Abstract

As the economic importance of natural gas continues to grow, gas well surveillance equally generates more interest to the petroleum industry. The flowing bottom-hole pressures must be known in order to predict the productivity or absolute open flow potential of gas wells. These parameters are measured using down-hole gauges method of gas well test. In gas wells, down-hole parameters could be estimated using mathematical expressions instead of measured directly using gas well test procedure so that it will saving lots of dollars. The conventional method of gas parameter measurement include the iterative method, the Sukkar and Cornell method, Cullender and Smith method. Others are Crawford and Fancher and the Poettman method. All these methods involve very long and cumbersome iterative procedures. This makes the job of the field men very tedious, especially when the unit system changes. Similarly, data integrity is not guaranteed because data is far from actual. This research work presents a mathematical model for the predicting flowing bottom-hole pressure in gas wells, using the Average temperature and deviation method and the Cullender and Smith method. It utilizes a userfriendly window based Visual Basic for Application in Excels with adjustable unit system.
