Formal Education
Jay
R. Scheevel
holds a B.S. in Geology with distinction (1979) University
of Illinois, and an M.S. in
Geology
(1981) Texas A&M University,
Center for Tectonophysics.
General Work History and Focus
Jay formed Scheevel Geo
Technologies
(SGT), a Limited Liability Company in June of 2002.
He is both President and Principal Consultant for SGT which provides advanced
geological and geophysical consultation to the Oil and Gas Industry. SGT
specializes geological/geophysical aspects of reservoir
evaluation/exploitation, equity determination, well planning/execution and
advanced 3D reservoir-modeling.
Recent projects include
use of statistical calibration techniques resulting in dramatic improvement
of the resolution of 3D seismic data and direct estimation of reservoir
petrophysical properties from 3D amplitude data. These techniques are based on advancements
in of technology published in 2001 (Scheevel
and Payrazyan, 2001). Examples of applications to Rocky Mountain Cretaceous
tight gas sands is demonstrated for high-resolution categorical analysis in a
promotional pdf document and for direct
property estimation in a second SGT promotional
pd document.
Other recent projects
include the mechanical analysis of natural fracture genesis in the Mesaverde
formation of the Rocky Mountains. The
project included an elastic analysis of the conditions for fracturing under
abnormally high pore pressures and mechanisms for gas migration in extremely
tight, but fractured host rocks. The results were presented in the 2005
Hedberg conference on tight gas sands in Vail, Colorado and are currently in press.
Prior to forming SGT,
Jay held the position of Geological Consultant for Chevron Overseas
Petroleum.
Joining Chevron in 1981, he has held positions in all areas of Exploration
and Development Geology and Geophysics, and has been heavily involved in
Reservoir Management.
His career has been roughly split between Exploration and Production
assignments with an additional assignment in research and development. His
most recent work was in operations as the Special Projects Geologist in Cabinda, Angola,
West Africa.
His work introduced
advanced reservoir modeling,
reservoir-management
and well-design/geosteering
techniques to ChevronTexaco’s 400+ MBOPD operation in Cabinda. The advanced methods used in Cabinda were
leveraged by introducing the use of computer-based 3D modeling (GoCad) techniques, some of which were
developed and deployed in Cabinda for the first time worldwide (Sullivan and Scheevel 2002).
Prior to joining
ChevronTexaco’s Cabinda operation, Jay
was assigned to Chevron Petroleum Technology Company (CPTC) LaHabra Research
Laboratory. He was involved in active research/development and worldwide
deployment of Chevron’s proprietary version of the GoCad 3D earth-modeling package.
He was involved in the development of advanced geophysical interpretation,
and helped develop an advanced method of geophysically-constrained reservoir
modeling using principal component analysis (Scheevel and Payrazyan, 2001).
These efforts also included the development of reservoir scale (ultra-high
resolution) 3D seismic interpretation, rigorous time-to-depth conversion of
seismic data, and geostatistical methods applied to reservoir
characterization. Jay has also contributed directly to the development of a
variety of other geostatistical techniques in the GoCad software’s G2
geostatistical module.
While serving in the Geostatistics
Team at CPTC,
he made contributions in the areas of extrapolation
of complex surfaces in 3D models, structural characterization in 3D
using dipmeter data and application of neural networks to a large variety of
reservoir description problems. Jay has also participated in the evaluation
of neural networks in various production optimization methods, and has
coauthored a paper on the subject (Stoessel
et al, 1998).
Jay is the author of
original PC software for automatic time-to-depth modeling using advanced neural network techniques.
This software was used extensively at Chevron for many years. Jay has
successfully negotiated for release of this and other neural network software
that he authored. He is currently preparing this package for commercial
release in the near future.
Jay’s continuous
15 year involvement in production
and exploration work on West Africa’s Lower Congo Basin combined
with regional tectonic analysis based on seismic interpretation of Congolese,
Angolan and Namibian seismic and gravity data resulted in presented and
published syntheses on the tectonic development of that region (Scheevel and Dale, 1993, Scheevel et al, 1996 & Braccini et al, 1997). Jay has also worked
and published on Laramide-aged tectonics of the Rocky Mountain Foreland (Scheevel, 1983).
Throughout his career,
Jay has served principally as a line-professional in geology and/or
geophysics assignments in Chevron’s Operating Companies. He has made it his role to be
involved in the application and testing of advanced technologies under
practical working conditions. Jay has a critical eye for what technologies
work and which ones do not, as well as how to evaluate new technologies
rapidly and effectively in the production environment. He has worked
extensively in operations settings
throughout the world and has proposed and drilled successful exploration and
development plays in the U. S. Rocky Mountains, West Texas and West Africa. Jay has also performed
more limited work as a consultant on fields in the North Sea, Australia,
Papua New Guinea and Venezuela.
He has taught multiple courses worldwide on subjects including
reservoir-modeling, geostatistics, geophysical interpretation,
rock-mechanics, and structural analysis.
During all of his
assignments, Jay has worked extensively with reservoir engineers on equity,
depletion-planning, and reservoir-management. He understands engineering
concepts and knows the downhole environment, operational and drilling
constraints. This experience allows Jay to integrate the geosciences with the engineering disciplines
in a very practical and effective way.
Jay is a member of the AAPG (American
Association of Petroleum Geologists), SPE
(Society of Petroleum Engineers), AGU
(American Geophysical Union), GSA
(Geological Society of America), Sigma Xi (Scientific
Research Society), and numerous regional geology associations. He is a
Registered Professional Geologist in the states of California (PG5663) and Wyoming (PG-1042).
