The make up torque calculations for rotary shouldered connections in API 7G were based on lead based thread compounds, which have a friction factor of 1.0. Every application has its own characteristics, varying from large to small, with environmental conditions from high temperatures to high humidity, arctic blasts to desert heat.

Bestolife Zn50
Zinc-Based Thread Compound for All Rotary Shouldered Connections
Zn 50 is a zinc-based thread compound made with finely powdered metallic zinc. It contains 50% zinc as well as H2S and oxidation inhibitors. Meets the requirements of API RP SPEC 7: “Specification for Rotary Drill Stem Elements”. RECOMMENDED FOR tool joints, drill collars, and drilling and coring bits.
Bestolife Copper Supreme Special Blend
Non-Lead/Non-Zinc Thread Compound
Copper Supreme Special Blend has been developed as an answer to the environmental restrictions and exposure concerns associated with the use of lead and zinc drill collar/tool joint thread compounds. It contains copper flake combined with a proprietary blend of amorphous and synthetic graphites, along with oxidation and H2S inhibitors, in a high temperature base grease. In addition to the galling and seizing protection provided by the solids, it also contains a soluble extreme pressure package that is surface active (adheres to metal surfaces) and helps to provide the load carrying capability required by the high bearing stresses present in rotary shouldered connections.
Copper Supreme Special Blend has a torque correction factor of 1.1 (10% additional torque required) which will provide additional resistance to down-hole makeup as compared to lead or zinc compounds. It applies easily in a wide range of temperatures and conditions, is resistant to wash-out and will not harden or bleed excessively in storage.
RECOMMENDED FOR all drilling applications (rotary-shouldered connections), including high temperature environments. Also effective for use on open gear jackup legs.
Nonmetallic Thread Compound for Rotary Shouldered & Premium Self-Sealing Casing/Tubing Connections
Bestolife 4010 NM is the fourth generation of the highly successful Bestolife family of compounds designed and developed to address the environmental concerns, related to the use of thread compounds for rotary shouldered and premium connections, in ecologically sensitive areas of the world, such as the North Sea, Nova Scotia, Newfoundland, the South Atlantic, Alaska, and Sakhalin Island.
Bestolife 4010 NM combines the excellent low temperature application properties of Bestolife 3010 Ultra with superior downhole galling resistance and enhanced ecotoxicological properties to provide the ideal drill-string solution for all rotary shouldered (drill pipe/tool joints/drill collars) and many proprietary premium self-sealing casing/tubing connection applications, irrespective of offshore drilling location.
1.Applies easily to cold wet connections exposed to seawater in ambient temperatures as low as -40 °F/- 40 °C and yet provides optimum protection in the deepest, hottest holes. Will provide lubrication and protection to 600 °F/316 °C and the solids will protect to 1,000 °F/538 °C.
2.Has the ability to prevent galling of contact surfaces (including non-magnetic materials) under high bearing loads and to form a continuous gasket between the shoulders of a rotary connection during make-up. This is achieved through the innovative combination of graphite and other non-toxic materials, which interact to form a seal when compressed between seals, threads, and shoulders during make-up to provide performance properties which are equal to the very best heavy metal compounds. This gasket-like seal prevents connection wash-out, even under high internal fluid pressures and the combined loading of directional drilling, to provide maximum protection in the toughest conditions.
3.Conforms with ISO/DIS 13678 and API RP 5A3
4.Provides superior protection for the threaded connections of OCTG’s during transit and long term storage.
5.Meets the current (2007) OSPAR Commission Harmonised Mandatory Control Scheme (HOCNF) regulations for the protection of the marine environment of the North-East Atlantic/North Sea. Registered for use in the UK/Netherlands as an OCNS Category E Chemical and in Norway/Denmark as a Color Category Yellow Pipe Dope.
Casing/Tubing Connections
Bestolife 2000
High-Pressure / High-Temperature Thread Compound for Casing, Tubing, and Line Pipe
Bestolife “2000” is a non-lead, non-zinc alternative to API Modified. Extensive controlled testing, including full-scale make and breaks and sustained gas pressure tests, has demonstrated that “2000” conforms with ISO 13678 and API RP 5A3. “2000” will meet or exceed the listed performance objectives in ISO 13678 and API RP 5A3.
The major solid components are a proprietary blend of nonmetallic materials that are inert to chemical attack, such as occurs in sour gas environments and with CO2 injection, and stable to temperatures in excess of 500°F. Bestolife “2000” also addresses one of the major concerns in pipe yards and threading operations today – rejects due to pitting and corrosion. In a 700 hour salt fog spray test, “2000” has demonstrated corrosion protection that exceeds the performance of the leading storage compound in the industry.
The results of these tests show that Bestolife “2000” is not only an excellent “running” compound but can also provide superior protection during long term storage (contact manufacturer for application requirements).
Bestolife72733
High-Pressure / High-Temperature Thread Compound for Casing, Tubing, and Line Pipe
Bestolife 72733 exceeds the performance requirements and objectives outlined in API RP 5A3*, obsolete API BUL 5A2, and conforms to ISO 13678. This superior thread compound protects connections against galling during make-up and break-out, prevents leakage at temperatures in excess of 300oF, and withstands pressure to 10,000 psi.
Bestolife 72733 resists water absorption, disintegration and volume changes, and will not harden, dry out, evaporate or oxidize. It contains special corrosion inhibitors to resist pitting and discoloration of threaded surfaces during field use and storage.
Bestolife3010 NM Special
Nonmetallic Thread Compound for Rotary Shouldered Connections
Bestolife “3010” NM Special is the third generation of the highly successful Bestolife “3000”? family of compounds designed and developed to address the environmental concerns, related to the use of thread compounds for rotary shouldered connections, in ecologically sensitive areas of the world, such as the North Sea, Nova Scotia, Newfoundland, the South Atlantic, Alaska, and Sakhalin Island.
Bestolife “3010” NM Special combines the excellent low temperature application properties of Bestolife “3010” Ultra with superior downhole galling resistance and enhanced ecotoxicological properties to provide the ideal drill-string solution for all rotary shouldered connection applications (drill pipe/tool joints/drill collars), irrespective of offshore drilling location.
1.Applies easily to cold wet connections exposed to seawater in ambient temperatures as low as -49 °F/-45 °C and yet provides optimum protection in the deepest, hottest holes. Will provide lubrication and protection to 400 °F/204 °C and the solids will protect to 1,000 °F/538 °C.
2.Has the ability to prevent galling of contact surfaces (including non-magnetic materials) under high bearing loads and to form a continuous gasket between the shoulders of a rotary connection during makeup. This is achieved through the innovative combination of a variety of amorphous and synthetic graphite-based materials, as first used in “3010”, interacting to form a seal when compressed between the shoulders during make-up to provide performance properties equal to the very best heavy metal compounds. This gasket-like seal prevents connection wash-out, even under high internal fluid pressures and the combined loading of directional drilling, to provide maximum protection in the toughest conditions.
