DS-1 Editorial

DS-1® Standards

Bureau Veritas developed the first edition of Standard DS-1® in 1992 to address the lack of industry standards for downhole drilling tools. As the industry developed and changed, Standard DS-1 was updated in second, third, and fourth editions based on our experience and our sponsors’ input. Bureau Veritas continues to keep pace with our industry, and the fifth edition of Standard DS-1® is set for release in early 2020.

Standard DS-1® is a global, industry-adopted standard for drilling and completions technology.

The four-volume set addresses the following:

Volume 1: New manufactured tubular drilling products
Volume 2: Risk-based design groups for prevention of equipment overload
Volume 3: Used tubular drilling and completions equipment
Volume 4: Inspection, assembly, and testing procedures for drilling and completion specialty tools

Standard DS-1® is comprehensive, technically sound, easy to implement, and flexible enough to adjust to a changing industry. Our in-house engineering team conducts extensive research to update and maintain Standard DS-1® as the leading failure prevention resource in drilling and completions. With our many years of experience in analyzing drill string component performance, Bureau Veritas is uniquely qualified to provide recommendations on drilling operational procedures, no matter the complexity.


DS-1 Volume 1 Drilling Tubular Product Specifications

Standard DS-1, Volume 1 applies only to newly manufactured tubular drilling products and provides the following:

• Specifications for two manufacture levels – standard and critical
• The introduction of “3-word implementation” to simplify order specifications
• Improves communication between operators and manufacturers by utilizing the Standard DS-1® order form to eliminate errors
• Provides a simplified format for obtaining the desired information

DS-1 Volume 2 Drill Stem Design & Operation

Standard DS-1, Volume 2 provides risk-based design groups for prevention of equipment overload and includes the following:

• Tables of drill pipe, heavy weight drill pipe (HWDP) and drill collars
• Instructions for specifying appropriate inspection for tools and proprietary tool joint connections
• Research notes on slip-cut severity and its impact on fatigue life and NC vs. REG connection fatigue performance
• Introduction of new methods of monitoring corrosion
• Expanded coverage of slip crushing issues
• Revised stress relief groove recommendations
• Considerations for casing wear

DS-1 Volume 3 Drill Stem Inspection

Standard DS-1, Volume 3 only applies to used tubular drilling products and contains:

• Six risk-based DS-1® inspection programs
• 31 DS-1® inspection methods with detailed procedures
• Categorized acceptance criteria for many drill pipes including standard drill pipe and connections, new drill pipe sizes, grades and proprietary connections, HWDP, drill collars and subs

DS-1 Volume 4 Drilling Specialty Tools

Standard DS-1, Volume 4 establishes an industry-wide standard for drill string specialty tools, which is defined as a component that operates in or is attached to the drill string having two or more parts. Examples are a kelly valve, mud motor, MWD, or jar. Coverage includes:

• Design limits and constraints
• Inspection, assembly, and testing procedures
• Return, repair, re-inspection, and restocking procedures
• Specific specialty requirements

DS-1 Bit Inspection Technical Standard

With bits of different designs coming from many different sources, it has always been difficult to ensure the quality of the bits without damaging the innovation or ignoring the variation within this important industry. For the first time, the industry has a way to guarantee that bit inspections are properly performed.

Unlike other standards that “cover” bits by simply referring to the wear ratings given in the IADC Drilling Handbook, the new DS-1 BITS is based on deep research with bit manufacturers, repair shops, and users. It covers fixed-cutter bits of many different designs, and it focuses on the areas that are important for performance. It gives clear definitions of “good” and “bad” which are based on good engineering and extensive experience. It gives you the power to prevent bit failures.

TS-1 Manufacturing Specification of Drill Pipe for Sour Service Application

The recently released Standard TS-1 specification outlines manufacturing requirements for drill pipe used in a sour service environment. Manufacturing drill pipe joints to this specification allows you to control material properties, testing, dimensions, and inspection requirements which will help mitigate sour service drill pipe failures.

Standard TS-1 has two pipe grades: TS-95 and TS-105 with minimum yield strengths of 95 ksi and 105 ksi, respectively, while the tool joints have a controlled yield strength of 110 ksi. The standard also covers NACE H2S testing for drill pipe tubes, tool joints, and welds, making this standard compliant with the NACE MR0175 standard.

Also features:
• Manufacturing requirements such as hardness values, hardness variation, chemical composition, testing frequency, etc. that are more stringent than the current Canadian IRP standard for sour service drill pipe
• Mill inspections including inspection methodology, standardization, imperfection tolerance, wall thickness tolerance, and more
• NACE H2S weld testing, which is unique to TS-1
• Manufacturing requirements that are in tabular format to facilitate ease of use
• Requirements on supplementary properties such as hardbanding, cold rolling of threads, phosphating, bench marks, thread protectors, Internal Plastic Coating (IPC), etc.

DS-1 Acceptance Criteria App
Criteria App

Our DS-1 app runs on iPhone®, iPad®, and Android™ devices.

This app provides DS-1 Volume 3 reference information. Volume 3 of DS-1 is our most popular standard; it gives you the inspection methods and procedures that are so critical to the success of your projects. It also has a big list of information about the acceptance criteria—good and bad—for tubes, tool joints, and connections.

We have an electronic version of Volume 3 that you can get, but sometimes you just need to know what’s good and what’s bad. So we’ve developed a reference app that gives you those criteria, both for iPhone and for Android. Check it out!

Edition Updates
DS-1-Addendums 10.28.19

By registering each volume of your Standard, you will receive:

  • Addendums, updates, and clarifications as they are published
  • Information on future editions

The Registration Form and Registration Number are included in the front of each volume. You may complete the form in your book, or DOWNLOAD the Registration form, and email the completed form to ds1@bureauveritas.com.

Guide to staying current:

First, determine which printing you have. This can be found at the bottom of the cover or on the title page. When a new printing is done, the previously issued addenda are incorporated into the manual.  Therefore, if you have a more recent printing, you would not need all of the addenda.


Over the past twenty-five years, the Standard  DS-1® has evolved from a simple drill stem inspection standard to the global reference for manufacture, design, and inspection of drill strings. The Fourth Edition expanded the scope to include a volume dedicated to specialty tools and provided significant updates for the existing volumes. As drilling technology changes, Bureau Veritas is committed to providing the best in technical standards to service the industry.

We are continuously seeking other industry leaders to be a part of future DS-1 edition sponsorship groups to guide the content of the Standard.

Each sponsor receives:

  • A seat on the Steering Committee which oversees development of the standard
  • 15% discount for public training courses for the latest DS-1 edition
  • Discounted price on purchase of volumes
  • Prominent recognition at the front of each volume

Each sponsor is encouraged to participate in the Steering Committee which is estimated at four days reviewing proposed content and two days attending meetings.
