Methods for providing corrosion inhibition in conduits, containers, and wellbores penetrating subterranean formations are provided. In some embodiments, the methods comprise contacting a metal surface with a fluid comprising a corrosion inhibitor additive. In certain embodiments, the corrosion inhibitor additive comprises a compound comprising a hydrophobic cation moiety, one or more lipophilic tails, and a linking moiety.

Amidodiamine corrosion inhibitors

Methods and compositions for treating aqueous fluids that may be included in treatment fluids that are used for treating a subterranean formation. In some embodiments, the methods include: providing a treatment fluid including an aqueous fluid and a composition that includes an oxygen scavenger, a pH-adjusting agent, and a corrosion inhibitor, wherein the aqueous fluid is aerated; contacting a metal surface with the treatment fluid; and introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.

Methods and compositions for reducing corrosivity of aqueous fluids

Included are compositions, methods, and systems for producing and using winterized paraffin inhibitor solutions. An example composition comprises a paraffin inhibitor solution; and an additive comprising a first portion and a second portion; wherein the first portion is selected from the functional groups consisting of sulfo, phosphate, phosphonate, ester, carboxyl, hydroxyl, and any combination thereof; wherein the second portion is selected from the functional groups consisting of linear alkyl, branched alkyl, alkyl phenyl, ethoxylated branched alkyl, propoxylated branched alkyl, and any combination thereof.

Additive to decrease the pour point of paraffin inhibitors

Generally discussed herein are systems, devices, and methods for improved automatic toll generation. A system can include one or more cameras positioned to capture images of vehicles passing through a toll station, vehicle detection and classification circuitry to receive an image of a vehicle from the one or more cameras and execute a first machine learning (ML) model to classify the vehicle, axle count circuitry to, in response to receiving data from the vehicle detection and classification circuitry that a vehicle was detected, execute a second ML model to classify a number of axles of the vehicle for determining a toll charge, and toll circuitry to issue the toll charge based on the classified number of axles.

Architectures for vehicle tolling

A method for inhibiting erosion (wear)-corrosion of downhole components in a secondary lift system, the method comprising: introducing a corrosion inhibitor and a lubricating agent into a wellbore; allowing the corrosion inhibitor and the lubricating agent to mix with a produced fluid to form a mixture; and recovering the mixture from the wellbore through a production tubing, wherein the corrosion inhibitor and/or the lubricating agent contact one or more of the downhole components of the secondary lift system. A system for inhibiting wear in secondary recovery comprising: a casing disposed in a producing wellbore; a production tubing extending into the casing; a downhole equipment disposed in the production tubing, wherein the downhole equipment comprises at least one equipment selected from the group consisting of a sucker rod, a plunger, and an electrical submersible pump; a treatment fluid for introduction into an annulus disposed between the casing and the production tubing.

Wear inhibitor for oil and gas production

Compositions, treatment fluids, and methods for providing corrosion inhibition in subterranean operations, pipelines, and other related operations are provided. In one embodiment, the methods comprise providing a tagged corrosion-inhibiting additive that comprises an imidazoline-based compound bonded with a detectable moiety; and introducing the tagged corrosion-inhibiting additive into at least a portion of a subterranean formation or pipeline.

Tagged corrosion inhibitors for use in subterranean operations

Compounds comprising multiple hydrophilic heads and a lipophilic tail may be contacted with a metal or other surface so as to adhere to the surface and inhibit corrosion, among other things. Suitable hydrophilic heads may include quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such corrosion-inhibiting compounds may be introduced into a wellbore penetrating at least a portion of a subterranean formation, for instance in oil and/or gas recovery operations and the like, whereupon the compound may adhere to a metal or other surface downhole so as to inhibit corrosion of the surface. These compounds may be employed in various other environments, such as any metal or other surface that may be exposed to corrosive conditions.

Multiple hydrophilic head corrosion inhibitors

A method of controlling corrosion in a subsea pipeline is disclosed which includes supplying a low dose inhibitor stream (LDHI) comprised of a quaternary amine and drying with a desiccant.
