Abstract:

Reading a book is great. Listening to a story is even better. A similar situation happens in a well. Active wells produce a series of sounds downhole. Understanding the source of these sounds helps tremendously in the optimization of the well's performance. 

Production gaps are due to many causes, one of which is crossflow. The crossflow can be between pipes, past a sealing element, in the cement-formation interface, etc. Since the leak flow is a dynamic phenomena, it seems appropriate to obtain dynamic data to understand it. Fluids moving behind pipe create friction, turbulence and … sound.  The well talks to us, and we should listen!

Optimization of production rates with minimum intervention expenditures requires a reduction in the uncertainty associated with the diagnostics of the root causes of the production gap. If as mentioned above, the cause is a leak, the effectiveness of a waterflood, for example, would rely heavily on the accurate diagnosis of such a leak.

A very comprehensive example of an injector well on a onshore mature oil field is shown to illustrate how listening to the well, plus the integration of multiple dynamic and static downhole logs dramatically reduced the uncertainty of the location of the crossflow. Only a fraction of the water injected was helping to produce the oil out, while the rest was accumulating (wasted) in a shallower zone. The economic impact of accurate leak detection cannot be emphasized enough. Fortunately we listened to the well!
