Cleaning Up Water Blocking in Gas Reservoirs by Microwave Heating

Water blocking caused by fluid invasion during drilling, completion, and stimulation has been suspected of reducing or blocking gas-well deliverability. A technique that uses microwave heating to clean up water blocking in sandstone gas reservoirs is presented. Water-block cleanup by use of microwave heating is encouraging for field application, but further laboratory studies are required for the next phase of this project.
