the arkla exploration t.p. scott no. 5 in waskom field, harrison county, texas was drilled in may 1986. the well was cored and logged in the travis peak formation, and, using the gri mobile testing and control facility, the authors monitored the pre-fracture test and the fracture treatment in the cotton valley formation. they combined the analyses from gri's contractors and summarized their work in the travis peak as well as using their results in the analysis of the cotton valley completion. a low resistivity sandstone was identified as possibly the best candidate for testing in the travis peak petrographic analyses indicated that clay cutans surrounding the sand grains were probably causing the low resistivity rather than high water saturation. despite a short flow period and a short shut-in period, an estimate of permeability-thickness could be obtained from the buildup test in the cotton valley completion. however, because only a small portion of the perforations appeared to be open, the exact intervals that were producing and the corresponding net gas pay could not be identified. fracture length was estimated from fracture design models and simulation of the post-fracture production of the well. these results are discussed in detail in the report
