Paper presented at the SPE Americas Unconventional Resources Conference, June 5–7, 2012
Paper Number: SPE-154981-MS
... recoveries in shale gas reservoirs requires new techniques. In this paper, we used four approaches to estimate the ultimate recovery in shale gas wells: two empirical methods (conventional and modified decline curve analysis), analytical modeling and numerical modeling. All four approaches were applied on...

..., linear, pseudo-radial, boundary dominated) are investigated. Finally, a methodology for applying traditional decline curve analysis to tight gas, with reference to long term transient flow, is presented. Introduction The goal of this work is to outline a method of production forecasting for tight gas...

... poorer producer may be the result of fracture depletion or the length of actual producing time (among other factors) rather than a change in reservoir quality. The use of matrix controlled production information, derived from decline curves, appears to resolve this problem. Introduction Columbia Gas...

Paper Number: SPE-10837-MS
... N. Central Expwy., Dallas, TX 75206. Abstract Several studies on production decline curves have shown that an exponential or hyperbolic curve adequately fits production decline data for Devonian shale wells. Attempts to characterize the production decline based on open flows, rock pressures, and...

... production decline curves, is presented for interpretation of low pressure, shallow (3,000 ft.) gas well reserves. A pilot study indicates benefits of the program to be (1) uniform method of analysis; (2) more accurate results; and (3) availability of the results for use in other computer applications...
