This is important when the test objective is to see the well's production profile. It is also important for determining the effects of a past stimulation that has not performed as expected. If we run a TRAC-III immediately after the well has been worked over, it will only tell us what the well does at that particular point in time. It does not matter if this increase of water production was brought on by a stimulation, direct channel from an offset injector, or natural causes. Get busy, prepare your well for a TRAC-III and call Cardinal.
Time is critical.
Don't wait for stabilization. There is a strong possibility this new water is from a higher pressure source than anything you've been producing. In these situations we regularly see crossflow into the proven oil zones. We need to find the water source so that you can take remedial action. Remember, you will have to recover all those barrels of water that cross flowed in before you will get your production back.
