Standard DS-1®, Volume 1 is a specification for newly manufactured tubular drilling products that provides the following:
- Specifications for two manufacturing levels: Standard (a reflection of the requirements from various API standards) and Critical (to allow for greater control and stringency when needed)
- Improved communication between operators and manufacturers by using the Standard DS-1® order form to eliminate errors
- Updated coverage, including metallurgical requirements for sour-service components
Standard DS-1®, Volume 2 provides risk based design resources for prevention of drilling equipment failure and includes the following:
- Tables of the capacities and dimensions you need for drill pipe, heavyweight drill pipe (HWDP), and drill collars
- Descriptions of the overload capacity calculations and failure-prevention processes
- Research on failure prevention topics like slip-cut severity and its impact on fatigue life, rig-equipment calibration and the effect it has on your uncertainty, and how inspection and design can and should work together
- Considerations for casing wear, stuck pipe, and other operational issues
- Curvature Index and Stability Index, tools a designer can use to lower the risk of fatigue failure and improve efficiency
Standard DS-1®, Volume 3 has given our industry an inspection standard for used tubular drilling products and contains:
- Six risk-based DS-1® inspection programs, called “Categories,” to aid the inspection buyer in aligning the inspection to the operation
- Many inspection methods with detailed procedures that guarantee the high quality results we want
- Clear and flexible acceptance criteria for many components including drill pipe and connections; new drill pipe sizes, grades, and proprietary connections; HWDP; drill collars; and subs
- Updated calibration controls and full length ultrasonic procedures to aid the inspectors in understanding and applying the requirements
