  • TCH--tri-axial core holder
    Patent number: 4599891
    Abstract: A core holder is described which shows a rock core in a resilient sleeve within a hollow housing. A longitudinal axial force is applied on the core independently of pressure applied radially on the core. Fluid pressure or flow is measured at the periphery of the core during injection of fluids therethrough while various pressures are independently applied at infinitely variable degrees of radial and longitudinal axial forces.

  • Connector for core holder
    Patent number: 4572009
    Abstract: This concerns a core holder for a rock core in a resilient sleeve within a hollow housing. Longitudinal and radial forces are applied to the core. Fluid samples can be obtained at selected points along the length around the diameter of the core during injection of fluids therethrough. It concerns a special stem and seal for providing fluid or gas communication from within the resilient sleeve and the exterior of the housing.
