Eike Rietsch: Method for determining the extent of subsurface reaction involving acoustic signals. Deutsche Texaco Aktiengesellschaft, Carl G Ries, Robert A Kulason, Ronald G Gillespie, June 28, 1983: US04390973 (171 worldwide citation)

A method determines the extent of subsurface reactions in which random acoustic signals are radiated from a whole area covered by the reaction or from a boundary region, hereafter termed reaction front, between largely undisturbed rocks and those already covered by the reaction. The signals are reco ...

Russell D Shupe, Jim Maddox Jr: Surfactant oil recovery process usable in high temperature, high salinity formations. Texaco, Carl G Ries, Thomas H Whaley, Jack H Park, March 7, 1978: US04077471 (168 worldwide citation)

Many petroleum formations contain water having high salinity and/or high concentrations of divalent ions such as calcium or magnesium dissolved therein, and are additionally at temperature from about 70.degree. F. to about 300.degree. F. Most surfactants suitable for use in oil recovery operations a ...
