The present disclosure may relate to a method of remediating a wellbore. The method may comprise pumping a resin treatment fluid from a surface location to an annular space bounded by an outer diameter of a production tubular, wherein the resin treatment fluid comprises a liquid hardenable resin, a hardening agent, and a particulate bridging agent. The resin treatment fluid may gravity settle in the annular space to contact production equipment in the annular space such that at least a portion of the particulate bridging agent bridges across one or more damaged sections of the production equipment, wherein at least a portion of the liquid hardenable resin sets to form a hardened mass to seal the one or more damaged sections.

Various embodiments disclosed relate to compositions including a curable resin and organophilically-modified clay for subterranean oil well applications and methods of using the same. Various embodiments provide a method of treating a subterranean formation including placing in a subterranean formation a curable composition that includes at least one of a curable organic resin and a thermosetting polymer. The curable composition also includes an organophilically-modified clay.

An organic-inorganic composite including: a plurality of anisotropic ceramic particles having different aspect ratios; a resin that is combined with the ceramic particles; and a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin. At least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.

Methods for treating and restoring zonal isolation in a subterranean well involve the use of a well treatment tool that may drill one or more holes in casing and inject a treatment fluid that may seal cracks or fissures in the cement sheath behind the casing. Microannuli may also be sealed. The treatment fluids may be solids free or in the form of suspensions containing solids having a particle size between 1 nm and 100 nm.

The present disclosure relates to a cement additive composition including a polycarboxylic acid-based copolymer. When the cement additive composition of the present disclosure is used for cement formulation, it may improve fluidity of the composition even in a high water reducing ratio range of the particle and effectively prevent slump loss of the cement formulation, while improving initial dispersibility due to excellent water reducing performance.

The present invention relates to a method for producing a recycled insulating material from insulating wool, said method comprising the steps of: comminuting insulating wool to give a first intermediate comprising fibre balls; adding binder to the first intermediate to give a second intermediate; hot-pressing the second intermediate into the desired shape, to give a third intermediate; and curing the third intermediate to give the recycled insulating material. The present invention further relates to a method for recycling insulating wool, an apparatus for processing insulating wool, and a fibre-reinforced foam. The invention additionally embraces a fire-resistant wood-based material and a method for producing it.

A ceramic or composite coating is prepared from a mixture of a fire-resistant binder and an inorganic filler such that the mixture is suitable to be applied as a coating to a substrate, can be cured in situ, and protects the underlying substrate to which it is applied. In one example, the inorganic filler includes fly ash, where a mix ratio of the inorganic filler to the fire-resistant binder is from 1:1 to 9:1 by weight. The mixture can be cured in air at room temperature to form a composite coating on wood, metal, composites, and other substrates. High temperature processing can convert the composite to a ceramic.
