摘要： Embodiments of the disclosure include compositions and methods that stabilize a injection fluid when exposed to reservoir conditions, reducing formation damage and increasing the amount of hydrocarbon recovered. Specifically, the formulation is a single-phase liquid surfactant package which comprises a surfactant and optionally one or more secondary surfactants. Also provided are methods of using the stabilized injection fluids in stimulation operations.

摘要： The present invention relates to an autonomous chemical treatment system and method for drilling and completion probes, so that it allows the probe to carry out chemical treatments in subsea wells, dispensing the need to use the WSSV, which has a limited treatment capacity due to tank volumetry, generally smaller that the marine probes.

摘要： A polyacrylamide friction reducer wherein the friction reducer contains surfactant functional groups, and wherein the polyacrylamide friction reducer is degradable, can be used for multi-functional, slickwater fracturing fluid projects. Under downhole conditions, the polymer degrades and releases the surfactant molecules to act as oil displacing agent to provide additional stimulation.

摘要： A method for obtaining substituted alkyl(meth)acrylamide includes reaction between (meth)acrylic acid or an ester thereof, and a primary or a secondary alkylamine. At least one of the two is at least partially renewable and non-fossil. The substituted alkyl(meth)acrylamide can have a bio-sourced carbon content of between 5 wt % and 100 wt % relative to the total carbon weight in the substituted alkyl(meth)acrylamide. The bio-sourced carbon content can be measured according to the standard ASTM D6866-21 Method B.

摘要： Proppant particles formed from slurry droplets and methods of use are disclosed herein. The proppant particles can include a sintered ceramic material and can have a size of about 80 mesh to about 10 mesh and an average largest pore size of less than about 20 microns. The methods of use can include injecting a hydraulic fluid into a subterranean formation at a rate and pressure sufficient to open a fracture therein and injecting a fluid containing a proppant particle into the fracture, the proppant particle including a sintered ceramic material, a size of about 80 mesh to about 10 mesh, and an average largest pore size of less than about 20 microns.

摘要： A novel surfactant composition that comprises of two surfactant components, a solvent, and water. The surfactant composition is added to a fracturing fluid, which is then pumped downhole into a subterranean formation where the novel characteristics of the fracturing fluid lend to improved oil production over the fracturing fluid without the surfactant composition.

摘要： A water-soluble polymer system for suspending proppant in a fracturing fluid is disclosed herein. The polymer system can be made with acrylamide, acrylic acid, a surfactant monomer, urea, a glycol ether, sodium hydroxide, and water and when mixed in a fracturing fluid with a proppant can form three-dimensional structures by hydrophobic association. The structures can also reduce frictional energy losses in the fracturing fluid system and can increase oil recovery after fracturing occurs.
