Patent ID: 8783091

Claim:
A system for testing cement, the system comprising: at least one cement testing apparatus, each cement testing apparatus comprising: a pressure vessel defining: a working volume inside the pressure vessel, the pressure vessel defining a first channel providing liquid communication through the pressure vessel to the working volume of the pressure vessel and a second channel providing liquid communication through the pressure vessel to the working volume of the pressure vessel; and a substantially tubular sample container comprising walls extending from a first end with a first end member having an opening to a second end with a second end member having an opening, the end members configured to grip ends of a cement sample in the sample container, the sample container disposed in the working volume of the pressure vessel with the sample container substantially sealed to prevent liquid communication between a sample volume, defined by the first and second end members and a tubular member of the sample container, and portions of the working volume of the pressure vessel outside the sample container, the tubular member comprising a specified material that is more flexible than a material of the first and second end members, the tubular member comprising walls that are substantially sealed to the first end member and the second end member; wherein the sample container is positioned such that the first channel provides liquid communication through the pressure vessel to the sample volume of the sample container; and the second channel provides liquid communication through the pressure vessel to the portions of the working volume of the pressure vessel outside the sample container.
