Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas
A proposed two-well stimulation test to be carried out in Sutton County, Texas is described. Work will be performed in the lenticular tight sand formation of the Val Verde-Kerr Basin to demonstrate the technical and economic feasibility of chemical explosive fracturing as a method of increasing gas deliverability in that formation. The purpose of the project's experimental design, which calls for the testing of two separate wells using different techniques, would be to obtain the maximum amount of information relating to the most effective method of stimulating this particular reservoir. Results will permit the direct comparison of the different completion techniques. Also the testing of more than one well in a given area will allow for the collection of complementary data with regards to the characteristics of the reservoir and the experimental results from the explosive stimulation. The environmental effects of the project are assessed. (JRD)

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas
The Nevada Operations Office of the Energy Research and Development Administration (ERDA) has contracted with Petroleum Technology Corporation (PTC) to perform a gas stimulation program by chemical explosive fracturing (CEF) in the Canyon sands of the Val Verde - Kerr Basin of Sutton County, Texas. This lenticular tight sand deposit, underlying much of southwestern Texas, contains large volumes of natural gas. To date this formation has yielded only marginal amounts of gas because of its low porosity and permeability. The semi-arid environment of the Aldwell/Sawyer field is characterized by dry arroyos and xeric vegetation. Population is sparse and sheep ranching is the primary occupation. Because of the existence of previously drilled oil and gas wells, road and pipeline construction will be minimal. Impacts from this two well project are expected to be minimal and be confined to temporary surface disruption and increased erosion at the well site.
