EM comes of age

摘要

Electromagnetics (EM) continues to be the new darling of the exploration industry. By taking resistivity measurements of deep-lying sediments, EM technology can often provide an indication of the presence of hydrocarbons, something that the best seismic data can rarely do. The recent commercial availability of this technique has spawned several companies that specialize in the technology, and the people who work for these companies have been quick to emphasize the fact that EM is not intended to replace seismic but rather act as a complementary technology. To that end company researchers have been working on software products that help explorationists integrate seismic data with EM data to get a better picture of the reservoir.
