A method of servicing a wellbore comprising placing a composition comprising cement, water, and a heat sink material into a wellbore, and allowing the composition to set, wherein at least a portion of the heat sink material undergoes a phase transition by absorbing at least a portion of the heat released upon hydration of the cement. A method of completing a wellbore, comprising forming a wellbore in a subterranean formation comprising permafrost, gas hydrates, or both, preparing a cement composition comprising cement, water, and a heat sink material, placing the cement composition into an annulus formed between a casing and the wellbore, and allowing the composition to set, wherein at least a portion of the heat sink material undergoes a phase transition by absorbing at least a portion of the heat released upon hydration of the cement, thereby reducing an amount of heat transferred from the annular cement to the surrounding permafrost and/or gas hydrates.

The cement composition used can alternatively comprise hydraulic cement, a water reducing additive, a dispersing additive, a set accelerating additive and water. Also, the cement composition can be made environmentally benign by using water reducing and dispersing additives, set retarding additives, and compressive strength and set accelerating additives which are environmentally degradable.

Methods of cementing

A method and apparatus for foaming and then testing the foamed fluid. The apparatus comprises a cylindrical pressure vessel with upper and lower caps. A circular disk with a plurality of openings, which are preferably circular openings, is placed in the pressure vessel. The apparatus also includes a motor with a shaft extending therefrom. The shaft is attached to the pressure vessel so that when the motor is actuated, the pressure vessel can be rotated in a desired revolutions per minute. The method includes placing a mixture in the pressure vessel and then attaching the caps to the upper and lower ends of the vessel. The upper cap has a pressure gauge and has a pressure inlet and a pressure relief valve. The circular disk is placed in the vessel. The vessel is pressurized to a desired pressure with a gas motor. The motor is then actuated to rotate the vessel. As the vessel rotates, the circular disk is caused to move through the mixture, which will contain at least water, cement and a foaming agent, to disperse the gas through the fluid. The rotation of the vessel will filly foam the fluid. Tests can then be conducted on the filly foamed fluid. A fluid loss test can be conducted by opening the pressure relief valve to relieve pressure in the vessel and by opening a valve in the bottom cap to allow filtrates to pass out of the vessel. Compression tests can be conducted by curing the mixed sample inside the vessel at a desired temperature for a desired time and thereafter removing the cured sample from the pressure vessel to conduct compressive strength tests.

Apparatus and method for foaming fluids and for testing foamed fluids

The present invention provides improved early-enhanced strength cement compositions and methods. The cement compositions can be utilized in surface construction projects as well as in the construction of oil, gas and water wells. The improved cement compositions of this invention are basically comprised of a hydraulic cement, water present in an amount sufficient to form a slurry and hydrophobic silica powder.
