Complete Drilling and Completion Technology for Shale Gas Development

Abstract:

China is very rich in shale gas resources with great development potential. It is possible to form a series of complete drilling and completion technology for shale gas development through borrowing, converting and utilizing of wellproven conventional oil and gas development technology. Horizontal drilling has dominated the drilling methods for shale gas development, and integrated with rotary steerable drilling, MWD/LWD, 3-D seismic survey, and underbalanced drilling, it will increase development efficiency. Hydraulic fracturing is a main technique for stimulation of shale gas reservoirs. Advances in slick water fracturing, refracturing, synchronized fracturing, etc., will make shale gas development more promising.
