CEMENT COMPOSITIONS FOR CONTROLLING WELLSITE FLUID AND GAS FLOW
Magnesium oxysulfate cement compositions for controlling fluid and gas flow through a wellbore may be implemented to provide a barrier to fluid and gas flow between casings or in other operations such as squeeze operations. Compositions may include an admixture of magnesium oxide, magnesium sulfate trihydrate and water. When admixed with water, the compositions rapidly transition from a flowable state to a solid state with formation of little or no gel strength before the transition and have a near-linear relationship between the time required for the transition to occur and the composition temperature at which the transition occurs enabling the user to determine the time within which the transition will occur. Accelerators and inhibitors can be added to modify the time in which the compositions make the transition from flowable state to solid state. Other agents can be added to modify the specific gravity and viscosity of the compositions.
