Thermal injection well falloff testing

Knowledge of the swept volume permits calculation of important economic parameters including the fuel concentration in a combustion test and heat loss in a steamflood. A study was conducted to find field case histories of swept volume determination from pressure transient tests at an injection well. Several case histories are presented from both in-situ combustion and steamflood projects. An investigation for each case history shows the information that may be obtained from pressure transient tests. Pressure transient testing of the injection well may prove useful in evaluating and controlling the performance of thermal recovery projects. 16 refs.
