MEMORANDUM
TO: INTERESTED
OIL COMPANIES - Eastern Canada
FROM:
James M. Brooks, Ph.D.
President
RE: 2000
EASTERN CANADA SURFACE GEOCHEMICAL EXPLORATION (SGE) &
HEAT FLOW (HF) CONSORTIUM PROGRAMS
TDI-Brooks
International, Inc. is pleased to offer these 2000 Eastern
Canada SGE and HF Programs following the same design as our
prior worldwide consortium programs in which most E&P
companies have participated. The proposed Eastern Canada SGE
& HF Consortium Programs are scheduled to be acquired
starting in late August 2000. Cost for participation in these
approximately 150 core SGE and 50 probe HF programs are $200,000
and $75,000, respectively. If more than four (4) companies
join the SGE program, the $800,000 program price will be reduced
proportionately. There are three current Subscribers to the
SGE study.
The program
is already committed with three Subscribers. Early subscription
is ONLY open until 15 August 2000. After the early subscription
to the program is closed on 15 August, late subscription will
not be open again until January 1st, 2002.
2000
Eastern Canada SGE Program - The Eastern Canada
SGE program will involve the collection of approximately 150
cores offshore Nova Scotia in open, deep water acreage. The
locations will be provided by the oil company participants
based on regional seismic available for the area. The attached
figure shows a tentative list of locations selected by the
three current Early Participants. Additional participants
will have the option to add additional locations.
The first
goal of this program will be to determine regionally the distribution
of active oil generation and migration to the seafloor on
the Eastern Canada continental margin. The second goal is
to define the distribution of oil families and maturities
in the region based on biological marker and isotope analyses
provided by GeoMark Research.
SGE studies
can be used at two levels. Most previous studies have been
used to define the regional distribution of oil, condensate,
and gas seepage on the continental margin in order to high
grade areas and prospects by defining areas of active oil
migration and charge through routine gas and high molecular
weight hydrocarbon screening methods. Over the last fifteen
years, our programs have had major impact on deep water exploration
worldwide by delineating areas of active oil migration to
the seafloor. This active migration acts to charge accompanying
reservoirs in the same geological system. On a secondary level,
SGE coring studies can be used to define the distribution
of oil families and maturities across a continental margin
since there is often considerable macroseepage of 'live' oil
into seafloor sediments. Satellite studies available from
Nigel Press & Associates (NPA) indicate that areas of
macroseepage of oil to the seasurface exist in regions offshore
Eastern Canada (Eastern Canada, Offshore Seepage Studies from
Satellite Radar; E-Mail: nigel@npagroup.co.uk). Thus, our
SGE study should expect to acquire macroseep samples that
can be analyzed for biological markers and isotopes by GeoMark
Research for correlation with their Eastern Canada oil database.
Program
Team - The program team consists of the extensive
surface geochemical exploration (SGE) experience of TDI-Brooks
and the unparalleled oil expertise and database of GeoMark
Research. The program will follow the same very successful
strategy we used on our previous Gulf of Mexico and west African
consortium programs that nearly thirty (30) international
exploration companies have participated.
Acquisition
& Analysis - The core collections will consist
of our standard 2,000 lb., 20 ft. piston coring with differential
GPS navigation. All samples are processed in a clean laboratory
and immediately frozen on the vessel. A suite of geochemical
analyses (headspace gases, total scanning fluorescence, and
C15+ hydrocarbon using GC-FID) are conducted on three sections
from each core to determine regional seepage and R1 distribution
patterns. The SGE component will be conducted using the same
acquisition and analytical methods of Dr. Brooks' many other
consortium SGE programs worldwide. In order to aid in understanding
the origin and maturity of the seepages, GeoMark Research
will provide detailed geochemical analysis of all core samples
containing macroseepage or significant amounts of microseepage.
Key tricyclic terpane biomarkers are used to distinguish between
source depositional types. These markers are also very resistant
to biodegradation, allowing for correlation between heavily
biodegraded seep oils and nondegraded subsurface oils. Aromatic
biomarkers will also be evaluated. The detailed analytical
program provided by GeoMark for cross-correlation with their
Eastern Canada oil data base is listed below:
o Liquid
Chromatography for % Saturate, % Aromatic Hydrocarbons and
% NSOs
o Stable Carbon Isotope Composition of both Saturate and Aromatic
Hydrocarbons
o Whole Crude Gas Chromatography
o Molecular Sieve Separation of Saturate Hydrocarbons
o Quantitative GC/MS Analysis of Sterane and Terpane Biomarkers
o GC/MS Analysis of Aromatic Hydrocarbons
Multivariate
statistical techniques (cluster and principal component analyses)
using isotopic and key biomarker ratios will aid in grouping
oils/seeps which share a common source. In addition, relative
thermal histories of the oils/seeps will be evaluated based
on certain biomarker distributions. Results will be presented
in hard copy data volumes as well as in digital form (Access
Database and Excel Spreadsheets). A comprehensive hard bound
interpretive volume and color montages will also be provided
to assist in evaluating the exploration significance of the
region.
Heat
Flow Ancillary Program - A regional heat flow program
will be undertaken in collaboration with Dr. Trevor Lewis
using heat flow probes manufactured by the Pacific Geoscience
Center (NRCAN). This program will be similar to other such
studies the team has undertaken in West Africa, the Gulf of
Mexico, the Nile Delta in which many international E&P
companies have participated. Additional details of the heat
flow programs can be provided to those companies unfamiliar
with the technology. The heat flow (HF) program will consist
of about 50 heat flow probe sites directed toward determining
the regional distribution of heat flow along the continental
margin in relatively undisturbed sediment sections. These
heat flow sites are generally independent of the SGE core
sites and away from active conducts for the upward migration
of fluids. Additional experiments may be proposed to examine
variability across (1) domes and diapirs; (2) toe thrusts;
(3) listric normal faults; (4) crustal type changes; and (5)
macroseep core sites. The heat flow sites will be selected
in water depth greater than 500 meters. The final distribution
of sites will be determined by the participating companies.
The program price is $75,000 per participant.
