offers a most economical solution: BIG OMEGA™, the efficient coupled connection, based on the rugged
V & M Omega thread profile.
BENEFITS
- Field proven
- Easy running
- Deep stabbing
- No cross-threading
Design principles and technical features
BIG OMEGA™ Casing can be delivered in OD’s ranging from 14 in. to 26 in. and in lengths corresponding
to API ranges 2 and 3 (including pup joints).
BIG OMEGA™ is a coupled connection.The pin thread is cut directly into the pipe.The risks associated
with weld-on connectors are eliminated.
Standard coupling OD’s are identical with API; they may be increased for higher grades and larger wall
thicknesses if matched internal pressure resistance is required. The standard coupling length is 10
5/8 in. (269,9 mm) as with API.
BIG OMEGA™ Casing is a mill threaded pipe. It is available in the quenched and tempered condition
in both API and V & M special grades.
BIG OMEGA™ Casing possesses the ruggedV & M-developed thread profile featuring:
- 3 TPI versus Buttress 5 TPI
- Taper 1:75 versus Buttress 1:12
- Bearing flank perpendicular to thread cone
- Stabbing flank 30°
- Crests and roots parallel to cone
- Enhanced thread height 0.0846 in. (2,15 mm) versus Buttress
- No cross-threading
- Quick running
- Easy stabbing
Field experience
More than 20 years have gone by since the delivery of the first casing string with BIG OMEGA™ connections,
an 18 5/8" string which was run in the Khuff Wells nearAbu Dhabi, U.A.E. Since then, internationally
proven and accepted, BIG OMEGA™ has been used widely by all major oil companies worldwide, e.g.:
- Europe (including the North Sea)
- USA and Canada (including theArctic)
- Africa
- SouthAmerica
- Middle East
- Far East
- China
- Australia
An internal torque shoulder (-IS option) whenever high torque and/or
high axial compression are to be expected.
