    Abstract: A method for manipulating hydraulic fracture geometry. In one embodiment, the method comprises injecting a fracturing fluid into a well to generate one or more hydraulic fractures in a subsurface rock formation and then substantially draining any fluids from the one or more hydraulic fractures. The method may further comprise injecting a hydrophilic polymer and one or more crosslinking agents into the well to subsequently form low-density hydrogels which may then screen out only each tip of the one or more hydraulic fractures. A working fluid may then be injected into the well to increase fracture width of the one or more hydraulic fractures without substantially increasing fracture length. In an alternative embodiment, the hydrophilic polymer may be fully crosslinked by the one or more crosslinking agents and injected as pre-formed particle gels (PPGs) which may also screen out only each tip of the one or more hydraulic fractures.

    Abstract: A method for improved borehole completion. In one embodiment, the method comprises removing a section of casing entirely and cutting a notch through the cement and into the surrounding rock formation, wherein the notch optimally comprise a symmetric triangle terminating in a sharp point oriented perpendicular to the casing axis. Flow may be further optimized by extending the notch as far as practical into the rock matrix to increase the effective diameter of the wellbore and increase the length of the intersection between the fracture and the wellbore.
