Despite some scatter in the data (due to the differences in how the wells are operated, completed, and maintained) a positive linear correlation was found between SWD well performance and permeable dolomite footage. Additionally, anhydrite is most abundant in the northeastern...

... as opposed to calcite and clays. Wang and Gale (2009) introduced a second desired parameter, dolomite, as another brittle component. The mineralogy concept of classifying rocks is very convenient to apply, as it only requires knowledge of rock's composition, accessible from logs or cuttings. Even more...
