Outlines methods and procedures for the handling and use of inhibited hydrochloric acid for oilfield applications. Includes general considerations when using inhibited acid in wells, such as material and equipment checks, acid solution preparation, acid solution pumping and injection, and return fluids handling; field testing of 15% or less hydrochloric acid solution for presence or absence of corrosion inhibitors; and dispersibility tests for corrosion inhibitors in oilfield acids.
