Stuck Pipe / Torque & Drag
Stuck pipe often is associated with well-control and lost-circulation events—the two other costly disruptions to drilling operations—and is a significant risk in high-angle and horizontal wells. Drilling through depleted zones, where the pressure in the annulus exceeds that in the formation, might cause the drill string to be pulled against the wall and embedded in the filter cake deposited there. Properly managing the lubricity of the drilling fluid and the quality of the filter cake across the permeable formation can help reduce occurrences of stuck pipe. Preventing stuck pipe can require close monitoring of early warning signs, such as: Increases in torque and drag, excessive cuttings loading, tight spots while tripping, lost circulation while drilling ahead. Turbo-Chem’s Turbo-Lube™ XLT, Drill Beads and Turbo-Spot™ can assist by eliminating and/or remediating these costly drill scenarios.
