The reasons for the drill pipes failure as a result of interaction with formation water and killing fluids were analyzed. It was determined that the aggressiveness of killing fluids increases as a result of acid treatment of wells, which causes severe pitting corrosion. The main corrosive components of the killing fluids from the exploited wells determined by chemical analysis were chlorides. The determined residual life-time of the G105 drill pipe in the acidic killing fluid was only 16.65 days, indicating that their usage in acidic, highly mineralized killing fluids is unacceptable.
