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 13) are the industry standards used for applying drilling fluids during a drilling operation. Two standards cover field testing procedures—API 13B-1 for water-based fluids and API 13B-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.This document is a recommended practice and seeks to provide guidance for the specific knowledge base, professional skills, and application skills needed to ensure the competency and professionalism of individuals working in the drilling fluids industry. Drilling fluids technicians, technologists, and engineers should use this document as an outline to self-determine any gaps in learning and seek to improve their skills. A company contracting the service of a drilling fluids technician, technologist, or engineer should use this recommended practice as a checklist of knowledge that a technologist should be able to demonstrate proficiency in applying.• Understands that most sedimentary formations have clay minerals present. • Understands that the type and quantity of clay present in drilled formations affects the drilling fluid properties. • Able to describe the difference between clay and shale. • Understands the fundamental interactions between water-based fluids and shales.• Understands the general definition of clays and their fundamental structure, i.e. crystalline silicate minerals smaller than 2 microns with layered structures combined in units. • Understands the different basic clay types and the potential role that each plays in drilling fluid technology. • Understands the four clay states of particle association.• Understands that clays are generally classified by their chemical composition and morphology. • Understands the differences between swelling and nonswelling clays. • Understands the reaction of the major clay types when exposed to water.• Understands the fundamentals of colloidal suspensions. • Understands the significance of the terms: dispersed, nondispersed, flocculated, and deflocculated. • Understands the differences between crystalline and osmotic swelling.• Understands the functions of clays in controlling viscosity. • Understands the functions of clays in filtration rate control and filter cake properties.• Understands the effects of electrolyte concentration on clay interaction. • Understands the effects of negatively charged polymers on clay reactions.• Understands the effects of adding dispersants and/or deflocculants on clays in water-based drilling fluids. • Understands how to manage viscosity and improve filter cake quality with the use of these chemicals.API RP 13L pdf download.
