Case Study 1: The Effect of Nearby Wells on Well Test Results (A Horizontal Oil Well)
Inter-Well Communication in a Real Field Experience: As shown in the following plot, the bottomhole pressure data from a ~10-day buildup test in one of the horizontal oil wells in the Middle East does not exhibit a normal trend. Further investigations revealed that the pressure behavior was influenced by nearby producing wells. About three hours […]
Cyclic Production (Causes and Solutions)
Some wells in the Middle East have “Cyclic Production” behavior. For example, they produce for 10 days and then need to be shut in for 7 days so the reservoir can recharge, after which the well can be opened again. What causes this behavior? And what are the solutions for maintaining production from such wells? […]
