existing primary transverse fractures that intersect with the first and second infill injection horizontal wells to seal the cemented annulus between the casing and the drilled hole diameter of each of the first and second infill injection horizontal wells.
