Abstract: A well tool pressure compensating system for connecting well tubing sections or well tools and providing pressure and/or thermal compensation along the entire length of the tool in a wellbore. The system can include first and second connectors each including fluid components and power and/or signal components. A tubing allows fluid to travel between the first and second connectors and along the tool. A hose traveling along and within the tool is in fluid communication with a wellbore fluid, thereby providing pressure and thermal compensation along the tool. A flexible tubing extends between the first and second connectors within the tool. The flexible tubing is in fluid communication with an area around the power and/or signal components of the first and second connectors, thereby providing pressure and/or thermal compensation around the power and/or signal components.

Abstract: A method and apparatus for subterranean thermal conditioning. The first step involves providing a tubular magnetic induction apparatus. The second step involves positioning the magnetic induction apparatus into a subterranean environment. The third step involves supplying voltage waves to the magnetic induction apparatus thereby inducing a magnetic field in and adjacent to the magnetic induction apparatus to thermally condition the subterranean environment. This method and apparatus has application in the petroleum and mining industries.
