| Abstract: | The mathematical expressions of Weibull peak shape development model have been established. They are that oilfield development indexes, for example, recovery rate and recovery percent of reserve etc. The method of determining Weibull peak shape development model in the initial stage of development is proposed. Three type curves and their matching methods have been presented. They are the lgV_D vs lgR_p type curves, the lg V_D vs lg(c~(0.5)t) type curves and the lgR_p vs lg (c~(0.5)t) type curves in the middle-late stage of oilfield development. The recovery rate is Weibull probability density. The recovery percent of reserve is Weibull probability distribution. |
