摘要： A bearing (10) for use in a downhole motor assembly having an inner race (12) formed as a unitary construction. The inner race (12) has an inner surface (14) defining a first diameter (D1) and an outer surface (16) defining an second diameter (D2) and a number of race-ways (18). The bearing (10) also has an outer race (20) having an inner surface (22) defining a first diameter (D3), an outer surface (26) defining a second diameter (D4) and a number of race-ways (28). Bearing elements (30) are provided in the raceways (18, 28) to couple the inner race (12) and the outer race (20) such that, in use, the inner race (12) and the outer race (20) can rotate relative to each other. The inner race (12) of the bearing (10) is configured so that an inner diameter of the inner race is outside a drill through of a downhole motor assembly.

摘要： A downhole tool (10) configured to condition a borehole (B) and deliver a settable material, such as cement slurry, into a borehole annulus (A) for securing and supporting a casing string (C) in the borehole (B) comprises a body in the form of tubular housing (12), a shaft (14) rotatably mounted within the housing (12), a head portion (22) and a drive arrangement (20). In use, borehole cleaning and cementing operations may be carried out by directing a drive fluid, such as drilling mud, through the drive arrangement (20) to drive rotation of the head portion (22) to clean or condition the borehole (b). A cement slurry or the like, may then be directed through the casing string (C) or via a cementing string (S) into the shaft (14), and through the drive arrangement (20), the fluid then being ejected from the head portion (22).

摘要： A completion system (10) comprises tubular components (22) coupled together to form a completion string (24). In-flow control devices (34) are provided to permit selective fluid communication between an internal bore (26) of the completion string (24) and the annulus (28). A reaming tool (38) is provided at a leading end of the completion string (24) and the reaming tool (38) is run into the borehole (12) with the completion string (24). The reaming tool (38) comprises a fluid-powered drive unit (40), a reaming body (42) and a reaming nose (43). In use, the string (24) is located in the borehole (12) and fluid is directed to the reaming tool (38) to facilitate reaming of the borehole (12). A second tubular in the form of a washpipe (44) extends through the internal bore (26) of the completion string (24) for providing fluid to the reaming tool (38). The reaming tool (38) is operable at a fluid pressure below a pressure which would activate the in-flow control devices (34).

摘要： A reaming tool in the form of reamer shoe (10) is adapted for location in a wellbore and comprises a substantially tubular mandrel or body (12) having a central bore (14) located about an axis (15). A cap or nose (16) is coupled to a distal end portion of the body (12) via a connection (18). The nose (16) defines an eccentric offset portion or lobe (20) which extends to a greater axial extent than the remainder of the nose (16). A weighting arrangement is provided, the arrangement adapted to balance the mass of the nose about a central axis of the shoe. The distal surface of the nose (16) comprises a substantially concave central portion (17). The nose (16) further comprises a projection or dimple (19) on an opposing side of the nose (16) from the concave surface.
