Abstract
A method for in situ extraction of hydrocarbon materials in a subsurface region includes increasing permeability of a low permeability hydrocarbon-containing subsurface region to create a first well sub-region and a second well sub-region vertically below the first well sub-region. The first well sub-region is heated to extract liquid hydrocarbon materials that flow to the second well sub-region. The liquid hydrocarbon materials are then transported from the second well sub-region.
