Providing geotechnical drilling parameters such as thrust, rotation, rate of penetration, and flush pressure will soon be incorporated into European Standard EN22574-15 and is already in BS5930. Having these parameters available gives geotechnical engineers another tool in the toolbox to characterize the subsurface. But I am not familiar with any drilling companies here in the US that can record and report this type of data. Does anyone use this technology in their practice? What kind of equipment is required on the drill rig to collect this data? Leave a comment, or tweet @geoprac.

This type of data recording is old hat in the oil & gas drilling biz (for example, see pason.com), so I would think it a fairly easy job to adapt to your smaller rigs. Not sure what “thrust” is–perhaps another name for “weight on bit”?
Thanks, for the insight, Howard. I think you’re probably right about the “thrust”. The geotechnical construction industry is no stranger to this technology either, particularly in grouting and cutoff wall applications.
