acid corrosion inhibitor. Slows the acid attack on metal.

v: to treat oil-bearing limestone or other formations with acid for the purpose of increasing production. Hydrochloric or other acid is injected into the formation under pressure. The acid etches the rock, enlarging the pore spaces and passages through which the reservoir fluids flow. Acid also removes formation damage by dissolving material plugging the rock surrounding the wellbore. The acid is held under pressure for a period of time and then pumped out, after which the well is swabbed and put back into production. Chemical inhibitors combined with the acid prevent corrosion of the pipe. acid recovery plant n: plant for therecovery of sulfuric acid from acid sludge.

a substance that slows the reaction at the anode.

n: 1. a specific quantity of material that is processed, treated. or used in one operation. 2. in corrosion control, a quantity of chemical corrosion inhibitors injected into the lines of a production system. 3. in oilwell cementing, a part of the total quantity of cement to be used in a well. 4. in pipelining, a quantity of one weight or type of crude or liquid product pumped next to one of different weight or type.

slugging a chemical such as a biocide or a corrosion inhibitor in high concentration to accomplish either placement or super concentrated treating.

n: in corrosion control, the injection of a quantity of chemical corrosion inhibitors into the lines of a production

n: A kind of cationic surface active agent. Used for foaming agent of drill fluid and clay inhibitor of completion fluid.

n: liquid chemical compounds that are injected into lines carrying fluids that contain H2S, Most of these inhibitors are designed to coat equipment surfaces to physically isolate them from compressive substances. Others react with sulfur compounds to form less-destructive compounds.

n: a compound in which chromium has a valence of 6, e.g., sodium bichromate. Chromate may be added to drilling fluids eimer directly or as a constituent of chrome lignites or chrome lignosulfonates. In certain areas, chromate is widely used as a corrosion inhibitor, often in conjunction with lime.
