Humble Geochemical Services is pleased to offer one hour seminars on various topics and applications in organic geochemistry. If you would be interested in such a presentation, please contact to arrange a time. We have presented these topics either during regular working hours or as lunch-time presentations that provide a break from day-to-day activities with the opportunity for interaction between speaker and audience as well as among the audience themselves.
Topics
Planning a Geochemical Program
This discussion focuses on defining objectives for a particular
geochemical study and the analyses and samples necessary to meet these
objectives. A properly designed geochemical program is absolutely
necessary to achieve maximum benefit from the program and to insure that
the correct samples are gathered, that they are gathered properly, and
that the analytical program is properly designed for the objectives of
the study. Objective evaluation worksheets are provided. Budgeting is
also included for both regional and well programs.
Kinetics for Geologists (or geochemists)
Befuddled by this chemical terminology and what it means in the process
and timing of the generation of oil? This 1 hour discussion provides a
simple explanation of the complex process of organic matter decomposition
into oil and how it affects the timing of oil generation and expulsion.
A “Velcro quilt” analogy is used to explain the process,
structure and composition, and kinetic parameters in terms familiar to
everyone. Examples of typical source rocks from around the world are
also described and compared.
Finding Overlooked Payzones
One of my first applications in organic geochemistry was geochemically
logging a well to identify payzones in the Anadarko Basin (Jarvie and
Baker, 1984). The interesting aspect of this paper was not the fact the
we correctly identified the productive interval discovered but the fact
that one potentially productive zone was overlooked. Since that time we
have used organic geochemistry to identify hard-to-find payzones and
predict oil quality prior to testing.
Where these techniques work best and how to incorporate data into your
well evaluation process are discussed in this talk. Where does it work
best? Fractured shale reservoirs, low resistivity sands, stacked sands,
wells drilled with oil-based mud, wells drilled through fresh water.
This technique has a straight-forward payback - oil/condensate in active
or previously drilled wells.
Exploration Geochemistry
This is a general talk on aspects of geochemistry used to identify
petroleum source rocks, their petroleum potential, products likely to
be generated, thermal maturity, timing of generation, oil-to-source
rock correlation, and oil typing and correlation. This talk focuses
on recent advances in techniques and application of organic
geochemistry for unraveling source potential and expulsion temperatures.
Reservoir Compartmentalization
(for development geologists and engineers)
Looking to shut-in a well for pressure testing to evaluate reservoir
continuity? This is an outstanding technique for evaluating connectivity
but what about lost production and what if the well doesn't come back on
line? Reservoir Oil Fingerprinting™ (ROF) is a technique that
utilizes a graphical and statistical comparison of oil fingerprints to
assess continuity. Oil samples from various wells and horizons are
“fingerprinted” revealing any compositional hetergeneity that
results when reservoirs are not connected. Does it work? Various examples
both published and unpublished (but nonproprietary) examples are
presented demonstrating the efficacy of this technique.
Interpretive Geochemistry
This is a sequential series of approximately 1 hour seminars providing
basic and detailed assessment of geochemical data to really understand
these data. The seminar series proceeds from basic, screening analysis
to detailed basin wide evaluations. Topics are presented in the
following sequence (although depending of the audience and level of
understanding any topic may be presented in or out of sequence):
Re-evaluation of Petroleum Systems of
the Williston Basin
This is a summary presentation from four separate talks given on the
petroleum systems of the Williston Basin. This talk focuses on
previously unidentified effective source rocks in the basin, their rates
of decomposition into oil and gas, and an evaluation of oil types across
the basin. Oils from every producing horizon in the Williston Basin are
discussed.
Rates and Products formed from oxygen and
sulfur rich kerogens of the Monterey Formation, Santa Maria Basin,
California
This talk focuses on the chemical characteristics of the Monterey
Formation that result in quite different rates of kerogen decomposition
among various organic facies within the Monterey Formation. Phosphatic
Monterey Formation rocks having high oxygen and sulfur contents undergo
transformation at much lower thermal thresholds than strictly sulfur
rich Monterey Formation kerogens. Comparison to other Type II source
rocks is presented.
