Paper presented at the Tight Gas Completions Conference, November 2–3, 2010
Paper Number: SPE-132541-MS
... Abstract Producing natural gas from Tight Gas Sand (TGS) reservoirs will be of increasing importance to the global energy industry in the coming decades. One of the basic decisions concerning the development of TGS reservoirs is to determine the size of the production casing and tubing. Because...
