Development & Calibration of New 3-D Vector VSP Imaging Technology, Vinton
This project was selected in response to DOE's Oil Exploration and Production
solicitation DE-PS26-01NT41048 (focus area: Critical Upstream Advanced Diagnostics
and Imaging Technology). The goal of the solicitation is to continue critical
upstream cross-cutting, interdisciplinary research for the development of advanced
and innovative technologies for imaging and quantifying reservoir rock and fluid
properties for improved oil recovery.
This research addresses both improvement in processing of subsurface data and
development of technology to increase resolution of reservoir compartmentalization,
reservoir geometries, and prediction of fluids. Specifically, researchers aim
to extract information that will aid in predicting hydrocarbons, improve the
velocity/depth model, and improve subsurface resolution using a unique 3-D vector
vertical seismic profile (VSP) collected in conjunction with 3-D surface data
over a 100-year-old field associated with the Vinton, LA, Salt Dome.

The project achieved its goals by adapting new technology developed for vector
ocean-bottom-cable seismic analysis to the vector VSP geometry. Researchers
calibrated these new algorithms through 2-D numerical elastic models and a 3-D
elastic physical model. They further calibrated this new technology to Output
Exploration LLC's (OPEX) Vinton Dome property, using two recently acquired,
permanently installed 3-D vector VSP data sets against extensive well control,
check shots, and production data. Finally, researchers will test the vector
VSP predictions with OPEX's drillbit.
There is potential for a significant scientific breakthrough that will allow
domestic producers to more accurately locate, inventory, and produce remaining
hydrocarbon resources. This new technology will have direct application for
identification of reservoir compartmentalization in mature domestic fields.
For Texas onshore salt-dome related fields alone, this potentially affects mature
and super-mature fields that have a cumulative production 5.3 billion barrels
Vinton Dome is of one of OPEX's prime properties, with plans for 2001 that include
more than 10 new wells and a concomitant investment in complete suites of well
logs. OPEX's preliminary results from combining standard 3-D seismic and downhole
VSP data show significant increase in seismic information content and potential
for greatly improved reservoir imaging and amplitude-vs.-offset analysis of
rock and fluid properties. The results of the proposed University of Houston-OPEX
project will form part of OPEX's Vinton Dome reservoir characterization and
management program, thereby becoming a real-time research effort to enhance
domestic oil and gas production.
Tasks performed include:
- Numerical and physical modeling-used OPEX well control and 3-D surface seismic
to build multiple 2-D numerical and one 3-D 1:10,000 scale physical model
to simulate vector VSP data with a known solution.
- Algorithm development-developed prototype vector processing, velocity analysis,
and imaging algorithms.
- Algorithm calibration-calibrated vector VSP algorithms with the aid of the
numerical and physical model data sets researchers developed.
- Algorithm application to Vinton Dome-applied vector VSP algorithms using
OPEX's two 3-D vector VSP data sets.
- Data integration-integrated 3-D vector VSP images with existing 3-D surface
seismic image. Evaluated improvements in illumination, resolution, and hydrocarbon
Project is complete.
