Temperature transient analysis models and workflows for vertical dry gas wells

The developed TTA workflow has therefore been validated for many practical TTA applications, as shown by its successful application and validation against conventional pressure transient analysis (PTA) for both synthetic and real-well data sets. TTA's unique ability to estimate the radius and permeability of a low permeability (formation damage) zone around the wellbore was also validated. This important parameter is not available from PTA. This work represents a further important step towards the development of a comprehensive PTA/TTA data analysis framework for multi-phase production wells.
