Some of the benefits of Sonic Drilling include: True continuous sampling, providing nearly undisturbed continuous cores. Recovery rates are higher with less sample disturbance than with conventional split-spoon. Drilling, sampling, and well installation is faster compared to cable tool, hollow stem augers, or other rotary methods. Core and case angled borings with great accuracy. Ability to drill through cobbles, boulders, sand, and weathered bedrock. Can advance casing to over 400 feet, construct wells and borings from 2 inches to 12 inches in diameter, and install barrier systems to a 36 inch diameter. Best drilling method for designing and installing CMT wells. Little or no investigation derived waste (IDW).
