Paper: Corrosion Control In Drilling Operations

Corrosion of drill pipe and protective casing strings is now recognized as a serious problem. In the past, very little attention was given to corrosion, due to the lack of understanding that most drill-pipe failures were due to corrosion. In areas where serious embrittlement failures occurred, treatments were designed to treat only the zones where hydrogen sulfide entered the drilling fluid. Through time, various types of treatments showed that corrosion could be controlled. It became evident that treating the entire depth of hole provided the most benefits. The recent shortage of drill pipe has accelerated attention toward saving pipe with a proper drillpipe corrosion program.
