Investigation of the Market Potential for a New Cased Hole Formation Tester.Final Report, August-September 1994

摘要

Wireline formation testing is an integral part of open hole well evaluation, withtests run on approximately 25% of all new wells. Formation test wireline tools are used to measure formation pressure and obtain fluid samples from the potential producing formations, in order to determine if there are hydrocarbons in the reservoir, and if the volumes are commercial. There are instances, however, when this type of information would be valuable in an already cased well. By far the most prevalent is the situation of an old producing well with other potential zones. Old wells often lack evaluation logs and formation tests. This study aims to determine potential customer interest and market for a new tool with a capability to take multiple pressure and sample tests, and to seal the holes it put into the casing for these tests.
