  • High strength foamed well cement compositions and methods
    Patent number: 6500252
    Abstract: High strength foamed well cement compositions and methods of cementing subterranean zones penetrated by well bores are provided. The foamed well cement compositions are basically comprised of a hydraulic cement, hydrophilic fibers, water sufficient to form a pumpable slurry, a mixture of foaming and foam stabilizing surfactants and sufficient gas to foam the slurry.
    Type: Grant

  • Method, system and device for testing two-phase compressible compositions having gas under pressure
    Patent number: 5869750
    Abstract: A method and system for testing a two-phase compressible composition, such as a foamed cementing composition, enables testing for mechanical properties while maintaining original pressurized gas volumes in the composition. A specimen of the composition can be prepared, transferred and tested without disrupting the dynamic status of the specimen. This allows for testing of the composition under conditions in which the composition will be placed in an oil or gas well. A related specimen test device is also disclosed.

  • Core sample test method and apparatus
    Patent number: 5868030
    Abstract: A core sample test apparatus applies pressure to the core sample and measures responsive longitudinal deformation with two sensors and lateral deformation with two orthogonal pairs of diametrically disposed sensors. The apparatus holds the core sample under test in a sleeve to which no or insignificant end torsional forces are applied during installation due to rotationally blocked washers used adjacent the ends of the sleeve. Concurrent acoustic testing can also be applied.
