A through inspection is the most cost effective way to catch a small defect that might otherwise cause the pre-mature failure of your string and loss of your well.
After a complete inspection
the following specialized services are
offered to inject new life into your
drill string.
Special tools developed
by Tuboscope enable us to reface and
damaged seal area on-field saving costly
down-time and enabling the drill string
to be used again immediately.
The careful bonding of hard metal like tungsten carbide to tool joint steel will protect the OD from down hole abrasion. Without such protection, the tool joint can wear until it becomes too thin to be safely run. Such wear also reduces the torsional capacity of the connection leading to significant expenses , especially if the drill string parts down-hole.
Drill collars, heavy weight drill pipe and other bottom hole assembly components are often protected with hard-facing as well.
The theory is to protect all the drill string components that make intermittent contact with the inner surface of the hole, especially in abrasive formations. The wear is more significant in open hole drilling than in cased wells.
When drilling through
casing it is important to minimize
wear to the ID of the casing. Properly
hard-faced tool joints when run with
proper drilling practices have proven to
cause less wear to casing than tong-cut
tool joints or even rubber drill pipe
and casing protectors run in the presence
of sand.
Metallurgical know-how every step of the way
The hard facing procedures and materials adopted by Tuboscope Inc., reflects the latest technologies in bonding one metal to another. The Selection of raw hard metals and sizing of hard facing particles is extremely critical. The temperature during pre-heat and welding is precisely regulated. The cooling procedure is as important to the success of the job as the welding itself. Collectively , no company can offer more background and experience in drill string hard facing than Tuboscope Inc.
Complete selection of Surface Materials
To meet customer requirements
, Tuboscope Inc., offers the most complete
range of materials and welding procedures
in the industry. From the very hard
surfaces required for certain open-hole operations
to several types of extremely smooth
surfaces applicable to cased hole drilling.
In other words , it is safe to say that you can trust your drill string hard facing needs to Tuboscope, Inc., the people who know pipe inside and out.
