Career Summary
An accomplished Senior Geophysicist with extensive experience in
acquisition, processing, interpretation and reservoir characterization.
Experience ranges from R&D through Seismic Data Processing to Prospect
Generation, Operations (drilling well decision making) and to Field
(Prospect) Development and Study.
Experienced in all Gulf of Mexico plays including deep water and Sub Salt.
Onshore experience in the Miocene, Wilcox, Smackover and Cotton Valley
plays. Caused the first shelf subsalt objective to be drilled in VM 356 by
depth migrating TOS and BOS via ray traced map migration using the
Sattleger ISPOO3 software.
Foreign experience includes field studies on two Miocene fields in Trinidad
Off-Shore, mapping the Bangladesh portion of the Bay of Bengal, and the
study of four large fields in the onshore Sichuan Basin of China.

2. Domestic experience includes a South Louisiana Zone One exploration
program in which I was solely responsible for acquisition design and
implementation, processing and interpretation. A successful well was drilled
as a result.
From 1963 to 1965 I was responsible for data processing on several models
of analog computer using both AM and FM field and rerecording tapes. The Sources
were both dynamite and Vibroseis. This required graphical diagramming of the
source, receiver and depth point location of every trace and the subsequent
design of a manual sorting process that used an analog “patch panel”. Static
corrections were manually computed and Normal Moveout was manually
determined by manually picking the reflection hyperbolas of the major reflections,
and building a plastic “cam” which translated the NMO into an time varying
electric current which moved the pickup head on the tape to provide a variable
time delay thereby correcting the NMO on a trace by trace basis. The traces
were plotted on photographic paper through a 1/96 inch slot producing a gather
that simulated a stacked trace. These sections were passed to the interpreter.
In 1966, I mapped several 1 inch to 4000 foot quadrangles in the Frio Trend
on unmigrated, transcorded single fold 2d data along and across the Mexican
border as a part of a very large data exchange with PEMEX. The maps were
posted and hand contoured on linen.
In 1967 I was transferred to the AMOCO General Office in Tulsa, OK to participate in
the design and implementation of the first corporate digital processing system, PESOS.
This was a database driven system and was eventually copied by commercial companies.
I was responsible for, Velocity and NMO, and Statics and later for amplitude fidelity in
all programs.
From 1970-1982, I was a Senior Research Scientist, developing and testing seismic data
processing programs for implementation into the corporate processing system. I
developed, automated Velocity Analysis, Automatic Reflection Differential Picking and
Automated trim Static Computation, Amplitude compensation for Divergence,
transmission and reflection losses as a function of offset and time, a non-linear, iterative
de-reverberation technique that made no wavelet assumptions, and a method of
attenuation of deep water hard water-bottom multiples using pattern recognition and
subtraction.
From 1982 1988, I supervised a large group of neo Geophysicists and professional
assistants in processing huge quantities of marine seismic data both newly acquired and
reprocessed from archival data. This included the infamous Gulf-wide sale. My
responsibilities included the teaching of the new hires in the fundamentals of Petroleum
Geophysics, Data Processing, Interpretation and developing their work, data processing,
mapping, and presentation skills.

3. In 1989-1992, I supervised a large group of Earth Scientists who digitally
mapped the entire offshore GOM as a part of a regional project effort. The
resulting regional were among the first large scale digitally produced maps,
both structure and isochronal, at AMOCO. This regional project group also
produced technical projects. One successful project involved incorporating
the 100,000’s of stacking velocity surveys and the 100’s of check shot
surveys into a GOM wide average velocity model for the use of our
interpreters for time and depth conversion. Stacking velocities were
statistically calibrated to check shot velocities which effectively removed the
primary effects of Anisotropy. Another large successful regional project
involved the use of 1000 or more detailed Petro physical analyses to make
trend maps of Petro physical properties by formation.
In 1992 I joined the New Orleans Offshore Business Unit as an Operations
Geophysicist. During the next two years, I was involved in the targeting and
following of several wells in the High Island Hyalina Baltica trend mapped and
picked locations for wells drilled from the “F Platform” in the HI A572 complex
and was then assigned to the MA 622 complex. Both were large, active fields
with active drilling programs and exceptional velocity problems. All but one
“F” platform” well were economic successes. One well set the record (for that time)
for contiguous oil pay (300+ feet) and Open Hole Potential of 10,000+ BBLOPD. I
also laid out a high resolution 3D survey on AMOCO’s largest offshore GOM
property in Matagorda Island and participated in the quality control until I retired
from AMOCO in 1994.
In 1994-1996, coming out of retirement I was contracted by ENRON for 2
field studies in Trinidad, a large mapping project from paper records in the
shallow waters of Bangladesh, and a year-long study of a set of 4 fields in the
Sichuan basin of China. As a part of this project, as the Geophysicist for
ENRON in China, I was given tours of the facilities of the Sichuan section of
CNOC, and several small private companies, and presented the Geophysical
analysis of our plan to develop the 4 Sichuan Basin Fields to the top
Management of CNOC.
In 2004- 2009, I was contracted by Lafourche Realty, a large landowner in
SE LA, to complete field studies of four Miocene fields using 50 sq. miles of
proprietary 3D. I developed more than 40 drillable prospects.

4. Experienced 2-D and 3-D SMT KINGDOM and LandMark mapper. Also
familiar with SURFER mapping and Kriging. Have extensive EarthPak
experience with both digital and raster logs. Have correlated thousands of
logs and used Paleo Control where available. Made hundreds of Geologic
cross sections with annotations of Geology (cores, perfs,etc.),
Production(monthly, cums, tests, etc.), and Paleo Environments.
Extensive experience in generating synthetics and tying Geology to seismic;
time and phase balancing of 2D and 3D seismic grids, modeling seismic
responses and calibrating seismic attributes to lithology and production.
Experienced with impedance inversion and AVO inversion.
Experienced in reservoir productivity prediction, risk evaluation and estimation
of risked return on investment. Developed MS ACCESS software for purpose
of documenting prospects with graphic displays, and computations of net and
gross risked and un-risked reserves and cash flows.
Current in technology: I am competent in the use and quality control of
Time to Depth Conversion, AVO (direct hydrocarbon detection), Migration
before and after Stack ( Subsurface Imaging), Reservoir Characterization,
Complex Seismic Attributes and their application to Reservoir
Characterization.
Expert in Velocity and Time to Depth Conversion Technology. Two Papers
published. Have taught classes on time to depth conversion for AMOCO and
for SIPES.
Experienced in R&D and Seismic data processing and quality control.
Experienced Corporate Trainer. Taught in-house courses and acted as a
mentor for new hires. Experienced user of Wolfram’s MATHEMATICA which I
use for derivations of useful formulas and for fancy Graphic Displays for
teaching
