Drilling activity in the U.S. showed the strongest gain of the year during August with 51 additional rigs making hole. International activity is strong, particularly in the North Sea. Now, with the prospect of peace between Iran and Iraq, oil prices could rise. These factors mean more drilling and a corresponding increase in well servicing. Whether producing or plugged, nearly all wells require a workover at some point to ensure optimum performance. But the process of killing well before workover can damage the formation by caking or the possible chemical incompatibility of weighted mud. In addition, the killing fluids and pumping equipment can be costly. Snubbing eliminates the expense and risk of killing the well. The snubbing - or hydraulic workover process - uses jointed tubing or drill pipe and a hydraulic snubbing unit to run tubing or pipe under pressure.
