Abstract:

 

Unwanted water and gas production in producing wells negatively impacts the productive life of the wells and the reservoir itself. As more and more reservoirs are maturing, the urgency to develop methods to control unwanted fluid production, and thus to improve the recovery efficiency of the wells and the reservoirs is imperative. Many negative effects that occur during production such as high WOR and GOR, scaling, and skin damage can be pro-actively prevented during drilling by using new and emerging Conformance While Drilling (CWD) technology and thus can facilitate to shut off future water and gas influx.

 

This presentation will focus on the new and emerging solutions to the challenging conformance problems using processes, chemical systems, techniques, tools, and real time predictive methods and software to derive successful water and gas shut-off solutions for both vertical and horizontal wells. Water shut-off problems and solutions for more challenging open-hole horizontal completions using the emerging chemical and swell packer systems and placement techniques based on the reservoir understanding of the problems will be discussed. Critical factors for developing a successful conformance solution and a water management strategy will be identified. Real life field case histories in deriving successful conformance solutions will be presented.
