Relief Well Pilot Borings
Geotechnology’s drill crews installed 60 pilot borings to provide well design information for the installation of 10-inch diameter relief wells along the east bank of the Mississippi River in northwest Mississippi. Boring depths ranged from 90 to 135 feet. Soil samples were collected at 2.5-foot centers through the planned screen intervals. Per USACE requirement, only potable water and biodegradable polymers were used as drilling fluids. Drilling and sampling operations were supervised by representatives of the Memphis District. Geotechnology, Inc. mobilized one rubber tired CME 750X ATV rig and a track mounted CME55HT drill rig for the project. Despite abnormally wet conditions, Geotechnology’s crews completed the project ahead of schedule and under budget.
