Inclusion propagation by casing expansion giving rise to formation dilation and extension

摘要: The present invention is a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by initiating propagating vertical permeable inclusions in plane substantially orthogonal to borehole axis. These containing proppant are thus highly enhance drainage heavy oil formation, also steam injection into these planes, heating sand bitumen, which will drain under gravity be produced. Multiple propped constructed at various locations along horizontal wellbore dilation formation intended inclusion radial expansion axial extension an expanding packer system that expands both radially axially. In another embodiment invention, device part casing string or liner contact with swellable elastomer, cement polymer based grout. expanded inflatable outward extensionally direction, giving rise dilated extensional well bore Injected fluid propagates preferentially this within formation.
