Introduction: Need
Performance, Schedule, Cost
1. Unknown Performance of Connections- many
weights have no acceptable connector
•
Pipe Performance exceeding connection ratings
2. Supply Requirements: competitive bids, Multisource for meeting schedule requirements
3. Cost:



10-50% of the tubular cost
Failure- Financial Loss
Liability- life and property
Connection Reliability
Environment: Test Load
Envelope/ cycling, SLE, Failure
Points, Temperature
Installation: Torque,
RPM, Thread Compound
Application
Manufacturing (Drawing No./Overlay No)
Foundation: Design Related (FEA, ISO 13679, Design Calcs)
Design: Test to Dimensional, Makeup, and Load Extremes
Database Provides Dimensional specifications.
 Run Per Specification, within Service Load Envelope
Qualification has Eliminated Failures!
Methodology: Test
• Connection Qualification: DEA27, 5C5, 13679
– Manufacturers test budget can exceed $2.0 MM/yr
– Approx 6 major Suppliers/ 30+ connection types
– Over 15 years of Modern Data with Failures
• Database: Search Engine with Data Reduction
– Hierarchal Relational Database per Test Class
– Quick select dataset, with graphic output
– Output usable in Casing Design von Mises Format
Proprietary Classifications
• MTC-Metal to metal seal threaded &
coupled (Vam TOP, Fox, TC-II, HPC, 563,
Antares MS, APEX, NK-3SB, NS-CC …)
• SLH-Slim line high performance (SLX,
NJO, SLIJ II, Seal-Lock SF, ULT…)
• IFJ-Integral flush joint (STL, FJL, 511 …)
• SPT-Semi Premium Thread seal (Big
Omega, Boss...)
Connection Test Data
– Service Companies commit over $6MM annually
to connection testing; $40MM total/ 750 tests
– Testing: ISO13679, DEA27, API 5C5, User
Specification, Product Line qualification, CRA
– Robust: Service Load Envelope, Test Load
Envelope, Cycling, Temperature, Failure, Makeup
– Data is critically reviewed to delineate Class 4
Qualification test from Class 1 demonstration

Project Benefits
Short Term:
• Profit from $40 MM Testing performed over 15+ years
• Competitive Bid, Competitive Delivery
• Save Time: One Stop for Objective Connection Data
• Address Deepwater, Modern Performance Properties
Long Term:
• Network, Leverage, and Direct $6+MM Product
Development Effort
• Upgrade Casing Design Program: Include Connectors
• Lower Procurement Cost/ Reduced Trouble Time
Conclusion: Capture Learnings
Highly Leveraged Project Cost
Price Sensitive Product: 10% to 50% tubular cost
Primary Cause of Failure
Cost: Savings from a fraction of a single order
9-5/8, 53.5# @ $1000/ton, Connection cost: 50% tubular
reduced to 25% tubular: Equivalent to 100 joints
