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)

The problem of optical design is stated as follows: Given a principal surface r($alpha$), and a maximum focal angle $alpha$/sub m/, find the pair of optical surfaces for which diffraction limited focusing is achieved. It is shown that specification of r($alpha$) and $alpha$/sub m/ uniquely determines the lens design to within a scale factor, given the refractive index of the lens. It is further shown that one straightforward Runge-Kutta integration routine generates both surfaces for either a lens or a pair of mirror surfaces. The complete family of aplanatic lenses is described. Deviation from sphericity is discussed, as well as the possibility of realizing the specified lens designs. The family of lenses which map uniform incident intensity into uniform illumination about the focus is also described. Extension of the method to off-axis aberrations is considered. (auth)
