The flush hole in a direction from an external side to an internal side comprises a surface at a rearward region that is curved at least at a radially inner portion to extend in an axial direction towards a forwardmost end of the adaptor to increase the resistance of the adaptor to stress concentrations whilst achieving a desired flow rate of flushing fluid flow into the internal bore.

| An assembly for use in subsurface drilling includes a downhole downhole probe supported by a centralizer. The centralizer comprises a tubular member that extends around the downhole probe. A wall of the centralizer is fluted to provide inward contact points that support the downhole probe and outward contact points that bear against a bore wall of a section of drill string. The downhole probe may be supported for substantially its entire length. | ||||||

| 67 | Fatigue resistant rotary shouldered connection and method | EP06251128.2 | 2006-03-02 | EP1705415A2 | 2006-09-27 | Muradov, Andrei |
Threaded connections are provided with a thread form that permits the construction of enlarged root radii between adjacent threads. Relatively coarse thread leads formed along conical surfaces with relatively extended tapers cooperate with relatively tall thread heights and an enlarged root radius (or radii) to produce a fatigue resistant, rotary-shouldered connection that can be assembled with reasonably attainable high torque forces. The ratios between the thread lead, measured in threads per inch, as the numerator, and denominators comprising the untruncated thread height of the thread, and/or the root truncation and/or the root radius (or radii) are maintained at low values compared to those existing in conventional prior art connections. The ratio of the untruncated thread height to the root radius (or radii) is also retained at a relatively low value as compared to that existing in many prior art configurations. The connection design produces an unexpectedly high resistance to fatigue damage or failure. The connection may be employed in any rotary-shouldered connection and is particularly effective in preventing fatigue damage in the stiffer components of drill stem assemblies including single shoulder and double shoulder drill collar connections.

| 68 | HEAVY WEIGHT DRILL PIPE | EP99920274.0 | 1999-04-30 | EP1078190B1 | 2006-07-12 | WILSON, Gerald, E.; MOORE, R., Thomas; TANG, Wei |
| A heavy weight drill pipe member is disclosed for use in drilling high angle and horizontal well bores in a corrosive environment. The heavy weight drill pipe member consists of a tubular member (10) with a longitudinal bore (29) therethrough, and includes connectors or tool joints (20, 22) attached at each distal end for connecting additional heavy weight drill pipe members. The tubular member (10) and tool joints (20, 22) are preheated, water quenched and tempered to obtain a unique combination of hardness, a yield strength and impact strength for improved resistance to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment. The tubular member (10) includes a plurality of wear pads or protectors (12, 14, 16) equidistantly spaced along the longitudinal axis of the tubular member (10) to reduce bending stress in the pipe by limiting the degree of bend when the pipe is placed in compression in a high angle well bore. To reduce the chances of differential pressure sticking of the pipe when the pipe is used in high angle or horizontal well bores, each wear pad or protector (12, 14, 16) is provided with spiral grooves (24) therein. Each wear pad or protector (12, 14, 16) may also be hard faced or hard banded to reduce wear. | ||||||

| La masse-tige décrite possède un collier de repêchage juste derrière l'extrémité mâle d'un joint de tige, laquelle extrémité possède une dimension réduite si on la compare à l'extrémité du joint femelle. En conséquence, l'outil est particulièrement bien adapté pour être orienté avec son extrémité mâle vers le haut dans la colonne de tubes de forage. Le rapport de résistance à la flexion (BSR) est amélioré en même temps que la masse-tige conserve de bonnes caractéristiques de ''repêchage'' et de ''surforage''. | ||||||

| Disclosed are methods of sampling a formation fluid, including flowing a formation fluid into a first flow line, measuring a first property of the formation fluid, opening a first valve to expose the formation fluid to a second flow line, pumping the formation fluid with a pump disposed in the second flow line, and directly measuring a second property of the formation fluid with a fluid ID sensor. The methods may further include closing a second valve while pumping to isolate a portion of the formation fluid and measuring a third property of the isolated formation fluid. Measuring the third property may comprise conducting a bubble point test. The methods may additionally include skimming contaminants from the formation fluid by pumping, and flushing the contaminants from the second flow line, which contaminants may be detected using at least one sensor. | ||||||
