Abstract
Fo recasting produc tion is one o f the m ajor approaches wh ile estim ating the effec tivenessw hen o ilfield deve lopm ent is to be ad justed. Th is paper comb ines the advantages of both the decline curve and the grow th cu rve In orde r to pred ict the production quick ly and accurately. The A rps hyperbolic decline cu rve is used to predict the production declin ing. The W e ibull g row th curve is used to predict the production after the o ilfie ld developm ent is adjusted. Using th is m ethod, the effect of tertiary process is estim ated and the resu lts are compared to those from o ther m ethods. It ind icates that the m ethod is easy and sim ple and has little m an - induced effect.
