ABSTRACT
We have designed two 3-D
geologic models and simulated realistic 3-D surveys based on those models.
This has been a collaborative effort of the Society of Exploration Geophysicists
(SEG), the European Association of Exploration Geophysicists, and the United
States Department of Energy National Laboratories. The project is usually
referred to as the SEG/EAEG Modeling, or SEM, project. The two salt and
overthrust 3-D models and the respective synthetic datasets will be made
available to both the oil industry and academia. This SEM project has been
a sizable undertaking, with computational requirements of several million
dollars. By the end of 1995, about 800 gigabytes of data had been generated,
completing Phase A and Phase B of the project. "Classic datasets" containing
subsets of calculations conducted for Phases A and B have been defined.
Any other subsets of data could be extracted from the whole dataset using
a procedure devised at Lawrence Livermore National Laboratory (LLNL). Additional
calculations of about three terabytes, Phase C, will be carried out as
the project is completed around mid-1997. These datasets have already been
used by many for testing and validating processing algorithms and aiding
in survey design. Their use as standard 3-D datasets is expected to increase
for many years. |
