Method, system and device for testing two-phase compressible compositions having gas under pressure

A method of testing a foamed cementing composition, comprising:

• preparing a foamed cementing composition in a vessel having a paddle, including creating relative rotation between the paddle and the vessel and flowing a gas into the vessel under a pressure greater than atmospheric pressure;
• increasing the pressure in the vessel to a test pressure simulating a pressure in an oil or gas well;
• pressurizing a hydraulic fluid chamber to the test pressure;
• pressurizing a transfer flow collection chamber to the test pressure;
• communicating the pressurized hydraulic fluid chamber with the exterior of a sleeve retained in a specimen test device and communicating the pressurized transfer flow collection chamber with the interior of the sleeve in the specimen test device;
• communicating the pressurized vessel with the interior of the sleeve in the specimen test device;
• and
• relieving the pressure in the transfer flow collection chamber to allow flow from the pressurized vessel to the pressurized transfer flow collection chamber such that a portion of the foamed cementing composition is transferred into the sleeve of the specimen test device without disrupting the pressurized state of the foamed cementing composition.

A system for preparing, transferring and testing a foamed cementing composition, comprising:

• a vessel to receive constituents for creating a foamed cementing composition under pressure;
• a source of a fluid for foaming the cementing composition;
• a pressure booster having an inlet connected to said source of a fluid and having an outlet connected to said vessel;
• a specimen test device having a sleeve disposed therein;
• a hydraulic fluid chamber;
• a transfer flow collection chamber;
• a first valve, said first valve connected to an outlet of said vessel and to an inlet of said specimen test device;
• a second valve, said second valve connected to said hydraulic fluid chamber and to said specimen test device such that said second valve controls communication of pressure from said hydraulic fluid chamber with an exterior of said sleeve;
• a third valve, said third valve connected to said transfer flow collection chamber and to said specimen test device such that said third valve controls communication of pressure from said transfer flow collection chamber with an interior of said sleeve;
• means for connecting said pressure booster with said hydraulic fluid chamber;
• and
• means for connecting said pressure booster with said transfer flow collection chamber.

A method for testing a two-phase compressible composition, comprising:

• pressurizing the two-phase compressible composition in a first vessel to a pressure greater than atmospheric pressure;
• pressurizing a second vessel to the pressure;
• transferring at least a portion of the composition from the first vessel to the second vessel while maintaining at least substantially the pressure on the transferred portion of the composition;
• and
• while maintaining at least substantially the pressure in the second vessel, testing the portion of the composition transferred to the second vessel;
• wherein pressurizing a second vessel to the pressure includes:
• pressurizing a first branch of a pressurizing system to the pressure;
• pressurizing a second branch of the pressurizing system to the pressure;
• and
• communicating the first branch with a first side of a receptacle in the second vessel and
• communicating the second branch with a second side of the receptacle.
