A process for forming a particle carrier system includes supplying a particle carrier, the particle carrier having a surface and modifying the particle carrier surface to include a first ionic functional group. The process also includes chemically binding the first ionic functional group on the particle carrier surface to a first ionic molecule.

Particles for carriers and tracers

The method includes gathering field data of a formation, preparing samples of brine consistent with the composition of the formation brine and the injection brine, dead crude oil, and live crude oil, and characterizing the properties of crude oil samples. The method includes preparing samples of reservoir rock and characterizing the properties of the rock samples of the formation. The method includes measuring the contact angle of surfactant/formation brine/formation rock/formation crude oil samples at ambient and reservoir conditions and measuring the interfacial tension of the sample. The method includes characterizing the HLD properties of each surfactant. In addition, the method includes performing formulation targeting HLD=0 for a mixture of surfactants, performing laboratory evaluation of the HLD=0 formulation of the mixture of the surfactants to obtain values of oil recovery number, and testing the HLD=0 formulation of the mixture of the first and second selected surfactants in the formation.

Methodology for down selection of surfactant formulations

A method includes forming an ionic liquid-based product, the ionic liquid-based product including an ionic liquid and mixing the ionic-liquid based product with a fluid. The method also includes injecting the fluid mixed with the ionic-liquid based product into a formation as part of an Improved Oil Recovery (IOR) application.

Ionic liquid-based products for IOR applications

Compositions and methods of using of such compositions to, for example, inhibit of the formation of gas hydrate agglomerates are provided. In one embodiment, the methods comprise: introducing a low-dosage hydrate inhibitor additive into a fluid, wherein the low-dosage hydrate inhibitor additive comprises a quaternary or tertiary ammonium cation moiety, a lipophilic tail, and a sulfonate anion moiety; and exposing the low-dosage hydrate inhibitor additive to a temperature above about 200&#xb0; F.

High temperature hydrate inhibitors and methods of use

Compositions and methods of using of such compositions to, for example, inhibit of the formation of gas hydrate agglomerates are provided. In one embodiment, the methods comprise: introducing a hydrate inhibitor composition comprising a compound into a fluid, wherein the compound comprises two hydrophobic cation moieties, a lipophilic tail, and two linking moieties.

A method of performing a squeeze treatment comprises pumping a treatment fluid under pressure through a wellbore into a subterranean formation, wherein the treatment fluid includes a hydrogen sulfide scavenging compound that adsorbs onto the subterranean formation in a region around the wellbore. Production fluids are then allowed to flow from the subterranean formation into the wellbore, wherein the production fluids contact the adsorbed hydrogen sulfide scavenging compound as the production fluids flow through the region around the wellbore, and wherein the production fluids contain hydrogen sulfide that reacts with the hydrogen sulfide scavenging compound to reduce an amount of hydrogen sulfide in the production fluids before the production fluids flow into the wellbore.

Squeeze treatment for in situ scavenging of hydrogen sulfide

Low-dosage hydrate inhibitor ('LDHI') compounds comprising multiple lipophilic tails and a hydrophilic head may be employed into fluids to inhibit agglomeration of hydrates, among other things. Suitable hydrophilic heads may include quaternary or tertiary ammonium cation moieties, and combinations thereof. Such LDHI compounds in some embodiments may include reaction products of DETA and/or other amines, fatty acid(s), and, optionally, alkyl halide(s). Compounds according to some embodiments may be employed in fluids in various environments, such as a conduit penetrating a subterranean formation, or a conduit carrying fluid in an industrial setting.

Multi-tail hydrate inhibitors

Disclosed herein are beta-amino ester surfactant compounds and compositions useful in applications relating to inhibition of gas hydrate agglomerates in the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compounds and compositions as gas hydrate inhibitors, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.

Beta-amino ester gas hydrate inhibitors
