Costs associated with the abandonment of facilities or services, including costs for the removal of facilities and restoration of the land.

n: any chemical compound. one element of which is hydrogen, that dissociates in solution to produce free hydrogen ions. For example, hydrochloric acid. HCI, dissociates in water to produce hydrogen ions, H+, and chloride ions, CI-. This reaction is expressed chemically as HCI + H+ + CI- . See ion.

a reactive material with a low pH. Common oilfield mineral acids are HCl and HCl/HF.

n: It is made by adding suitable powder of lime or carbonate to the cement.

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.

n: compression of air or gas that exists when no heat is transferred between the air or gas and surrounding bodies (such as the cylinders and pistons in a compressor). It is characterised by an increase in temperature during compression and a decrease in temperature during expansion.
