A computationally efficient, transient-pressure solution for inclined wells

This work provides an efficient algorithm to compute transient pressure res ponses of inclined wells. The solution is derived in the Laplace domain and cast into computationally efficient forms for all inclination angles. The algorithm allows the computation of pressures and derivatives at the wellbo re as well as at observation points. Short- and long-time approximations fo r the evaluation of pressure responses are also provided. The long-time app roximation is used to derive a general pseudoskin expression that is applic able for all inclination angles. Example computations are presented in the forms of tables and figures to display the efficacy, accuracy, and the prac tical use of the algorithm.
