| 161 | FRICTION REDUCING WEAR BAND AND METHOD OF COUPLING A WEAR BAND TO A TUBULAR | EP10714737.3 | 2010-04-07 | EP2417324B1 | 2017-05-17 | BUYTAERT, Jean; MILLER, Eugene, Edward; HINING, Ira, Eugene |
| In one embodiment, a wear band comprises a rotating element having a bore receivable on a tubular, the bore comprising first and second bore portions slidably receiving first and second sleeve bearings. Outer surfaces of the sleeve bearings slidably engage the bore portions and the bores of the sleeve bearings slidably engage the tubular. A first stop collar and a second stop collar may be received on the tubular to together straddle the rotating element and sleeve bearings to longitudinally secure the rotating element in a position on the tubular. The tubular may be included within a tubular string run into a borehole or into the bore of an installed casing, such as in casing while drilling. The rotating element provides stand-off between a tubular and the wall of a bore, reduces frictional resistance to longitudinal sliding and also to rotation of the tubular string within the bore. | ||||||

| A technique facilitates the accumulation and analysis of data related to a subterranean formation. An arrangement of different types of sensors is mounted on a collar utilized in accumulating data on the subterranean formation. The sensors are operable in combination to improve the image quality of data obtained with respect to the subterranean formation. Certain applications utilize an arrangement of sensors comprising at least one of each of an electromagnetic sensor and an ultrasonic pulse-echo transducer. A stabilizer or stabilizers may be used to precisely orient and position the sensors within a wellbore. | ||||||

| A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. The support sleeve abuts but does not invade the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers. These tools enable debris to be removed from a wellbore. At least one locking clamp is attached to the cylindrical portion next to a said centralizer. The locking clamp prevents the support sleeve from moving longitudinally along the drill pipe joint. | ||||||
