Abstract

During the past decade long-offset transient electromagnetics (LOTEM) was applied to many exploration problems in Africa, Australia, China, Europe, India and the USA . Initially, the technique was applied in areas where Bood seismic data was difficult to obtain. With the experience of ongoing surveys and an improvement in instrumeritation, the main application which is emerging is the combination with seismics to map porosities in carbonate reservoirs. The major problems overcome along the way included acquisition difficulties (strong cultural noise levels, not enough data), data processing difficulties (low signal-to-noise ratios), and interpretation limitations (restricted 3-D modeling capabilities). LOTEM is now a vérsatile and reliable exploration tool .
