ABSTRACT:
A method of completing a horizontal well in an incompetent formation includes running a pipe string into the horizontal well bore, pumping a hardenable permeable material into the horizontal well bore, allowing the hardenable material to set up and then drilling up at least part of the pipe string. The hardenable permeable material may be resin coated sand providing sand control for the incompetent formation. In the event the horizontal bore hole vertically meanders out of a desired path and falls below an oil-water contact or rises above a gas-oil contact, that portion of the pipe string located out of the desired path is not drilled up thereby deterring production of undesired formation fluids.
