WebMar 3, 2011 · Water/oil ratio and cumulative decline curve. Figure 7-6. Water cut and cumulative decline curve. GOR—Cumulative Oil Production. Use of a rate-cum or WOR-cum analysis can be used to estimate periodic and ultimate GOR, which can then be converted to gas production. Conversely, if gas volume is a limitation on production … WebDecline curve analysis (DCA) is used to predict the future production of oil and gas, and it has been widely used since 1945. Arnold and Anderson (1908) presented the first mathematical model of DCA. Cutler (1924) also used the log-log paper to obtain a straight line for hyperbolic decline, so the curve shifted horizontally. Larkey (1925) proposed the …
