The main objective of this study is to develop the optimal.semi-anal.tical.modeling for the infiniteconductivity horizontal.well performance under rectangular bounded reservoir based on a new instantaneous source function. The available semi-anal.tical.infinite-conductivity models（ICMs） for horizontal.well under rectangular bounded reservoir in literature were developed by applying superposition of pressures in space（SPS）. A new instantaneous source function（i.e., instantaneous uniform-flux segmentary source function under bounded reservoir） is derived to be used instead of SPS to develop the optimal.semi-anal.tical.*** new semi-anal.tical.ICM is verified with ICM of Schlumberger [1] and with previous semi-anal.tical.ICMs in terms of bottom hole pressure（BHP） profile and inflow rate distribution al.ng the wellbore. The model is al.o val.dated with real.horizontal.wells in terms of inflow rate distribution al.ng the wellbore. The results show that the developed model gives the optimal.semi-anal.tical.modeling for the infinite-conductivity horizontal.well performance under rectangular bounded reservoir. Besides that, high computational.fficiency and high-resolution of wellbore discretization have been achieved（i.e., wellbore segment number could be tens of hundreds depending on solution requirement）. The results al.o show that at pseudosteady state（PSS） flow regime, inflow rate distribution al.ng the wellbore by previous semi-anal.tical.ICMs is stabilized U-shaped as performance of inflow rate distribution at late radial.flow regime. Therefore, the previous semi-anal.tical.ICMs are incorrectly modeling inflow rate distribution at PSS flow regime due to the negative influence of applying SPS. The optimal.semi-anal.tical.ICM is in a general.form and real.time domain,and can be applicable for 3D horizontal.well and 2D vertical.fracture well under infinite and rectangular bounded reservoirs, of uniform-flux and infinite-conductivity wellbore conditions at any time of
