Embodiment 1

[0046] The effect of quaternary ammonium materials on the viscosity of Sorel cement was studied. Specifically, Sorel magnesia cement is THERMATEK TM Rigid setting fluid, which is MgO and MgCl purchased from Halliburton Energy Services 2 ·6H 2 O mixture. THERMATEK TM A hard setting fluid slurry was prepared as follows: 450 g of C-TEK was dissolved in 300 g of water in a Waring mixer; 450 g of THERMATEK was added to the C-TEK solution TM LT to prepare the slurry. Add AMMONXY SDBC stock solution to THERMATEK TM A specified amount of quaternary ammonium material was added to the hard solidified fluid slurry, and the AMMONXY SDBC stock solution was quaternary amidopropyl benzyl dimethyl ammonium chloride purchased from Stepan. The concentration of the stock solution is 60%. The rheological properties of the fluids were measured with a FANN 35 viscometer at 3, 6, 100, 200, 300 and 600 RPM at room temperature. Viscosity, plastic viscosity (centipoise) and yield point (lbs / 10...

[0052] The addition of quaternary ammonium materials to THERMATEK TM Influence of Hard Setting Fluids and Compatibility of Oil-based Muds. THERMATEK TM A hard-setting fluid slurry was prepared as follows: In a Waring mixer, 450 g of C-TEK was dissolved in 300 g of water; to the C-TEK solution was added 450 g of THERMATEK TM LT to prepare the slurry. to THERMATEK TM To the hard setting fluid slurry was added 5 ml of an 83% solution of ARQUAD 83E, a quaternary amine available from Stepan. to THERMATEK TM To the mixture of hard setting fluid and quaternary ammonium material was added the indicated amount of PETROFREE LV, a synthetic slurry available from Halliburton Energy Services. At room temperature, the rheological properties of the fluid were measured with a FANN 35 viscometer at 3, 6, 100, 200, 300 and 600 RPM, and allowed to solidify at room temperature for 24 hours to determine the compressive strength of the coagulated composition. Viscosity, plastic viscosity (ce...

Abstract

A wellbore servicing composition is described comprising a metal oxide, a soluble salt and a viscosifier wherein the viscosifier comprises a quaternary amide, a quaternary amide ester, or combinationsthereof. A method of servicing a wellbore in contact with a subterranean formation is also described, the method comprising viscosifying a cement composition comprising a metal oxide and a soluble salt, placing the viscosified cement composition in the wellbore, and allowing the composition to set.

Description

technical field [0001] The present invention relates generally to wellbore servicing fluids, and more particularly to viscosified Sorel cement and methods of using the same. Background technique [0002] Natural resources such as gas, oil, and water located in subterranean formations or subterranean regions are typically obtained by drilling a wellbore into the subterranean formation while circulating a drilling fluid in the wellbore. After the circulation of the drilling fluid is terminated, a string of tubing, such as casing, is run in the wellbore. Drilling fluid is then usually circulated down through the inside of the pipe and up through the annular casing, which is located between the outside of the pipe and the well wall. Thereafter, a first cementing is usually performed whereby the cement slurry is placed in the annular casing and allowed to set into a hard mass (ie, a sheath) which connects said string of tubing to the borehole wall and seals the annular casing. ...
