摘要:
A method of forming a subterranean well and a method of reducing lost circulation in a subterranean well while drilling the subterranean well are disclosed. The methods include using multi-component fibers as lost-circulation materials. The multi-component fibers having external surfaces and include at least a first polymeric composition and a second polymeric composition. At least a portion of the external surfaces of the multi-component fibers includes the first polymeric composition, which at least partially adhesively bonds the mud cake formed during the method.
摘要:
A metal matrix composite is provided, including a metal, inorganic particles, and discontinuous fibers. The inorganic particles and the discontinuous fibers are dispersed in the metal. The metal includes aluminum, magnesium, or alloys thereof. The inorganic particles have an envelope density that is at least 30% less than a density of the metal. The metal matrix composite has a lower envelope density than the matrix metal while retaining a substantial amount of the mechanical properties of the metal.
摘要:
A method is disclosed that includes contacting a hydrocarbon-bearing formation with a treatment composition comprising solvent and a fluorinated polymer. The fluorinated polymer includes: a first divalent unit represented by formula (I): wherein Rf represents a fluoroalkyl group having from 1 to 8 carbon atoms; each R1 is independently hydrogen or methyl; Q is a bond or —SO2—N(R)—, wherein R is alkyl having from 1 to 4 carbon atoms; and m is an integer from 1 to 11, a second divalent unit comprising a poly(alkyleneoxy) group; and a third divalent unit comprising a pendant ionic group. The solvent includes not more than ten percent by weight methanol and not more than 25 percent by weight water, based on the total weight of the solvent, and/or the solvent solubilizes or displaces brine in the hydrocarbon-bearing formation. Treated hydrocarbon-bearing formations are also disclosed.

Sized short alumina-based inorganic oxide fiber comprises, based on the total weight of the sized short alumina-based inorganic oxide fiber: from 0.1 to 15 percent by weight of a size resin comprising a polyamide; and from 85 to 99.9 percent by weight of short alumina-based inorganic oxide fiber. Methods of making the sized short alumina-based inorganic oxide fiber and compositions comprising the sized short alumina-based inorganic oxide fiber in a polymeric matrix are also disclosed.
摘要:
A film includes a polymeric material and a plurality of particles dispersed therein. The polymeric material includes a plurality of elongate polymeric elements oriented along substantially a same first direction and interconnecting the particles. A ratio of a volume of the plurality of particles to a volume of the polymeric material is at least 5. An elongate portion of at least a first elongate polymeric element in the plurality of elongate polymeric elements may conform to and be bonded to a first particle in the plurality of particles along an entire length of the elongate portion. The first elongate polymeric element may extend from the elongate portion at least to a second particle in the plurality of particles.
