2. Thread Compounds Important Jobs: Seal Lubricate Protect

3. Thread Compounds Important Jobs: Rotary Shouldered Connections Tubing and Casing Pipe in Storage

4. — Rotary Shouldered Connections —

6. — Rotary Shoulder Connections — Thread Compounds Should: • Prevent metal to metal contact • Provide a leakproof seal for fluids • Limit make-up during drilling to prevent excessive stresses on threads • Prevent corrosion of threads • Ideally, breakout less torque than make-up • Leave no residue or plating at breakout

8. — Rotary Shoulder Connections — Compounds Need: • Ingredients that should mould into threads, produce a seal, and reduce thread contact • To be slick enough to lubricate threads during make-up but provide sufficient resistance to make-up under torque

9. — Rotary Shoulder Connections — Compounds Should Have: • Additives that are spherical in shape • As the joints are torqued, the additives are flattened & elongated bonding together on the shoulders of the pipe, preventing metal to metal contact • The circumferential make-up at given torque controlled by the compound type • Dispersed particles are compacted during make-up and do not stick together when broken out

10. — Rotary Shoulder Connections — Compounds Seal: • Sealing and galling prevention are most important functions of a thread compound • Metallic particles in the compound seal and protect the threads against galling • Non-metallic compounds rely on solids like Graphite, Talc, and others to seal and eliminate galling

11. — Rotary Shoulder Connections — Make-Up of Connections: • Torque required for make-up depends on the size and strength of tool joint • Optimum torque should be about 60% of torsional yield strength of tool joint • Make-up torque should be greater than the drilling torque but less than the torsional strength of the tool joint

21. — Rotary Shoulder Connections — Uncontrolled Make-Up: • When the make-up torque of the tool joint is less than the drilling torque, it can make-up down hole and may be difficult to breakout • Uncontrolled make-up down hole can damage a tool joint and cause a drill string to twist off down hole

30. — Rotary Shoulder Connections — Make-Up Lubricity: • Thread compounds need to have consistent frictional properties • Joints should be made-up the same amount every time • This will prevent make-up down hole • When joints are made up too far, severe damage can result • Drilling torque should be less than make-up torque

31. — Rotary Shoulder Connections — Breakout: • Ideally, breakout torque should be less than make-up torque • If a joint makes up down hole, the breakout torque can be higher than the make-up torque and the original make-up equipment may not be able to breakout the joint

32. — Rotary Shoulder Connections — Types of Compounds & Properties: • Lead based – • Lead provides seal, and make-up stress energy is absorbed • Can be used on both collars and pipe. • Zinc based – • Zn is a reactive metal, and can have problems when temperature and moisture are present • Can be used on both collars and pipe.

33. — Rotary Shoulder Connections — Types of Compounds & Properties: • Copper based – • can be used on collars and pipe • Can withstand higher temperatures than Lead or zinc • Non-Metallic – • additives take the place of metals to provide the seal • more environment & worker safe, non-reactive • non-hazardous for offshore

34. — Rotary Shoulder Connections — Environmental Compounds: • No metals – Lead, Zinc, or Copper • Ingredients that cause no harm to environment • Biodegradable components • Non-toxic to marine organisms • No labels required for disposal • No Toxicity Characteristic Leaching Procedure required

35. — Rotary Shoulder Connections — Environmental Regulations: • Offshore Drilling – Regulations are more strict • Worldwide – many countries are regulating the use of hazardous materials • Land rig waste disposal is becoming more regulated • Some companies are standardizing on the same thread compounds worldwide

36. — Rotary Shoulder Connections — API RP 7A1: • “Recommended practice for testing of thread compounds for rotary shouldered connections” • used to determine the frictional properties • API RP 7A1 is being incorporated into ISO 13678 and a new tester & test method are being developed • API RP 7A1 provides drillers with friction factors that help predict actual make-up and breakout torques required using API RP 7 G recommended torque

41. — Tubing & Casing Thread Compounds —

42. — Tubing & Casing Thread Compounds — Environmental Regulations: • API Modified – Lead/Zinc/Copper product recommended for use in Annex A - API RP 5A3 • API RP 5A3 – allows for different compounds that meet performance specifications

43. — Tubing & Casing Thread Compounds — Should Provide: • A long term seal on the threads to prevent leaks • Protection against galling on the threads • Protection against corrosion to the threads

44. — Tubing & Casing Thread Compounds — Environmental Regulations: • API Modified - Annex A of API RP 5A3 • reduced usage of this product due to heavy metal content • More environmental products are used mainly, either copper or non-metallic • Standardization by oil and tubular companies worldwide • Move towards environmental products is strong

45. — Threads in Storage —

46. — Threads in Storage — New Solutions: • Rusting threads in storage have been a major problem for all drillers • Thread compounds are seldom compatible with currently available storage compounds • BSC (Bestolife Storage Compound) was tested in the ASTM B117 Salt Spray Test, to over 4000 hours without any pitting or corrosion, and is compatible with most thread compounds

47. BESTOLIFE “4010” NM Twenty-First Century Thread Compound • Meets worldwide chemical regulations • Biodegradable & non-toxic • Good adherence under cold & wet conditions • Works on both rotary and tubular/casing connections • Provides long term storage protection
