A method and apparatus is applicable to in situ heating of oil shale or tar sand. The heating is by radio frequency that is applied down hole by a central conductor that extends beyond a coaxial shielding conductor to form the antenna or applicator. Encroachment by the heated formation is overcome b ...

William N Gilmer, Vernon M Barnes Jr: Method and apparatus for static type fluid mixing. Texaco, Thomas H Whaley, Carl G Ries, Henry C Dearborn, August 23, 1977: US04043539 (49 worldwide citation)

A static-type fluid-mixing method. It deals with mixing different fluids in a stream which are separated longitudinally. A portion of the stream is diverted laterally and the remainder is reversed after continuing in the original direction for a given distance. Both parts are then mixed by joining o ...

Joseph I Hart: Cleanout procedure for well with low bottom hole pressure. Texaco Trinidad, Thomas H Whaley, Carl G Ries, Henry C Dearborn, November 29, 1977: US04060130 (42 worldwide citation)

A cleanout procedure for use in a well with low bottom hole pressure that has become filled with sand.
