Abstract
Method for rapid inversion of data from a controlled-source electromagnetic survey of a subterranean region. Selected () common-receiver or common-source gathers of the data are reformed into composite gathers () by summing their data. Each composite gather is forward modeled (in the inversion process) with multiple active source locations (). Computer time is reduced in proportion to the ratio of the total number of composite gathers to the total number of original common-receiver or common-source gathers. The data may be phase encoded to prevent data cancellation. Methods for mitigating loss of far offset information by data overlap in the summing process are disclosed.
