2 PagesI sezz DELTA-TEQ system reduced downhole losses by 50% while running and cementing liners Challenges • Narrow operational window • Highly deviated wells • Uncertain geological information • Excessive downhole losses during casing runs Results • Reduced pressure on the formation while drilling • Lowered downhole surge pressures and ECD, downhole losses, NPT, and associated costs • Preserved wellbore integrity by reducing pressure spikes • Decreased time to run casing by reducing downhole losses A customer in the Norwegian sector of the North Sea needed to drill and navigate through complex geological formations and a low fracture gradient, where maintaining low equivalent circulating density (ECD) was essential in protecting the formation aga
