... Abstract Decline analysis using Arp's equations is the primary empirical method used in the petroleum industry for estimating future reserve recovery and generating production forecasts. The development of tight gas and in particular shale gas reservoirs as important new sources of gas...

... investigation of CBM decline is warranted. Before investigating the decline behavior of CBM wells, the literature on conventional gas decline analysis is summarized and the factors affecting production performance are discussed. The production performance of CBM is then investigated and compared...

... grouping. The forecasted remaining recoverable reserves will be compared to the known remaining recoverable reserves to evaluate these statistical forecasting methods. Economic evaluations will also be run for each of the scenarios discussed. Introduction Decline analysis using the Arps 1 exponential...

... Abstract Decline analysis and reserves estimation based on decline analysis should be fundamentally grounded in a good understanding of what factors control the decline.The same decline techniques cannot, and should not, be applied to all fields and all drive mechanisms. Specifically...

... Abstract Decline analysis is the most used technique for forecasting reserves. Although decline analysis for gas fields has been shown to have a strong theoretical background, decline analysis for multiphase situations is less clear. This paper suggests when it is appropriate to use decline...
