Abstract
The invention is a method of producing hydrocarbons from a region bounded by two vertical wells and a horizontal well, which comprises injecting a gas through a first vertical well, concurrently performing a cyclic injection, soak and production of gas through a horizontal well, converting the first well to production after the gas injected from the first well reaches the area affected by gas from the horizontal well, and injecting gas through a second vertical well.
