Abstract: A mandrel for mounting a stabiliser to drilling or casing drilling or running casing tubulars. The mandrel may be formed of a base component that is one of an elastomer, semi-crystalline or amorphous polymer, a thermoset material, or a cross-linked material. The mandrel may be formed or repaired by melting a base material in a high temperature melter and delivering it to a mould placed around a drill pipe etc. A stabiliser may be formed on a sleeve by covering the sleeve with a dissolvable substance, moulding the stabiliser over the sleeve, and separating the sleeve and stabiliser so that it can freely rotate relative to the sleeve. A stabiliser for a well tubular having a cylindrical body about a well tubular having stand-off ribs extending radially outwards from the cylindrical body and a protruding ring configured to run circumferentially around and extend radially outwards from the body.

Abstract: The present invention is directed to a tubular centralization system for completing oil, gas, geothermal and other types of wells where the temperatures may be high or the side loads are high, or both. A centralizer has a ring-shaped main body having an inner surface and an outer surface, with a central axis of rotation that passes through the open or hollow centre of the ring from a first open end to a second open end. A plurality of elongate blades extend from the outer surface of the body with each blade forming a wave form with at least two peaks and troughs along the length of the blade.

Abstract: The present invention relates to derivatives of known active pharmaceutical compounds. These derivatives are differentiated from the parent active compound by virtue of being redox derivatives of the active compound. This means that one or more of the functional groups in the active compound has been converted to another group in one or more reactions which may be considered to represent a change of oxidation state. We refer to these compounds generally as redox derivatives. The derivatives of the invention may be related to the original parent active pharmaceutical compound by only a single step transformation, or may be related via several synthetic steps including one or more changes of oxidation state.

Abstract: The invention relates to an identifiable bullet and methods for making an identifiable bullet. In one embodiment, the bullet has a generally circumferential body that tapers from a rearward end toward a forward end. A generally circumferential bore extends from an orifice on the forward end into the body at least part of the way between the forward end and the rearward end. The end of the bore opposite the orifice includes a polymeric material support surface. A polymeric material is placed between the polymeric material support surface and the forward end. The polymeric material may include a user identifiable marker for allowing a user to identify the bullet when viewing the forward end. Alternatively, the polymeric material may cover a user identifiable marker and seal the user identifiable marker in the bore. A user may identify the bullet by viewing the marker from the forward end of the bullet.

The journal (2; 15) may be of a substantially greater length than the length of the rotatable tool (18) to facilitate lubrication and cooling. Alternatively removable stop collars (30; 31) are secured adjacent the ends of a journal (28) formed on the drill pipe (25). Methods of forming the journal surface (2; 15) during manufacture of a drill pipe are disclosed. There are also disclosed methods for reconditioning an existing drill pipe (20) to form a journal (21) thereon.
