(2015037) ELIMINATING CASING PATCHES AND RESTORING WELLBORE INTEGRITY - A SOLIDS FREE RESIN SYSTEM CAPABLE OF WITHSTANDING STIMULATION TREATMENTS
The development of horizontal drilling combined with hydraulic fracturing has allowed operators to develop unconventional shale plays once considered uneconomical. As operators move toward longer horizontal and multilateral sections in these plays, the complexity with respect to well stimulation and completion systems increases. Before a well is stimulated or completed, critical problems can emerge, such as casing leaks. Depending on the well configuration, traditional remediation methods might be unable to withstand stimulation treatments, difficult to apply and/or create a restriction in the casing inside diameter. This paper discusses how an acid and abrasion resistant resin system was applied to remediate a tight leak in the multi-stage cementing tool of a 5.5 in production casing and enabled the operator to pass a pressure test and carry out the planned stimulation of the well in twenty-five stages, without any signs of a leak.
