LOW COST METHODOLOGIES TO ANALYZE AND CORRECT ABNORMAL PRODUCTION DECLINE IN STRIPPER GAS WELLS
The goal of this research program is to develop and deliver a procedure guide of low cost methodologies to analyze and correct problems with stripper wells experiencing abnormal production declines. A study group of wells will provide data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the historic frequency of the causes of the production problems. Once the most frequently occurring causes of the production problems are determined, data collection forms and decision trees will be designed to cost-effectively diagnose these problems and suggest corrective action. Finally, economic techniques to solve the most frequently occurring problems will be researched and implemented. These systematic methodologies and techniques will increase the efficiency of problem assessment and implementation of solutions for stripper gas wells. This seventh quarterly technical progress report further describes the data reduction and methodology to develop diagnostic tools to evaluate the cause of declines in problem wells, specifically addressing the methodology to analyze the group of wells where recent problems have occurred utilizing the data gathering forms. This report also describes the methodology to select the two wells with the greatest potential for increase and also having the most frequently occurring problem. Finally, this report describes the preliminary results of the remediation applied to the two wells selected. Two wells selected and analyzed from a twenty-four well study group indicated that their current abnormal production decline was attributable to fluid build-up in the wellbore. Subsequent remediation work of putting both wells on pump to reduce fluid build-up in the well bore decreased the flowing bottom hole pressure and increased gas production dramatically.
