    摘要: A sealant composition, comprising an alkali metal silicate and a calcium containing inorganic compound, wherein the particles of the calcium containing compound have a mean particle size that is submicron, is useful for sealing cracks, fissures and voids in subterranean wells, thereby restoring zonal isolation. The mean particle size of the calcium containing compound is preferably smaller than 100 nm.

    摘要: Disclosed is a cement composition comprising polymeric particles with inorganic fillers for application in oil well cementing. The fillers improve bonding between the polymeric particles and the cement matrix leading to improved mechanical parameters of the cement system. The filled particles may also lead to improved mixability and slurries that are easier to optimise.

    摘要: A water absorbing composition includes a particle having a core of a water-swelling material. A coating substantially surrounds the core that temporarily prevents contact of water with the water-swelling material. The coating may be formed from a layer of water degradable material or a non-water-degradable, non-water absorbent encapsulating layer. A quantity of particles including delayed water-swelling particles formed at least in part from a water-swelling material and, optionally, non-water-swelling particles of the same or different size distributions can be used in treating a formation penetrated by a wellbore. A slurry of the particles is formed with a carrier fluid. The slurry of particles is introduced into the wellbore of the formation to facilitate treatment.

    摘要: An acoustic detection of a discrete acoustic signal allows to detect a leak behind a casing (23) of a borehole. An acoustic amplitude (AA) is sampled during a recording time period (24;64) at a determined position along the tube. Time intervals (26;66) are defined inside of the recording time period (24), and for each time interval (26) the measured acoustic amplitudes are processed to obtain respectively a corresponding power-frequency spectrum (261). A plurality of the power-frequency spectra are analyzed to identify the discrete acoustic signal by detecting time and frequency dependant changes of power. Preferably the processing involves a Fourier transform analysis. A power-frequency time plot is used to conveniently identify the discrete acoustic event.

    摘要: A method of consolidating a fracture in a formation comprises injecting a solution of an alkali metal silicate into the formation causing the solution to react with the surfaces of the calcium containing inorganic compound deposits, locking the fine material on these surfaces in place and preventing fines generation during production in a well.

    摘要: Disclosed are compositions and methods for providing fluid-loss control in subterranean wells. Well-completion fluids contain fine particulate additives whose glass-transition temperatures are below the anticipated bottomhole temperature. The particles soften upon injection into the well, whereupon they soften and become deformable. The particles then migrate to the borehole wall and form a seal that reduces further fluid flow from the borehole into the formation. The additive may be supplied as a powder or in the form of a liquid suspension.
