Career Summary
Glen A. Collier’s career as a professional geologist spans over 40 years with experience developed in a number of geoscience specialties. His expertise includes base and precious metals exploration in a variety of geologic settings, environmental geology project management, and a wide range of hydrogeological investigations.
Mr. Collier’s formative years as a professional geologist were in minerals exploration. With a primary focus on carbonate-hosted base metal deposits, he also evaluated precious metals and massive sulfide prospects at locations throughout the United States. His proficiency in developing conceptual models for exploration, project planning, and managing high profile aggressive projects put him in the position of Senior Exploration Geologist over a regional office within four years after receiving his degree from the University of Texas. The office was tasked with exploration in the Mid-Continent area of the U.S. In the mid-1980s, with a grim outlook for metals prices, Mr. Collier resigned his position and returned to his home town of Nacogdoches, Texas. Upon his return, he became part-owner of a water well drilling company, and later became licensed as a Master Driller, while personally mapping the distribution of aquifers in East Texas. In 1991, his hydrogeological background led him to a position with an engineering firm that was anticipating implementation of Subtitle D of the Resource Conservation and Recovery Act, which targeted groundwater protection at municipal solid waste facilities.
In 1994, Mr. Collier founded Hydrex Environmental. Under his leadership, Hydrex expanded from a one-man company to a firm that today employs 25 – 30 employees and has a statewide footprint. Mr. Collier currently serves as Senior Hydrogeologist, Special Projects Manager, and Chairman of the Board.
Professional Career
Hydrex Environmental
Since its origin in 1994, Hydrex Environmental has grown to become a multi-discipline firm of geologists, hydrogeologists, biologists, environmental scientists, engineers and GIS specialists. The company now provides a full range of environmental services to industries and municipalities in Texas and adjacent states. Hydrex has maintained its regional presence by applying newly-developed technology in its projects. The company was the first in the East Texas to employ direct-push soil sampling technology. Its GIS mapping capabilities are unsurpassed in a company of its size. In 2015, Hydrex added the Drone Division. The utilization of small Unmanned Aerial Vehicles (sUAV), along with cutting-edge computer technology, allows for Hydrex to apply a variety of sophisticated mapping techniques. As Senior Hydrogeologist, Mr. Collier manages special or large-scale projects, particularly those related to groundwater availability and groundwater management. In these projects, he is able to rely extensively on his regional hydrogeological experience.
ETTL Engineers & Consultants
Hydrex Environmental resulted from Mr. Collier’s involvement with municipal solid waste (MSW) facilities that began in 1991, just prior to the implementation in Texas of Subtitle D of RCRA. Working for a regional geotechnical firm, he assisted in expanding the company’s landfill client base by offering his hydrogeological expertise along with engineering services. He conducted numerous groundwater characterization studies for new and expanding MSW facilities. He developed groundwater sampling and analysis plans and designed and installed groundwater monitoring systems throughout Texas. Concurrently, Mr. Collier performed geotechnical investigations for buildings, roads, and dam construction. He became experienced in environmental investigations, conducting Phase I and Phase II Environmental Site Assessments (ESAs). The Phase II ESAs included leaking underground storage tank projects as well as investigations of industrial sites.
SMD Drilling Company
In the mid-1980s, Mr. Collier became part owner of a drilling company based in East Texas. The company initially drilled oil wells for enhanced recovery in shallow fields, completing over 90,000 feet of drilling in a single year. The company was motivated to expand to water well drilling by the cyclic nature of the oil industry. During his involvement, Mr. Collier earned a Master Drillers license (Texas License No, 2910). He initiated a program of mapping groundwater-bearing, fluvial-deltaic sands of the Eocene in East Texas. Relying on his exploration experience, he worked with engineering companies and municipal water systems to determine the most favorable locations and well sites for groundwater production. Mr. Collier served on the advisory committee of a Texas Water Development Board study of areas in East Texas where groundwater conditions were potentially critical. The findings of the study were published in the February 1991 TWDB Report 327, “Evaluation of Ground-Water resources in the Vicinity of the Cities of Henderson, Jacksonville, Kilgore, Lufkin, Nacogdoches, Rusk, and Tyler in East Texas”.
Houston Oil & Minerals / Tenneco
While an undergraduate attending the University of Texas, Mr. Collier was employed in a part-time capacity by the Minerals Division of Houston Oil & Minerals Corporation (HO&M), which had recently opened an office in Austin. His duties consisted primarily of logging drill cuttings from the collection at the University of Texas Bureau of Economic Geology. The project, assisted by renowned Llano geologist, Dr. Virgil Barnes, investigated the Ordovician Ellenberger Group and, to a lesser extent, Cambrian carbonates, around the Llano Uplift of Central Texas for lead-zinc potential. Upon graduation in 1977, Mr. Collier became a full-time employee of HO&M, at which time he moved to Brownwood, Texas. From the field office in Brownwood, HO&M directed an active drilling program resulting from the drill cuttings investigation. Mr. Collier’s duties included project planning, field mapping, site preparation, oversight of multiple drill rigs, geophysical logging of boreholes, and detailed logging of thousands of feet of cores acquired by diamond drilling. Through analysis of the data he produced maps showing carbonate facies, percent limestone/dolomite, collapse structures, and mineral distribution.
In 1978, with gold prices soaring and zinc prices falling, Mr. Collier moved to Denver and began working in the western United States. HO&M had purchased Summa Corporation, the holding company for Howard Hughes’ mining properties. Mr. Collier worked in Nevada evaluating various Summa mining claims, as well as performing reconnaissance for other favorable areas for exploration. Most of his work was in the Goldfield District, where the mineralized veins occur within silicified zones in altered Tertiary volcanics. Projects involved staking claims, basic Brunton and tape mapping of the prospects’ structures and surface geology, subsurface mapping from drilling data and underground mines, and geochemical sampling. Later, Mr. Collier managed an exploration project for potential massive sulfide deposits in the Seven Devils Volcanics of western Idaho. The project consisted of mapping, sampling, and directional drilling in a rugged, mountainous region near Hells Canyon. Evaluation of a molybdenum deposit in Georgia led Mr. Collier back to exploration in the eastern and central U.S. The molybdenum occurs in the Knox Group (Ordovician) and has been classified as a possible Mississippi-Valley Type deposit. Mr. Collier directed drilling that discovered low-grade molybdenum ore within fractures in the Knox. The prospect was later obtained by North American Exploration Inc., who labelled it the “Shiloh Church Prospect” and presented findings at the 112th American Institute of Mining Metallurgical, and Petroleum Engineers in 1983. Mr. Collier headed a meagerly-funded reconnaissance program for lead-zinc potential in the Southeast Missouri Lead Belt that quickly expanded to an aggressive land acquisition and drilling program, testing unexplored areas west and south of the known mineralized trend. He relocated to Missouri and opened a regional office from where, as Senior Exploration Geologist, he managed exploration in the Mid-Continent of the U.S, with a focus on Southeast Missouri. Mr. Collier was responsible for all phases of exploration from budget development to reconnaissance to calculation of reserves. He developed conceptual models, generated new projects for minerals exploration, and accomplished exploration of approved projects utilizing a multi-disciplined approach that included geochemical and geophysical methods. Mapping of facies and lithofacies, as well as petrographic analysis of microfacies, were important components of exploration efforts. He planned and directed intensive drilling programs using mud rotary, air hammer, diamond coring, and reverse circulation equipment. Mr. Collier pursued to completion the acquisition of federal lands for minerals exploration. The application process involved compliance with regulations of the United States Department of the Interior (Bureau of Land Management) and United States Forest Service (USDA). While the typical time for approval could run into several years, HO&M’s permits were approved within a year.
The Southeast Missouri project was eventually scaled back, driven by the predicted end of lead as an additive in gasoline and by Tenneco’s purchase of HO&M. In a review for a potential joint venture partner, Mr. Collier’s project was recognized by an independent outside consultant as being “in the forefront of exploration knowledge in Southeast Missouri.” In 1986, Mr. Collier co-authored a paper entitled “Dolomitized Galena-bearing Bonneterre Formation in Western Shannon County, Missouri.” The paper was presented at the Symposium On The Bonneterre Formation (Cambrian), Southeastern Missouri in Rolla, Missouri.
Professional Participation and Contributions
Mr. Collier has been active in several capacities to represent and advance the profession of geology. He has made presentations at numerous events, including Texas Natural Resource Conservation Commission Options for Texas in 1996 (predecessor Texas Commission on Environmental Quality Environmental Trade Fair) and East Texas Water Conference in 2012. Some of his additional contributions are:
