1. A gravity assisted reservoir drainage system, which comprises:
a plurality of preexisting horizontal wells, wherein each preexisting horizontal well is located within a respective stimulated reservoir volume created during its completion and which includes at least one non-overlapping hydraulic fracture;
at least one overlapping hydraulic fracture fluidly connecting at least one of the plurality of preexisting horizontal wells to an adjacent one of the plurality of preexisting horizontal wells; and
a new well, wherein the new well is completed within a stimulated reservoir volume containing the at least one overlapping hydraulic fracture after completion of the plurality of preexisting horizontal wells and includes a hydraulic fracture fluidly connecting the new well and at least one of the plurality of preexisting horizontal wells connected by the at least one overlapping hydraulic fracture.
