  • Patent number: 6577391
    Abstract: An apparatus embodying the invention includes a probe head with an interrogation surface that is intended to be positioned adjacent or pushed into contact with a target material or tissue. The probe head is constructed to have a plurality of interrogation devices arranged across the face of the interrogation surface. The probe head is also constructed so that the interrogation device can conform to a non-uniform or non-planar surface of the target tissue. In some embodiments, the interrogation surface may have a particular shape that conforms to the shape of a target material. In other embodiments, one or more portions of the interrogation surface could be movable with respect to the remaining portions so that the interrogation surface could be movable with respect to remaining portions so that the interrogation surface can the thereby conform to a non-uniform surface. In still other embodiments, a plurality of separately moveable interrogation devices can be arranged across the interrogation surface.

  • Publication number: 20030070804
    Abstract: A process for in situ gasification of mineral oil in a subterranean formation comprises running a tool having a controllable thermal device therein from a surface production facility down to the subterranean formation, bringing said tool into operational proximity with the mineral oil in said subterranean formation, and activating the tool to operate the thermal device within a predetermined temperature range to generate gases or oily vapours from said mineral oil, which permits either an enhanced oil recovery (EOR) method with reduced water contamination, or a gas production process (GPP) which is useful in reducing environmental risks normally associated with transport of crude oil.

  • Patent number: 4968788
    Abstract: Protective groups are provided which are suitable for masking phosphates and phosphonates. The protected compositions can be introduced in a biological system and then demasked under certain biological conditions. This method permits phosphates and phosphonates which would themselves degrade in the biological system and therefore be ineffective to be introduced in a protected form and late released under the proper conditions.
