A month after the largest proppant placement in the history of hydraulic fracturing, the word from Limestone County, Texas, is encouraging. Massive hydraulic fracturing may be an economically viable approach to the tight, impermeable, gas-bearing Cotton Valley lime. As cleanup and testing continued in the closing days of 1978, Mitchell Energy's Muse-Duke No. 1 was flowing approx. 6.5 mmcfd of gas and 70-plus bbl of water through 20/64-in. choke. There were strong indications that about one-half of the well's perforations were sanded off and that cleaning them out to determine the well's true capabilities might require a workover job. While tests during the ensuing month have been encouraging, it may be another 2 mo. or longer before Mitchell and DOE know many of the things they need to know to determine orientation and extent of the fracture, the effect on well productivity, and the economic merit of what they have done.
