Environmental Drilling

Holocene Drilling has invested heavily in strengthening our environmental drilling services through the hiring of managers experienced in the industry, developing crews and training specific environmental procedures, and procuring new equipment and technology to support the needs of our environmental clients. 

In the past two years we have hired two experienced managers to interface with our growing base of environmental consulting clients, train our crews, and manage environmental projects. All of our field staff, from senior drillers to new hires, undergo new training on procedures and requirements specific to environmental drilling. Environmental specific training is delivered during New Employee Orientation Training and throughout the year during our Quarterly Safety Meetings. Our crews are well versed environmental projects of varying complexity.
