Development of a Software for Some Applications of Superposition Principle in Well Testing

Abstract

This paper presents an interactive computer program that uses Visual Basic 11.0 programming language to develop user friendly and efficient software for application of superposition principle in well testing and analysis.A flow chart was created to outline the basic steps employed in the development of the software. Several user-friendly forms were designed for input and output of parameters and efficient codes were created for fast calculation of the desired output. Result showed that this software can satisfactorily compute for pressure drop, total pressure drop and sandface pressure for all cases of applications of superposition principle considered (multiple wells, variable flow rates, boundary effects and pressure change). Validation of the software showed that results had acceptable level of accuracy, this work provides a basis for development of a suite of well testing software that are problem specific, cheap, user friendly and fast.
