Interference testing using horizontal wells in anisotropic reservoir

This thesis presents a model for interference testing utilizing two horizontal wells of unequal lengths. Interference testing between two finite conductivity horizontal wells has not been fully addressed in the literature. The purpose of this work is to present analytical pressure-transient solution for interference testing utilizing two finite-conductivity horizontal wells having unequal lengths.;This work extends the previous interference testing model between two equal-length horizontal wells to case in which the two horizontal interfering wells are of unequal length. A sensitivity study is performed to show the effect of well length on: (1) Flux distribution in both wells. (2) Pressure response in both wells. (3) Appearance of flow regimes in both wells. The new model has been validated using two previous interference testing models.
