Evaluating the Benefits of Tight Gas Sands Research. Part 1. Parametric Study toEvaluate Benefits of Fracture Fluid Quality Control and In-situ Stress Research. Topical Report, August 1990

摘要

The study was conducted to evaluate the economic benefits of GRI's tight gassands research devoted to the quantification of in-situ stresses and the understanding of fracture fluid rheology. A base case data set was defined and used to investigate the effects of in-situ stress contrast, fracture fluid viscosity, formation gas permeability, and pay zone thickness. Using incremental values of gas recovery, plus the costs for performing and applying technology in the field, a series of graphs were generated which illustrate the benefits of applying modern technology when fracturing a gas well.
