UROS Under-Reamed Offset centralizers are unveiled for under-reamed well sections. They’re designed to optimize balance between drag resistive loads and performance required once in final position.
UROS is announced as “the answer to the oil industry’s need to reduce drag forces on run-in-hole through previously set casing before continuing into an under-reamed well section.”
The centralizers are declared to significantly reduce initial insertion forces — a characteristic of bow-type centralizers. They also deliver a substantial reduction in running forces when passing through previously set casings. Once through the compressed stage, UROS reverts to normal centralizer operation in open hole with its bows regaining their nominal outer diameter to maximize standoff.
Additional UROS Under-Reamed Offset data are free.
