What We Do

Drilling Engineers’ fleet of geotechnical drilling rigs—which includes three CME-55s, three CME-75s and a Geoprobe 7822DT—is well equipped for auger drilling. The company is able to outfit each rig with hollow-stem augers or continuous flight augers. Work crews can deploy a variety of sampling equipment in the hollow-stem augers: CME’s Continuous Core Sampling System, heavy-duty split spoon sampling, Shelby tubes and California barrels (standard and modified). The company’s fleet has the capacity to drill at angles.

Drilling Engineers, Inc. provides drilling services to a broad range of public and private sector clients. We offer our clients years of on-site experience, state-of-the-art equipment and attention to the needs of their project.



Over 50 Years of Experience.


Who We Are

Drilling Engineers was founded in 1965, just two short years after the Central Mine Equipment Company of Missouri rolled the first of the now-industry-standard CME-55s off its assembly lines. The drilling industry has changed a lot since then, and Drilling Engineers has matched every advance in technology with another year of experience.

Since its inception, Drilling Engineers has focused itself on training its field crews, then keeping those same crew members in the fold. Clients can trust this experience to get their project done when a Drilling Engineers field crew rolls onto a new job site.

Modern contaminant hydrology has brought us to the realization that decisions regarding management of subsurface contamination need to be based on an understanding of all contaminant phases (i.e., aqueous, non-aqueous-liquid, sorbed, and vapor) and the biogeochemical conditions in which the contaminants are present. The practical approach for collection and analysis of frozen-cores presented here represents an important new tool for improving that understanding. Uniquely, core samples frozen in situ before recovery can preserve pore fluids, volatile compounds, dissolved gases, redox conditions, mineralogy, microbial ecology, and pore structure. Furthermore, in situ freezing improves quality of recovered core by preventing materials from dropping out of sample liners during recovery to ground surface. Collectively, steps followed for collecting frozen cores are referred to here as cryogenic core collection (C3).

Because freezing provides effective field preservation, frozen cores can be processed efficiently under controlled laboratory conditions to resolve a broad spectrum of chemical, physical and biological characteristics. Critically, processing core in the laboratory simplifies field work and improves the resources (e.g., anaerobic chambers) that can be utilized in preparation of samples for analysis. Furthermore, laboratory processing frozen cores allows “production line” processing and analysis of large quantities of samples, referred to here as high-throughput core analysis.

Barge Drilling




Custom Drilling Barge designed for ease of transportation. Drilling and soil sampling for both Geotechnical and Environmental projects.

We designed the barge so that it could be transported with our equipment carrier; unload, assemble and load the drill in one day. 


We are licensed in:
