Standard Guide for Use of Dual-Wall Reverse-Circulation Drilling for Geoenvironmental Exploration and the Installation of Subsurface Water Quality Monitoring DevicesMore info
1.1 This guide covers how dual-wall reverse-circulation drilling may be used for geoenvironmental exploration and installation of subsurface water quality monitoring devices. The term reverse circulation with respect to dual-wall drilling in this guide indicates that the circulating fluid is forced down the annular space between the double-wall drill pipe and transports soil/sediment and rock particles to the surface through the inner pipe.
Note 1: This guide does not include considerations for geotechnical site characterizations that are addressed in a separate guide.
