In these cases, the success of the conformance treatment has been totally dependent upon an accurate description of the reservoir. Obviously, without a proper determination of the reservoir conditions, the underlying reasons for the water and/or gas problems cannot be assessed, and the most appropriate treatment cannot be applied. It has now been shown that a conformance treatment can be even more effective if it is applied early in the life of the reservoir. In other words, a preventive or a proactive conformance treatment may be more successful and less costly to apply than a reactive treatment if analysis determines that the reservoir conditions are such that water and gas production are likely to occur as the field matures.Thus, since accurate reservoir description is the key to whether a treatment will be effective, regardless of whether applied early or late in the life of the well, it is obvious that the proper diagnostic and analytical tools are critical to the success of any conformance application. This fact will be proven in this paper through use of a database that contains over 900 actual conformance treatments that show that a success ratio exceeding 90% is obtained when the proper diagnostic tools are used.To apply the concept of preventive conformance, the availability of a diagnostic tool is extremely important. This tool should have the capability to determine the type and location of reservoir fluids and whether the encountered water is mobile. A powerful tool for providing this information is the MRI (Magnetic Resonance Imaging) Logging tool.This paper shows how coupling reservoir description in general and conformance in particular to MRI technology through the application of MRI logs can benefit the process. It also illustrates the technical and economical value of this technological integration through the use of simulated examples. The simulated examples were created using a commercially available 3-D, 3-phase simulator.IntroductionConformance is the management of unwanted water and gas.1,2 A conformance treatment is usually applied late in the life of the reservoir after a well begins to produce a large quantity of water and/or gas. At that point, water saturation around the wellbore is very high. A conformance treatment may significantly enhance productivity by cutting further water production, however, it is obvious that reservoir conditions would not be totally reversed, and some permanent damage can already have taken place. In this paper, we are suggesting a new approach to conformance treatment, which we will reference as "preventive Conformance." Essentially, we are suggesting that it may be more effective and cheaper to be proactive and apply a conformance treatment early in the life of the reservoir as a "preventive treatment."Success of a preventive treatment depends on the accurate determination of types and locations of reservoir fluids. Determining where we might encounter mobile water is essential to the success of this new process. We can reach this goal only through early integration of multiple technologies. However, this technology integration must start long before a treatment is even considered. One could roughly divide the stages involved in a traditional conformance treatment into the following four categories:Pre-diagnostic evaluation, which consists of candidate selection and the gathering of a complete data set including production history, economic analysis, logs, production tests, and a decline history.Diagnostic evaluation, which includes the gathering of data from reservoir monitor logs, water flow logs, production logs, cement evaluation logs, pipe inspection logs, and video.Analytical evaluation, which can include multi-rate injection with profile analysis, pump-in testing, placement evaluation, and laboratory analysis/evaluation.
