摘要： The invention provides compositions and methods for sealing subterranean spaces such as natural or induced fractures, vugs or annular spaces. The composition is composed of a base fluid consisting of a soluble alkali silicate, a gas generating additive, solids and a setting agent. The gas generating additive may be coated or uncoated. The gas generating additive may also be in the form of a slurry. In the case of coated additives, the coating may act as a retarder or an accelerator to the expansion and setting agent of the soluble alkali silica. Similarly, the choice of carrier fluid in a slurry may retard or accelerate the expansion and setting of the alkali silicate-based plug.

摘要： Methods for cementing a subterranean well and maintaining zonal isolation involve preparing a cement slurry that contains water, an inorganic cement and an expanding agent. The slurry is placed in the annular region between casing and the formation or between two casing strings. After the cement sets, the expanding agent reacts and causes the set cement to be in a state of compression within the annular region. The casing dimensions may fluctuate in response to a temperature change, a pressure change, a mechanical disturbance resulting from a well intervention, or mud contamination or a combination thereof. The expanding agent may further react and maintain a state of compression within the annular region. The state of compression in the annular region may be monitored by acoustic impedance measurements.

摘要： Magnesium oxysulfate cement compositions and methods for controlling and preventing fluid and gas flow through a wellbore are described. The compositions and methods may be implemented to provide a barrier to fluid and gas flow between casings or in other operations such as squeeze operations. Magnesium oxysulfate cement 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 further 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. Additives, such as 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.
