摘要： A method of treating a subterranean formation via well bore may include introducing a plurality of particles into the subterranean formation via the well bore, each particle having a substrate and a layer of cement on the substrate. The cement may be in a state of suspended hydration and the method may include introducing moisture to the subterranean formation via the well bore. The method may also include allowing the particles and the moisture to contact one another. Contact between the particles and the moisture may cause the cement to move from a state of suspended hydration to a state of secondary hydration.

摘要： A method and apparatus are provided for intentionally inducing "formation plugging" in a partially damaged section, water layer, or an otherwise undesirable target zone in the wall of a wellbore. The rigless apparatus is deployed to the target zone by coiled tubing and includes a pair of adjacent inflatable packers or a multi-section inflatable thermoplastic balloon component which is in valved fluid communication with an inflating container filled with formation plugging fluid. The inflating container is in valved fluid communication with a reactant-filled chemical container, the reactant being activated by contact with reactant fluid pumped through the coiled tubing via a circulation valve. The hot pressurized exothermic reaction products pass into the inflation container and displace the formation plugging fluid into the balloon sections and through weakened portions of a central balloon to penetrate the walls of the target zone. The expanded central balloon is melted by the heat of the chemical reaction and a portion adheres to the formation wall thereby sealing the undesirable target zone; thereafter, the remaining balloon sections are deflated or ruptured to permit the apparatus to be withdrawn through the production tubing.

摘要： In a method of sealing a fracture (1) in a formation (2) surrounding a wellbore provided with a non-cemented perforated liner (4), a placement tool (6) is introduced into the liner and so positioned that a sealing fluid outlet (7) of the placement tool is located at the fracture (1). A placement section (8) including the sealing fluid outlet is pressed against the liner. A placement fluid is caused to flow into the fracture and controlled to obtain a desired fluid flow in an annular space (5) between the liner and the formation that is directed in downstream direction at a position upstream the fracture and that is directed in upstream direction at a position downstream the fracture. When said desired flow is obtained, sealing fluid is ejected from the sealing fluid outlet. A sealing system is furthermore disclosed.

摘要： A barrier onto the surface of a subterranean formation may be formed by pumping into a wellbore within a well hydrophobically modified polysaccharides. A pressure differential is created between the reservoir pressure and formation pressure within the well. The micellular hydrophobically modified polysaccharides self-align onto the face of the formation to form the barrier. Flow of fluids into the subterranean formation is thereby prohibited.
