Abstract
Summary
Multicomponent technology is likely to become the standard in future towed streamer surveys. Among reasons to acquire multicomponent data is to increase efficiency (deep tow) in acquisition, increase resolution (deghost) of pressure data, interpolate to a fine grid (using crossline directional measurements). One of the challenges of working with towed streamer multicomponent data is the fact that the measured low frequencies in the directional components are rather noisy mostly due to practical aspects/limitations. We present a formalism based on Green’s theorem that provides tools to reconstruct, redatum, and/or denoise these components, and/or for deghosting.
