Abstract
Systems and methods for drainage of a heavy oil reservoir via a horizontal wellbore. A method of improving production of fluid from a subterranean formation includes the step of propagating a generally vertical inclusion into the formation from a generally horizontal wellbore intersecting the formation. The inclusion is propagated into a portion of the formation having a bulk modulus of less than approximately 750,000 psi. A well system includes a generally vertical inclusion propagated into a subterranean formation from a generally horizontal wellbore which intersects the formation. The formation comprises weakly cemented sediment.

A well system, comprising:
- a generally vertical first inclusion propagated into a subterranean formation from a generally horizontal first wellbore which intersects the formation, and
- wherein the formation comprises weakly cemented sediment.
A method of improving production from a subterranean formation, the method comprising the step of:
- propagating a generally vertical first inclusion into the formation from a generally horizontal first wellbore intersecting the formation, the first inclusion being propagated into a portion of the formation having a cohesive strength of less than a sum of 400 pounds per square inch and 0.4 times a mean effective stress in the formation at the depth of the first inclusion.
A method of improving production from a subterranean formation, the method comprising the step of:
- propagating a generally vertical first inclusion into the formation from a generally horizontal first wellbore intersecting the formation, the first inclusion being propagated into a portion of the formation having a bulk modulus of less than approximately 750,000 psi.
