چکیده

Type Curve Development is an application of computer programming in well testing as a common problem in oil industry. In this work, Diffusivity Equation with specified boundary and initial conditions were first solved using Laplace transformation. A numerical method, Stehfest Algorithm, was used to find inverse Laplace transformation. VISUAL FORTRAN programming software and EXCEL software were used to generate a beneficial program for one of the major well testing designers, type curve match process. Programming aimed to develop new precise and easy to use type curve for calculation of reservoir properties from well testing data. The type curve developed in this work was used to obtain reservoir parameters for an actual data set of pressure build up test from one of Iranian reservoirs. The same parameters were obtained using PANSYS SOFTWARE. The results were then compared to check the accuracy of type curve just developed. The results exhibited a satisfactory agreement with the results of PANSYS SOFTWARE.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
