||Data Sheet 634, Revision A (Extensive), National Safety Council, 425 North Michigan Avenue, Chicago, Illinois 60611, USA, 1976. 3p. Illus. 11 ref.
||This data sheet describes methods and hazards of injecting acid solutions under pressure into predominantly carbonate formations, to dissolve some of the carbonate, thereby increasing the permeability of the formation and increasing the flow capacity of the well. Sections are devoted to: acidising methods; toxicity of inhibitors mixed with acids; characteristics of hydrochloric acid, hydrofluoric acid, acetic acid, formic acid, hydrogen sulfide; list of 14 rules for safe acidising procedures; personal protective equipment; first aid (deluge showers, etc.); dealing with acid spills.
