There has been some excellent benchmarking done in the North Sea and Europe. Several years ago, the Well Intervention Excellence Network showed what was possible. In an SPE paper, a group of 22 operators reviewed the success levels that could be achieved, and the results were enlightening. Their review of historic data found that on average about a 10% contribution to production could be achieved by performing interventions. On offshore platforms, the rate was as high as 16%. Onshore wells saw a 9% increase. If we consider the cost per barrel as demonstrated and the potential production increases, then the case becomes incredibly compelling. I would argue that these figures can be increased with the right focus and new technologies.
