摘要： A treatment fluid and method for water shut-off applications containing an amine-functionalized solid support, an epoxy resin, a second curing agent, and a carrier fluid. Prior to use of the treatment fluid, the amine-functionalized solid support has reacted with carbon dioxide to produce a carbamate-functionalized solid support. The treatment fluid is introduced into a geological formation with high-permeability pathways, curing the epoxy resin, and sealing these pathways.

摘要： Dissolving iron sulfide on the carbon steel tubing to yield chelated iron is achieved by treating the carbon steel tubing with a composition including an iron chelant and an additive. The additive includes at least one of an oxidizing agent and a base. A weight ratio of the iron chelant to the additive is in a weight range of 50:1 to 5:1.

摘要： A polymerizable chemical system for consolidating particulates in a subterranean formation including a liquid resin, a curing agent, and a permeability enhancing additive. The chemical system is a homogenous composition that polymerizes to forms a solid upon heating at a temperature greater than 60° C. Consolidating particulates in a subterranean formation includes providing a polymerizable chemical system comprising a liquid resin, a curing agent, and a permeability enhancing additive to a subterranean formation, and polymerizing the polymerizable chemical system to consolidate particulates in the formation to yield a porous consolidated particulates pack.

摘要： A method and a system for consolidating a subterranean formation are provided. An exemplary method includes injecting a water-in-oil emulsion into an unconsolidated subterranean formation, wherein the water-in-oil emulsion includes comonomers in an oil phase to form a polyurethane resin, and a catalyst in an aqueous phase. The method also includes allowing the polyurethane resin to cure to form a porous polymeric network.

摘要： A system and method of wellbore operations that forms notches into a subterranean formation that circumscribes a wellbore prior to fracturing the formation. The notches extend past the hoop stress regime that surrounds the wellbore so that fractures formed by fracturing are oriented in a designated plane. In one example, a fluid jet is used to form the notches, and which is discharged from a nozzle that rotates about a downhole tool. The nozzle is set in a sleeve that is rotatable about the downhole tool, and pressurized fluid is delivered to a plenum disposed on an inner surface of the sleeve. The nozzle is oriented oblique to a radius of the sleeve, so that the fluid being discharged from the nozzle generates a force that rotates the sleeve.

摘要： An apparatus includes a rotatable cylindrical housing and sensors. The rotatable cylindrical housing defines a longitudinal axis. The rotatable cylindrical housing is configured to couple to a rotor. The rotor is configured to rotate the rotatable cylindrical housing about the longitudinal axis. Each sensor includes a cylindrical body, a torque sensor, and a shaft that couples the cylindrical body to the torque sensor. The cylindrical bodies of the sensors are disposed within the rotatable cylindrical housing and are space apart along the longitudinal axis. The rotatable cylindrical housing and the cylindrical bodies of the sensors define an annular space for holding a fluid. Each torque sensor of the sensors is configured to, during rotation of the rotatable cylindrical housing, measure a torque applied by the fluid residing in the annular space to the respective cylindrical body to which the torque sensor is coupled via the respective shaft.
