摘要： Automated objective crosslink time and crosslink temperature determinations are provided in a method of testing for chemical crosslinking of a fluid. A fluid having a crosslinking agent is placed in a vessel and a paddle is rotated through the fluid in the vessel at substantially a constant rotational speed. A paddle torque parameter is sensed at sequential times and digital signals are encoded to define digital torque data representing values of the sensed torque parameter. In response to stored digital torque data and digital time data, a baseline torque parameter value and a change in the digital torque data representing increasing torque of the paddle are determined. In response to the baseline torque parameter value and the change in the digital torque data, a crosslink time for the fluid is determined. A crosslink temperature can also be determined. This is determined in response to the crosslink time and stored digital temperature data that has been obtained at sequential times.

摘要： A method and system for testing a two-phase compressible composition, such as a foamed cementing composition, enables testing for mechanical properties while maintaining original pressurized gas volumes in the composition. A specimen of the composition can be prepared, transferred and tested without disrupting the dynamic status of the specimen. This allows for testing of the composition under conditions in which the composition will be placed in an oil or gas well. A related specimen test device is also disclosed. The method includes 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 testing the portion of the composition transferred to the second vessel, which testing is performed while maintaining at least substantially the pressure in the second vessel.
