ROCKY MOUNTAIN
SHALE GAS EVALUATION PROJECT
Unconventional shale gas resource plays have become a key exploration
target for the petroleum industry and investors. This interest derives
mostly from the success of the Barnett Shale, and to a lesser extent, the
Ohio-New Albany Devonian Shales of the eastern US. Although many rock
attributes are of importance in determining what defines commercially
productive shale, the characteristics of its gas generative capacity,
thermal maturity, kerogen type, and its fracturability are of prime
importance in obtaining high gas flow rates. Thus, these plays are being
directed by geochemical assessments of suitable combined source-reservoir
rock systems and completion (engineering) techniques.
This proposal outlines a sampling program that will generate interpreted
data that are critical to making sound economic decisions on leasing, and
the viability of participating in a variety of fractured shale plays
throughout the Rocky Mountains.
Key results to be derived from completion of this study on prospective
shale gas candidates include:
determination of organic richness of shales
determination of present-day and original generation potentials of shales
assessment of organic richness and total generation potentials related to
gas yields
thermal maturity determination from well profiles and shale samples of
interest
kerogen type assessment as it relates to product composition versus maturity
maps of yield and maturity
determination of the presence of catalytically active metals
full mineralogy
SAMPLING PROGRAM
The program in its entirety, for all the basins illustrated on the cover
and in Fig XX, will provide data from over 2000 samples from the source
rock intervals (Fig Y) throughout the Rocky Mountain area. These data will
be supplemented with data collected from public domain sources in order to
give a comprehensive overview of the source generative potential and
mineralogy of each shale.
Samples will be collected from multiple source rock intervals in 7-20
wells per basin. The location of sampled wells will be determined, with
client input, by the overall structure of the basin (depth variations,
fault locations), and what is know of source rock facies distribution(s)
within the basin, including their thickness, variation in heat flow, etc.
Most samples will be collected selectively from well cutting collections
based on whether the collection is of suitable quality, gamma ray
signature, shale color, etc. These will be supplemented with samples from
cores and outcrops that promise to fill in sample coverage gaps across a
basin.
ANALYSES
SOURCE ROCK ANALYSES
Using the Barnett Shale model as one key to evaluating capacity of shale
resources to produce commercial quantities of gas, an analytical program
specifically directed at assessing prospective areas for shale gas
production has been established to determine geochemical attributes. These
include:
total organic carbon which is directly proportional to potential gas yields
kerogen type, which impacts product composition
organic matter transformation ratio, which assesses the extent of kerogen
conversion
thermal maturity, which helps determine which source rocks are in the gas
window
product composition at given maturity levels, which help assess producibility
These characteristics can be derived from geochemical analyses such as TOC
(total organic carbon), Rock-Eval analysis, vitrinite reflectance-thermal
alteration index, visual kerogen assessment, and light hydrocarbon (LH)
whole rock extract fingerprinting.
It has also been shown that source rocks can be catalytically active with
enhanced capacity to convert higher molecular hydrocarbons to methane at
various levels of thermal maturity (Mango, 1997; Mango, 2005; Fuhrman et
al., 2003). These catalysts may range from carbon char, pyrite, and
transition metals. The presence of zero valence transition metals such as
nickel is to be determined by unique and exclusive techniques at Humble
and Petroleum Habitats.
The resulting geochemical data can be used to construct maps of the best
prospective areas for producible shale gas.
MINERALOGICAL ANALYSES
Mineral analyses will be performed in order to gain insights into how
susceptible shale is to fracturing, as well as its sensitivity to drilling
and completion fluids. The analyses also serve as additional indicators of
thermal maturation.
The mineral analyses will include basic and more detailed clay
mineralogical analyses along with important minerals, such as calcite,
dolomite, chart and quartz that contribute to the ability to fracture a
shale gas horizon and affect fracture gradients. The detailed clay mineral
analyses (smectite/illite transformation profiles, chlorite, illite,
kaolinite speciation) will substantially aid in our understanding of the
thermal maturation assessments performed, and the efficiency of gas
generation from the source rock systems sampled.
METAL ANALYSES
Metals are included in this analysis because they may, in conjunction with
the source rock and clay mineral analyses may be important because of
economic considerations (i.e., sulfur) as well as possible catalytic
interactions with the source-reservoir system. The following metals are to
be included in the analysis:
Nickel
Vanadium
Cobalt
Iron
Chromium
Iron Oxides
Sulfur
and others
INTEGRATION WITH OTHER DATA
Data acquired in the context of this evaluation will be viewed within the
regional geological framework of each basin. Such factors as the overall
structure of the basin, location of significant faults, previously
published source rock facies distribution maps, including thickness
variations, heat flow distribution, amount of sedimentary unroofing, etc.,
within a particular basin, will be taken into account in the final
analysis.
The data generated will also be supplemented with source rock data from
other publications and public domain files in order to define more
precisely the lateral confines of fractured shale resource plays
throughout the Rockies.
