API RP 13L-2017 pdf free download.Training and Qualification of Drilling Fluid Technologists.
1 This standard is written in two parts. The first part is a summary of basic training and knowledge that an employee or contractor shall possess in order to be identified as a rig site drilling fluids technologist or rig site drilling fluids engineer. The first part covers basic skills as would be taught in an entry-level fluids school program. The second part covers a set of advanced skills that will be required in order 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. Normative References 2 The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. API Specification 1 3A, Specification for Drilling Fluid Materials API Recommended Practice 1 3B-1 , Recommended Practice for Field Testing of Water-based Drilling Fluids API Recommended Practice 1 3B-2, Recommended Practice for Field Testing of Oil-based Drilling Fluids Terms, Definitions, and Abbreviations 3 Terms and Definitions 3.1 3.1.1 breadth The basic knowledge common to all areas of drilling fluids technology needed by all drilling fluids technologists to demonstrate minimum competency. 3.1.2 drilling fluids engineer A drilling fluids technologist with an engineering, geoscience, or other appropriate science discipline degree from an accredited university. 3.1.3 drilling fluids technologist An individual with specialized knowledge of the application of drilling fluids during the drilling operation. 3.1.4 drilling fluids technician An individual skilled in the art of testing drilling fluids in the field or the laboratory.
5 Construction of the Recommended Practice 5.1 This document was developed from a review of the curriculums that are followed by drilling fluids service companies in their basic schools. The output from this, Core Skills, is found in 5.3. Five key areas are identified and further broken down into topics with the breadth of knowledge expected for that topic. Subsection 5.4 is structured in the same way and identifies additional skills required to work on complex wells. Skills identified in 5.4 are not taught as part of basic training, rather these are additive skills attained throughout a career as a rig site drilling fluids technologist or rig site drilling fluids engineer. Basic Industry Standards used for Generic Information 5.2 Recommended practices published by the API subcommittee on drilling, completion and fracturing fluids (SC 1 3) are the industry standards used for applying drilling fluids during a drilling operation. Two standards cover field testing procedures—API 1 3B-1 for water-based fluids and API 1 3B-2 for non-aqueous drilling fluids. Core Skills 5.3 This section describes the core skills that are expected of a drilling fluids technologist or drilling fluids engineer. It is expected that these skills will be taught in an introductory drilling fluids school program, and that skills will further develop with rig site experience and additional training.
• Able to describe the function of the shale shakers. • Familiar with the most current API shaker screen designation methodology. • Understands how to select shale shaker screens to maximize solids removal efficiency. • Understands the importance of shaker screen maintenance. • Able to describe the function of desanders and desilters and their likely cut points. • Able to describe the function of a mud cleaner and its likely cut points. • Able to describe the function of a drilling fluid centrifuge and its typical cut point range. • Able to describe the effects of fluid viscosity, density, and feed rate on solids-control equipment cut points. • Able to describe an assessment methodology for a rig-based solids control system. • Understands the importance of solids-control equipment processing rate versus fluid system circulating rate. • Able to describe the function of the rig degasser. • Able to describe the function of the cuttings dryer. • Able to describe the function, set up, and operation of a chemical (mixing) hopper. • Can describe the various types of pit agitation systems and understands the application differences and utilization issues.
