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 23):
The integral centralizer device of  claim 21 , wherein:\n the pair of collars comprise a first collar and the second collar, such that when the integral centralizer device is constructed, the first collar is the collar nearest each of the first ends of the bowsprings and the second collars is the collar nearest each of the second ends of the bowsprings; wherein, when radially compressed, at least one first end of at least one of the plurality of the bowsprings can travel axially in relation to the first collar.
