DRC and the SPIDR well testing system have been a great tool in the evaluation process of the wells I look over. They have been very dependable and accessible for the many years that I have been using them. I have been using ...

Injection Fall-Off Tests
As with a producing well, injection wells may also build "skin" over their operating life.
This skin may result from the accumulation of foreign matter screened or filtered from the injected fluid. The magnitude of the skin and the permeability of the reservoir in the area around the wellbore is determined from the injection fall-off test. This test is similar to the build-up test in that the change in wellhead pressure is monitored after flow is interrupted. The SPIDR is connected to the well as shown on the left.

If it can be determined early in the life of an injection well that there is an appreciable "skin effect" , remedial measures may be started before a full-scale pattern flood begins. Similarly, if tests show that a gradual buildup of skin is occuring with time, it is possible to take measures to free the water of plugging material. Finally, determination of the permeability of the sand around the injection well will allow estimation of the future relation between injection pressure ... read more
