Abstract
Systems and methods related to preparing foamed cement for laboratory analysis are provided. A prepared cement slurry is placed in a cement reservoir cell configured to pressurize the cement slurry contained within the cement reservoir cell to a capture pressure. After pressurization, the cement slurry and a compressed gas are introduced into a foam generator. Foamed cement generated in the foam generator is introduced from the tee into a foam capture cell where it can cure prior to analysis.
Claims18
An apparatus for preparing foamed cement for laboratory analysis comprising:
- a first source of pressurized gas;
- a cement reservoir cell configured to pressurize a cement slurry contained within the cement reservoir cell to a capture pressure selected to correspond to the conditions at a well site;
- a foam capture cell;
- a foam generator in the form of a tee and having a first leg in fluid flow communication with said source of pressurized gas, a second leg in fluid flow communication with said cement reservoir cell, and a third leg in fluid flow communication with said foam capture cell, wherein said foam capture cell is configured to receive a pressurized foamed cement from said foam generator and has a first cylinder;
- and wherein gas from said first source of pressurized gas is introduced into said foam generator through a choke;
- and
- a second source of pressurized gas for providing an initial pressure to said first cylinder.
