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 6):
A method for enhancing recovery of tight oil, condensate, or conventional oil from a formation, comprising:\n drilling and cementing a central horizontal well in a well direction that is not parallel to a maximum horizontal stress direction of the formation; fracturing the central horizontal well to provide central well transverse fractures; drilling a first horizontal well and a second horizontal well, wherein the central horizontal well is located between the first and second horizontal wells, wherein the central horizontal well is separated from each of the first and second horizontal wells by a specified distance, wherein the first horizontal well, the central horizontal well, and the second horizontal well are substantially laterally parallel, wherein the central well transverse fractures have half-lengths substantially equal to twice the specified distance; detecting locations of central well transverse fractures and cementing detected fractures to prevent hydraulic contact with the central well transverse fractures; casing and cementing the first horizontal well and second horizontal well, wherein cement penetrates into the central well transverse fractures intersected by the first horizontal well and second horizontal well to seal an annulus between a casing and a drilled hole diameter of each of the first and second horizontal wells and to prevent hydraulic communication between the first and second horizontal wells and the central well transverse fractures; fracturing the first horizontal well and the second horizontal well to provide first well transverse fractures and second well transverse fractures, wherein the first well transverse fractures and the second well transverse fractures are positioned such that each first and second well transverse fracture is located between two adjacent central well transverse fractures, wherein the first well transverse fractures and the second well transverse fractures have half-lengths substantially equal to half the length of the half-lengths of the central well transverse fractures, and wherein the central well fractures do not intersect the first well transverse fractures or the second well transverse fractures; monitoring pressure in the central horizontal well during hydraulic fracturing of the first horizontal well and the second horizontal well to detect unintended intersection between first well transverse fractures or second well transverse fractures with central well transverse fractures; and plugging detected intersections between first well transverse fractures or second well transverse fractures and central well transverse fractures.
