API RP 13L PDF

This recommended practice (RP) is written in two parts. The first part is a summary of basic training and knowledge that an employee or contractor shall possess to be identified as a Drilling and Completion Fluids Specialist. The first part covers basic skills as would be taught at an entry-level drilling fluids training program. The second part covers a set of advanced skills that will be required to support complex wells at the rig site. Levels of understanding for both core and advanced skills have been generally outlined, but not totally defined.

The document was developed from a review of the curriculums that are followed by drilling fluids service companies in their basic schools and from input by industry subject matter experts. The output from this, “Professional Core Skills,” is found in Section 5. Ten key professional core skill areas are identified and further broken down into topics with the knowledge expected for that topic. “Advanced Professional Skills” found in Section 6 are structured in the same way and identify additional skills required to work on complex wells. Skills identified in Section 6 are not taught in depth as part of basic training; rather these are additive skills attained throughout a career as a drilling and completion fluid specialist and related disciplines.

The RP is not intended to establish certification procedures for drilling fluids personnel but is to be used for general guidance in evaluating training processes and evaluating the professional acceptability of drilling and completion fluids specialists.
