  • Evaluating foamed cement under pressure and temperature
    Patent number: 6829922
    Abstract: A test method for foamed cement does not transfer the test composition under pressure from one device to another and the equipment is not handled under dangerous pressure, thereby providing a safe test method. Steps include: rotating a paddle at a first speed in a pressurized foamable cement composition in a receptacle in a high pressure, high temperature chamber such that the foamable cement composition becomes a foamed cement; rotating the paddle at a second speed in the pressurized foamed cement for a selected time period; maintaining the foamed cement static after the selected time period and increasing temperature in the chamber during a foamed cement setting period; thereafter reducing temperature in the chamber and reducing pressure in the chamber; removing the foamed cement in a set condition and the paddle from the chamber; removing the set foamed cement from the paddle; and testing the removed foamed cement.
