ABSTRACT

We have designed two Previous Hit3-DNext Hit geologic models and simulated realistic Previous Hit3-DNext Hit 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 Previous Hit3-DNext Hit 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 Previous Hit3-DTop datasets is expected to increase for many years.
