Abstract:
A centralizer having asymmetrical bow springs defining a more gradual lead-in angle and a steeper retreat angle to reduce the required insertion and running forces. The centralizer comprises two end bands and a plurality of bow springs connecting the two shaped to gradually contact the surrounding hole or well casing. The bow springs are arranged such that a least two of them are asymmetric and positioned such that the apex of each is the same distance from an end band.

Claim (Index 38):
A centralizer configured to provide standoff forces in downhole hydrocarbon extraction applications comprising:\n a first collar and a second collar axially disposed a plurality of asymmetrical bowsprings wherein each of the plurality of bowsprings has an apex, a first end and a second end; wherein the first end is attached to the first collar and the second end is attached to the second collar; and the apex of at least one of the plurality of bowsprings and the apex of at least one other of the plurality of bowsprings are located at different distances from the first collar.
