Jar effectiveness quantified

摘要

Almost all slickline and braided-line operations manipulate mechanical devices downhole. These operations rely heavily on the skills of the wireline operator, who until now had only had two primary information sources: a depth recorder and a surface weight indicator. Operating companies including Marathon Oil Company were keenly interested when Impact Guidance Systems developed a downhole impact sensor, called Data Stem, to aid in improving and better understanding the tools, equipment, and operations conducted on slickline and braided wire. Assistance by these oil companies allowed a better understanding of the technology and support for surface and downhole tests. The sensor has proven to be invaluable in terms of physically knowing what is happening downhole in different operating conditions rather than having only assumptions based upon surface information and "feel." The sensor is now gaining acceptance by operators and service companies.
