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.

ring compound materials in the oil composed of carbon, hydrogen, sulfur, nickel and other trace materials. Asphaltenes are mostly very small platelets (35 A) suspended by micelles of maltenes and resins and carried through the oil. They precipitate by agg

n: see residuals.

a fuel oil, normally with high sulfur and high viscosity. API gravity of about 10.5o. Also called Navey Heavy and Number 6 fuel oil.

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 process to convert hydrogen sulfide into elemental sulfur by selective oxidation.

n pi: the six air pollutants listed under NAAQS in the CAA: ozone, carbon monoxide, sulfur dioxide,lead. nitrogen dioxide, and particulate matter. Sometimes called conventional pollutants.

v: to remove sulfur or sulfur compounds from oil or gas.

n: a kind of gas remove system used for drilling sulfurous gas layer

n: protector that some pieces steel bdlts through sulfurizing are buckled on drill pipe and it is fixed with pin.

usually an oil with more than 1% sulfur.
