Description / Abstract:

Scope and Definition:

With the Fourth Edition of Standard DS-1®, inspection and qualification of drill string components is specified in Volumes 3 and 4. Volume 3 addresses the inspection of drill string equipment consisting of a single piece with no component pieces. Examples include drill pipe, drill collars, subs and pup joints. Volume 4, first published with Fourth Edition, addresses drilling specialty tools, which are defined as a device that:

• can be run in a drill string or casing string and perform some function

• is assembled from two or more components, and;

• is complete in itself with no additional equipment needed for its function except possibly some external power or pressure source.

Examples of drilling specialty tools include mud motors, MWD, LWD, underreamers and safety valves.

This chapter (from section 2.3 onwards) gives instruction on how to order an inspection program under Volume 3. Section 2.2 below provides instructions on how to specify the qualification requirements for a drilling specialty tool under Volume 4.
