Paper: Selecting Wells for Stimulation

The stimulation of wells to increase the productivity has had wide acceptance in the industry in the last few years. The results have generally been beneficial, but, as in most processes, the method is not a cure-all, since in many instances the remedial operation has failed to produce the desired results. It is the responsibility of field managers and engineers, at any time, to avoid spending money on projects which will not be profitable. With limited funds available in depressed economic times, it is most important that such funds be spent on those projects with best prospects of maximum return. To aid the engineer and manager in selecting such projects, bottom-hole pressure buildup data, in many cases, have been of value. The analysis of these data is discussed using three approaches with examples of each method.
