Abstract: An orientable weight bar for a downhole tool includes a weight housing fixedly connectable to the downhole tool; an eccentric weight, and a weight lock. The eccentric weight is positioned in the weight housing. The eccentric weight has an offset mass along a radial portion thereof. The eccentric weight is rotationally and gravitationally movable within the weight housing to allow the offset mass to move to a weighted position within the weight housing. The weight lock is operatively connectable between the eccentric weight and the weight housing to secure the offset mass in the weighted position within the weight housing whereby, as the downhole tool advances through the wellbore, the eccentric weight gravitationally urges a portion of the downhole tool toward the bottom of the wellbore.

Abstract: A self-orienting swivel of a downhole tool and method. The swivel includes a top sub, a bottom sub, and a bearing assembly. The bearing assembly includes a bearing housing, bearings, and a lock member. The bearing housing has an uphole end operatively connectable to a second end of the top sub and a passage therethrough shaped to receive a bearing end of the bottom sub. The bearings are rotatably positioned in the passage of the bearing housing between the bottom sub and an inner surface of the bearing housing. The lock member is positioned in the passage of the bearing housing, and is fixedly connectable about the bottom sub. The lock member is receivably positionable in a receptacle of the top sub and rotatably movable therein whereby the bottom sub is rotatably positioned about the top sub.

Abstract: A thread protection system for a wellbore tubular includes a thread protector and a self-aligning bit. The thread protector has an insert portion at one end and a drive portion at an opposite end. The insert portion is engageable with an end of the wellbore tubular. The drive portion has a central cavity axially positioned about the thread protector and a plurality of pockets radially disposed about the central cavity. The self-aligning bit includes a platform with a central hub and a plurality of fingers extending perpendicularly from a driven side of the platform. The fingers are radially disposed about the central hub. The central hub is slidingly receivable in the central cavity. Each finger has a tapered tip slidingly receivable into the plurality of pockets. The self-aligning bit is rotationally drivable by a driver whereby the thread protector is removably connectable to the wellbore tubular.
