Dual-tube reverse circulation techniques are widely used in shallow to medium depth exploration projects and also for grade control purposes. In this course you will learn about the surface and downhole equipment that is used in dual-tube RC operations and the principles of operation of a range of sample collection and splitting systems commonly used.
This course is presented in 5 modules:
Module 1: Revision of general principles
Module 2: Dual-tube reverse circulation drillpipe
Module 3: Face sampling hammers, bits and shrouds
Module 4: Sample splitting systems
Module 5: Other key components of a dual-tube RC system
