  • Patent number: 6971260
    Abstract: A compression cell for rock or soil core samples applies and restores lithostatic or overburden pressure to core samples extracted from wells drilled deep into the earth. A method of applying lithostatic pressure to a core sample is disclosed along with the apparatus which effects the application. The cell construction that maintains the litho static pressure and the process of utilizing the cell and sample under essentially deep earth ambient conditions are set forth.

  • Patent number: 4936340
    Abstract: A pressure control assembly is disclosed. The assembly includes a pressure transducer for detecting upstream pressure. A diaphragm is used to regulate flow through the assembly, and is forced into a closed position by pressure from a fluid column. The pressure on the fluid column is controlled by a piston driven by a step motor. The step motor is activated in response to signals from the pressure transducer.
