WellSET® Lost Circulation Treatment

Prevention of lost circulation by improving the wellbore strength is accomplished by designing and applying WellSET® treatments that increase the hoop stress around the wellbore.

The goal of WellSET treatments is to increase the hoop stress (and thus the wellbore pressure containment ability) in the near wellbore region. This is accomplished by placing a plugging material in an induced fracture that prevents further pressure and fluid transmission to the fracture tip, while at the same time widening and propping the fracture.

Summary Summary BaraECD® Fluid System and WellSET® Wellbore Strengthening Treatment Solve Deepwater Subsalt Drilling Challenges
Offset well data indicated that an operator would encounter a high-pressure subsalt sand between the base of salt at 19,200 feet (5,852 meters) and 19,700 feet (6,005 meters) measured depth (MD). A severely depleted sand was known to follow at 19,797 feet (6,034 meters) MD. Controlling equivalent circulating density (ECD) while drilling these sands would be critical to avoiding significant down time.
