Description Based on the integrated sensitivity method, we introduce the concept of controlled sensitivity, which enables the sensitivity of a geophysical survey to be focused on a specific target area of sea bottom formation. In particular, we find the optimal parameters of the data weighing, which make it possible to increase the sensitivity of the survey within a specific area, where a potential geological target (e.g., a hydrocarbon reservoir) may be located. We demonstrate this approach with a numerical study of the sensitivity of the marine controlled-source electromagnetic (MCSEM) surveys, developing a numerical method and computer codes for constructing one-dimensional and twodimensional controlled sensitivity for given a priori sensitivity models. This method represents an important technique to increase the resolution of MCSEM data with respect to a specific target area.
