Title: Methods for using a formation tester
Inventor: MCGREGOR MALCOLM DOUGLAS
IPC: E21B49/08
Filed: 2005-05-23
Abstract: A method of testing a downhole formation using a formation tester on a drill string. The formation tester is disposed downhole on a drill string and a formation test is performed by forming a seal between a formation probe assembly and the formation.

Title: Fluid pressure activated pipe coupling comprising folded sleeve secured by clamping rings
Inventor: SILVERTHORNE NOEL
IPC: F16L13/14
Filed: 2007-08-03
Abstract: A coupling for coupling together pipes 11,12 comprises a tubular sleeve 6 defining a socket for receiving a deformable pipe 11,12 to which the coupling is to be connected. An outer coupling body 1 extends around and defines a substantially annular chamber 10 with a main central portion (9, figure 1) of the sleeve 6. The chamber is sealed and can be pressurised by introduction of a fluid through an inlet 5 communicating with the chamber 10. The main portion of the sleeve 6 is inwardly compressible by pressurisation of the chamber 10 to grip the pipe 11,12 within the socket. At least one end (7,8, figure 1) of the sleeve 6 is folded over a corresponding end 2,3 of the outer member 1 such that it is disposed outwardly of the first portion (9, figure 1). A clamping ring (15, figure 4) clamps said end of the sleeve 6 against a generally outwardly facing surface of the outer member 1 so as to resist its outwards deformation. Increased pressure in the chamber 10 thus serves to increase the clamping force applied by the clamping ring (15, figure 4) thereby providing for a secure sealing arrangement.
