摘要： A sealant is provided which is a curable resin external emulsion having a fluid internal phase comprising a curable material which expands during, after or before it cures. The resin external phase is, for example, an epoxy resin which may shrink as it cures. The internal phase is captured within micelles to provide discrete internal phase portions supported in an out resin matrix.

摘要： A method of sealing a well includes selecting a preexisting fluid pathway between a production platform and a desired sealing location in the well to be sealed, determining, for the well to be sealed, a desired quantity of sealant having known flow qualities, to be delivered in fluid form to the well in the sealing region of the well, determining, based on the flow qualities of the sealant in fluid form and the flow qualities of the preexisting fluid pathway, the time needed to deliver the desired quantity of the sealant in fluid form to the sealing location in the well, determining, based on the time needed to deliver the desired quantity of the sealant in fluid form to the sealing location in the well, whether the sealant will maintain the fluid form, if necessary, change one or more qualities of the sealant so that the desired quantity of the sealant will reach the sealing location in the well while in the fluid form, and transport the quantity of sealant, in fluid form, through the preexisting fluid pathway between a production platform and the desired sealing location in the well to be sealed.

摘要： A method for sealing a well (3) includes: placing an obstruction in a bore of an inner tubular string disposed in a wellbore; forming an opening through a wall of the inner tubular string above the obstruction; mixing a resin and a hardener to form a sealant; and squeezing the sealant into the bore, through the opening, and into an annulus formed between the inner tubular string and an outer tubular string, thereby repairing a cement sheath present in the annulus.

摘要： Provided herein are methods of formulating a sealant to span an opening and form a seal with surfaces across the opening including selecting a fluid material capable of contacting and adhering to the surface of the opening and which reacts to form a solid material as a result of a thermal reaction, and selecting and intermixing one or more solids with the fluid material to form a composite, wherein the solids migrate within a column of the composite sealant before the composite sealant cures from a fluid to a solid and bonds to the surfaces of the opening, and the change in volume of the lower portion of the lower portion composite sealant into which the solids have migrated, as the temperature thereof changes during curing, is insufficient to cause it to pull away from the surfaces of the opening or fail internally.
