摘要： Useful microemulsions have corrosion inhibitors in the internal phase and an external phase, where the corrosion inhibitor has a surfactant property that helps define the microemulsion. For example, the corrosion inhibitor itself may have its pH adjusted so that it also serves the role of surfactant. The corrosion inhibitors form microemulsions with particle or droplet diameters of about 10 to about 300 nm. The microemulsions may be oil-in-water, water-in-oil or bi-continuous.

摘要： Non-polymeric fatty acid drag reducing agents are described herein. These additives are useful to reduce drag in hydrocarbon fluids and multiphase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream, nor is grinding (cryogenic or otherwise) of the additive necessary to form a suitable drag reducing agent. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming. The drag reducing additives include fatty acids, alkoxylated derivatives of fatty acids, organic and inorganic salts of fatty acids and alkoxylated derivatives thereof, and esters of fatty acids and alkoxylated derivatives thereof, and mixtures thereof.

摘要： A method of inhibiting corrosion of a metal surface in an aqueous system having a pH of at least 6, comprising maintaining in the aqueous system, in an amount effective to inhibit corrosion, a water-soluble, organic-rare earth metal chelate which is derived from a rare earth metal having an atomic number from 57 to 71 and an organic chelant. The organic chelant provides not only water solubility but surprisingly enhanced corrosion inhibiting activity. The water-soluble, organic-rare earth chelates may be advantageously combined with other corrosion inhibitors such as zinc chelates, organophosphonates, phosphates, chromates, molybdates, and the like.

摘要： Hydrogen sulfide (H2S) and/or mercaptan scavengers are chemicals that remove H2S and/or mercaptans from gas, oil and water. Water-based formulations may be made and used employing scavenging compounds having the formulae: wherein each R1, R2, R3, and R4 are the same or different and are selected from the group consisting of hydrogen, an alkyl, an alkenyl, an aryl, an acyl, a halogen, a hydroxyl, a nitro, an alkyl ester, an aryl ester, an alkyl ether, an aryl ether, a hydroxymethyl, an anhydride group, an amino, and a sulfide. In one non-limiting embodiment the compounds (A) and (B) do not contain nitrogen atoms. Water-based formulations, such as those using a protic solvent with the above compounds, work well as H2S scavengers.

摘要： Mitigating or preventing corrosion of metal may be achieved in systems that are alkaline, such as carbon dioxide capture systems. The method may include adding an additive to a system wherein the system is at an alkaline pH; the system has both O2 and CO2 present; or the system is at an alkaline pH and has both O2 and CO2 present. The additive may be selected from the group consisting of: quaternary aromatic amines; quaternary alkyl substituted aromatic amines; and combinations thereof. The corrosion inhibiting properties of the additives may be increased by use of synergistic combinants. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： The use of neutral aqueous solutions of glyoxal (pH approximately 6 to 8.5) scavenges H2S that is present in natural gas and in oil better than glyoxal alone or base alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over glyoxal used alone. A buffer may be optionally used. In another embodiment, the combination of non-nitrogen-containing surfactants and glyoxal results in a significant increase in the reaction rate and the overall scavenging efficiency, i.e. capacity as compared to glyoxal used alone.

摘要： A composition of a wet hydrocarbon foaming agent including a siloxane can foam wet hydrocarbons. The siloxane wet hydrocarbon foaming agent advantageously foams hydrocarbons that have as little as 5 percent water present and those hydrocarbons having as much as 90 percent water present. The wet hydrocarbon foaming agent can be used in oil and gas production for gas lift and foam blocking applications. The foaming agent can also be used for clearing hydrocarbons from pipelines and other vessels used for transporting oil and gas.

摘要： Fluids viscosified with viscoelastic surfactants (VESS) may have their fluid loss properties improved with at least one mineral oil which has a viscosity greater than 20 cps at ambient temperature. The mineral oil may initially be dispersed oil droplets in an internal, discontinuous phase of the fluid. In one non-limiting embodiment, the mineral oil is added to the fluid after it has been substantially gelled in an amount between about 0.2 to about 10% by volume.
