Pressure behavior of horizontal wells in naturally fractured reservoir

SUMMARY PRESSURE BEHAVIOR OF HORIZONTAL WELLS IN NATURALLY FRACTURED RESERVOIR Theoretical "studies and field results show that, horizontal wells have a great performance in thin reservoir and fractured reservoirs, and in the case of water coning and high vertical permeability. Several works on the pressure behavior and productivity of horizontal wells have been published [l]-[6]. The pressure equation for horizontal wells in homogenous reservoirs which is used in this study to derive an equation for naturally fractured reservoirs was obtained by Clonts and Ramey,[l] and Özkan et al, [2]..PD" 1+XS) +erf(.İ^)]exp( i|> [1+2 £exp(-ii2n2L^) a»i coamtZj, cosnrcz"D ] -^*- vT Her "d \xDi y^, z0, zwD, ld, cD) - kh {Pi-P{xty,zrzu,L,t) 141.2$B»i _ 0.001055 kt 4>CcJiL2 Yd' ZWD 2x L L _Z h Jk h L*" L k VI
