GeoTech Surveys Limited
Consultants in Geological Research and
Halifax, Nova Scotia
Who Are We?
GeoTech Surveys Limited was incorporated in 1980 as a
private Canadian company based in Nova Scotia. We provide
professional engineering and geological consulting services to
Government agencies and to the petroleum and mining industries
where expertise is required for projects involving geological
information, research, or engineering.
What Do We Do?
We gather information and provide solutions for problems
containing a geological or engineering component. We have
experience in the following activities:
- Route Designs for Natural Gas Pipelines: We can
provide geological information for large engineering projects
requiring an understanding of sub-surface structures, such as for
natural gas pipelines and municipal sewage systems. For example,
we were recently the route designer for the Halifax Lateral
natural gas pipeline. We also participated in the route design
for the pipeline from Goldboro to Cape Breton Island, and for
parts of the Sable Island pipeline to the New England states.
These efforts included a risk assessment for such geological
hazards as fault lines, sink holes and old mine excavations.
- Drill-Stem Pressure and Temperature Profiles: We
have completed numerous temperature and pressure profiles for
wells in the Jeanne d'Arc Basin (Hibernia Field), and the Scotian
Shelf (Venture Field), offshore eastern Canada. The temperatures
were determined using hydrocarbon maturation data based on our
analyses of mascerals selected from well cuttings. The pressures
were calculated from drill-stem tests in conjuction with other
down-hole geophysical data.
- Environmental Impact Statements: We can provide the
geological information required to satisfy the regulatory
requirements for land-based structures, including natural gas
pipelines. We participated in the EIS for the proposed submarine
natural gas pipeline that was to be layed from Sable Island
(Venture Field) to the Nova Scotia mainland in the early
- Site Investigations for Engineering Projects: We
can investigate sites where there are geological hazards, or
where there may be a geological component of a particular
environmental problem. We can also evaluate the appropriateness
of a site selection for industrial purposes or the economic
potential of mining properties, including the smaller
- Geological, Geochemical and Geophysical Surveys: We
have designed, carried out, and interpreted numerous
reconnaissance and detailed mapping programs and data gathering
surveys in support of a wide range of industrial projects.
Airphoto interpretations and sampling programs are
- Drilling Programs: We can design, monitor, and
interpret the results of diamond drilling programs, whether
undertaken for geological exploration or environmental
- Geological Research: We can design, carry out, and
interpret the results of a wide variety of geological research
programs, particularly those which seek out information to an
environmental problem. Recently we developed a technique for
using drill-stem pressure tests to establish deep, subsurface
stress profiles on the Scotian Shelf (Venture Field). This
research resulted in a paper published in CJES, v. 24, 1987. We
have been involved in numerous other research projects including
an analysis of deep-seismic records on the Georges Bank and
- Geological Instruction: We can provide a wide range
of geological instruction to students of adult or younger ages
from elementary to university levels.
- Technical Report Writing: We can write (or
re-write) technical reports with proper grammar, and correct
spelling; design attractive layouts for tables, drawings,
illustrations; and type and print (B&W and/or colour) the reports
on quality bond. We can also write home pages in HTML script for
a web site.
- Data Storage and Retrieval: We can design databases
for digital data storage, the forms for easy data transfer, and
data display reports for showing desired relationships. We can
show graphical and statistical correlations and trends that could
be used for analysis, or for evaluations aimed at solving a
particular technical problem.
What Can We Do For You?
We believe that GeoTech Surveys Limited has the
breadth and depth of experience to provide the expertise to deal
with your needs wherever geological information is required. We
have worked both as a team player and independently.
If you feel your company can benefit from our services, give
us a call to discuss it. We believe we can come to an agreement
where we both benefit, because we believe our rates are
reasonable and competitive.
What Is Our Experience?
GeoTech Surveys Limited has been the investigator for
numerous projects in the mining, petroleum and industrial
sectors. We have undertaken projects across Canada
(Nova Scotia, New Brunswick, Quebec, Ontario, Saskatchewan, and
British Columbia) and the United States (California, Nevada,
Arizona, Idaho, and Oregon).
Warren B. Ervine, Ph.D., P.Eng. is the President of
GeoTech Surveys Limited and its principal investigator.
He is a Geological Engineer with over 47 years experience in the
resource industries and has served numerous corporate, academic
and governmental organizations in Canada and the United
He received his education at the University of Toronto
(B.A.Sc., 1959, M.A.Sc., 1962) and at Stanford University,
California (Ph.D., 1973) and is certified as a Professional
Engineer in Ontario (PEO, 1960) and Nova Scotia (APENS, 1981).
For 8 years prior to forming GeoTech, Dr. Ervine was a Professor
of Geology at universities in the United States and Canada.
