Injection Fall-Off Test ( IFOT)
Well testing other than to specify capability of a layer or formation to produce also obtain reservoir characteristic data.
Falloff Test Injection where do provides a disturbance of pressure balance with inject the water into the reservoir with a predetermined flow rate then shut in.
Purpose from Falloff test Injection are :
1. Obtain reservoir data : permability and transmibility
2. Evaluating of completion condition.
3. Measure of injection pressure and reservoir static pressure.
4. Observing and identifying reservoir anomalies.
For Falloff test Injection where inject the water into the well at a constant flow rate until shut in.
