Abstract: A system and method of embedding a radio frequency identification RFID tag on tubular strings, pipes, or casings by machining a groove or indention towards the end of the fadeaway of the upset. Because the RFID tag is permanently affixed to the coupling, the pipe is capable of being monitored or tracked at various points in its storage, travel, or use.

Abstract: A casing coupling has a taper which is different from the taper of a standard API Pin. The coupling has a thread pitch diameter which is increased relative to that of a standard API coupling but which still mates with a standard API pin.

Abstract: A threaded connection for tubing having a pin connection with external, tapered buttress type threads, preferably with a one inch per foot thread taper, the pin threaded portion having seven threads per inch. The connection also includes a box connection having complementary internal threads threadedly engaging the pin, the box connection having a comparable pitch and thread taper.

Abstract: A threaded connection for use on oil field tubular. The connection has a dual tapered thread comprising a dual helical thread having a first, straight threaded portion and a second, angled portion, the threaded connection comprising a pin connection and a box connection both of which have thread-free sections. The thread-free section on the pin and the box are comprised of frustoconical surfaces and cylindrical surfaces. The thread-free section of the pin in addition to having a frustoconical surface and a cylindrical surface has an annular, radially outwardly radiused protrusion which, when the box and the pin connection are made-up is in interference engagement with the frustoconical surface in the box.

Abstract: A threaded, coupled connection having tapered, buttress-type threads, the threaded portions of the connection having a thread pitch of seven threads per inch. Preferably the pin threads of the coupled connection are pull-out threads.

Abstract: A method of recovering hydrocarbons from shale formations wherein a borehole is drilled under underbalanced conditions into a hydrocarbon-containing formation and, following fracturing with a cryogenic liquid, hydrocarbons released from the fractured formation are produced and recovered.

Abstract: A system and method for performing machining operations on first and second ends of an elongate workpiece, the system comprising a support for the workpiece which has first and second, spaced sides, each of which has first and second spaced ends, a first machining tool disposed proximate the first end of the first side for performing a first machining operation on a first end of the workpiece, a second machining tool being positioned proximate the second end of the second side for performing a second machining operation on a second side of the workpiece, the first and second machining tools being mirror images of one another.
