Downhole video services enhance conformance technology
Conformance Technology can be defined as ``the application of processes to reservoirs and boreholes to enhance recovery efficiencies.`` The purpose of these processes is not to increase production but to reduce and dispose of unwanted bi-products; i.e., water, gas, sand, etc., and the associated costs generated by their disposal. Conformance technology has been practiced in the oilfield for many years, but it is gaining in importance because of environmental and economic constraints that limit operator options for the disposal of unwanted production. The successful practice of conformance technology is dependent upon a thorough understanding of the downhole conditions in each well, as misinterpretation of downhole data can result in the application of treatment that will not successfully address the problem. This paper describes applications for downhole video services that facilitate: Planning of conformance technology treatments; provision of in-process treatment monitoring; and confirmation of post-treatment success. Three case histories showing different applications of video services in conjunction with the planning and confirmation of treatments are presented. The first case determined fluid entry under flowing conditions and better defined which zones required treatment. The second case showed that the original well diagnosis was incorrect and that the planned treatments would not be effective, while the third case showed how a downhole video survey was used as a pretreatment analytical tool and later used to confirm a successful treatment.
