Abstract

A stop collar for mounting to a downhole tubular includes: a cylindrical housing having a threaded inner surface and a tapered inner surface; a compressible slip ring having teeth formed in an inner surface thereof and a pair of tapered outer surfaces; a cam ring having a tapered inner surface; a seal receivable in the housing; a cylindrical bolt having a threaded outer surface. A natural outer diameter of each ring is greater than a minor diameter of the threaded surfaces. Screwing the threaded surfaces of the housing and the bolt is operable to drive the tapered surfaces together and compress the seal, thereby compressing the slip ring such that the teeth engage a periphery of the tubular and energizing the seal into engagement with the periphery of the tubular.
