Comparison of two Devonian Shale wells: why is one well better than the other? Conference Paper uri icon

abstract

  • This paper summarizes the detailed analysis of geological, geophysical, geochemical, and well test data from three Devonian Shale and Berea sand wells located in Pike County, Kentucky. These three wells were part of a Gas Research Institute (GRI) project designed to gain a better understanding of the producing mechanisms of the Shales and Berea and the impact of stimulation on well performance. All three wells were completed in both the Shales and Berea, which is typical for the area. Detailed data were collected in both the Shales and the Berea on two of the three wells which were used to develop layered, naturally fractured reservoir descriptions for each producing horizon. Each formation was stimulated with nitrogen foam and sand fracture treatments, and in general, the pre- and post-stimulation well performance was similar to predictions made using the layered, naturally-fractured reservoir descriptions. This paper compares these reservoir descriptions and provides a technical basis for the widely varying production often observed with Shale and Berea wells in this region.
