Integrating Wellbore Modeling and Production History to Understand Well Behavior

Abstract

A study of well behavior in the Awibengkok reservoir, Indonesia, demonstrated how production history, pressure and temperature surveys could be combined with wellbore modeling to provide insight into well behavior. Wellbore models were constructed for every producing well and a wellbore simulator was run in batch mode to automatically produce calculated total mass and enthalpy every three months for the entire production history of each well. The final result was a set of wellbore hydraulic models that match production history for each well. The calibrated models were then used for short-term deliverability predictions as an alternative to well decline analysis.
