DRILL STRING RFQ CHECKLIST

Drill String RFQ Checklist

A drill-string enquiry should describe the component, interfaces and drilling duty—not only nominal size and quantity.

01

Define every component

Separate drill pipe, HWDP, drill collars and BHA components into complete line items.

  • Size, weight and length
  • Steel grade and construction
  • Pin and box connections
  • Tool-joint and upset dimensions
02

Connect the order to the drilling program

Trajectory, loads and wear exposure influence configuration and verification.

  • Well profile and dogleg severity
  • Torque, tension and pressure envelope
  • Casing compatibility
  • H₂S and temperature conditions
03

Fix wear and inspection scope

Hardbanding and inspection requirements must be stated before quotation.

  • Hardbanding system and location
  • Body and end-area NDT
  • Connection gauging
  • Required service history if used
