API RP 13L:2003 pdf download.Recommended Practice for Training and Qualification of Drilling Fluid Technologists.
4 Principle
This document is a recommended practice (RPI and seeks to foirnaliie the specific knowledge base. professional skills. and application skills needed to ensure the competency and proressionalism of individuals working in the drilling fluids industry. Drilling fluids technologists should use this RP as an outline to self-determine an gaps in leaniing and seek to improve their skills. A company contracting the service uf a cfrilling fluids technologist should use this recommended practice as a checklist of knowledge that a technologist should be able to demonstrate pealiciency in applying.
5 Procedure
5.1 ORIGINS OF DISCIPLINES AND SUB- DISCIPLINES
The drilltng fluids disciplines and sub-dLsciphncs were developed from a review of the typical curricula followed by drilling fluids service companies in their basic mud school. The topics as listed in Appendix A were used as a Inimework ftw dcseloping the guidelines that turns the normative portion of this standaol. Each sub-discipline was divided into appropriate tasks and those tasks were assigned breath of knowledge statements needed to obtain minimum competency. The drilling fluid technologist discipline is broken into six sub- disciplines and each sub-discipline is described by tasks and specilic skills to demonstrate proficiency and knowledge in that task. for ease of reading, the tasks and skill set are placed in a table format
