Full title and description

ISO 10407:1993 — Petroleum and natural gas industries — Drilling and production equipment — Drill stem design and operating limits. This International Standard adopts and modifies API Recommended Practice RP 7G (14th edition, August 1990) to specify properties, design principles and recommended practices for selection, use and limitation of drill-stem (drill string) components.

Abstract

Specifies principles and requirements for design and use of drill-stem elements and establishes operating limits and selection procedures for drill string members. The standard adopts API RP 7G with international modifications and covers selection procedures, operating limitations, classification and inspection guidance for drill pipe, tool joints, collars and related components.

Scope

Gives recommendations and procedures for selection of drill-stem members and for establishing operating limits that affect drill-string capability. Topics include selection steps for normal near‑vertical holes, effects of hole angle control, drilling fluids, weight-on-bit and rotary speed, operational procedures that reduce capability, classification and inspection of used drill pipe and tubing, welding statements for down‑hole tools, and classification of rock (roller) bits. The standard was prepared from API RP 7G and adapted for international application.

Key topics and requirements

• Principles for drill-stem (drill string) design and selection of members (drill pipe, tool joints, drill collars, heavy weight drill pipe, etc.).
• Step‑by‑step selection procedure for drill string in normal/near‑vertical wells.
• Operating limits and factors affecting performance: hole angle control, drilling fluids, weight, rotary speed and other operational constraints.
• Classification systems and inspection/identification procedures for used drill pipe, tubing and other drill‑stem elements.
• Guidance on welding on down‑hole tools and evaluation/marking of imperfections (inspection principles later expanded in Part 2).

Typical use and users

Used by drilling engineers, drilling contractors, well designers, inspection and integrity personnel, tool manufacturers and standards/regulatory teams in the oil & gas sector for design decisions, operational limits, inspection practices and equipment specification. Organizations use it for aligning company procedures with internationally recognized practices derived from API RP 7G.

FAQ

Q: What is this standard?

A: ISO 10407:1993 is an ISO International Standard that provides principles and recommended practice for the design, selection and operating limits of drill‑stem (drill string) components used in petroleum and natural gas drilling operations.

Q: What does it cover?

A: It covers selection procedures for drill string members, operating limitations (including effects of hole angle, drilling fluids, weight and rotary speed), classification and inspection practices for used drill pipe and tubing, welding guidance for down‑hole tools, and classification of rock bits; many inspection and classification details were later expanded in Part 2.

Q: Who typically uses it?

A: Drilling engineers, drilling contractors, equipment manufacturers, inspection personnel and standards/regulatory teams in the oil & gas industry use it for equipment selection, inspection criteria and operational guidance.

Q: Is it current or superseded?

A: ISO 10407:1993 is withdrawn and has been superseded/updated by later ISO deliverables; inspection/classification content was moved to ISO 10407‑2:2008. The record shows the standard as withdrawn (ISO lifecycle and reseller records list withdrawal actions and replacement by Part 2/related documents).

Q: Is it part of a series?

A: Yes — related work continued under the ISO 10407 series (for example ISO 10407‑2:2008 covering inspection and classification of used drill‑stem elements) and other ISO/TC 67 standards addressing drilling equipment and procedures.

Q: What are the key keywords?

A: Drill stem, drill string, drill pipe, drill collar, tool joint, inspection, operating limits, API RP 7G, drilling equipment.
