• Low-frequency seismic deghosting (PDF)
• First application of Green’s theorem-derived source and receiver deghosting on deep-water Gulf of Mexico synthetic (SEAM) and field data (PDF)
• Green’s theorem deghosting algorithms in (k,ω) (E.G., P-Vz deghosting) as a special case of (x,ω) algorithms (based on Green’s theorem) with: (1) significant practical advantage and disadvantages of algorithms in each domain, and (2) a new message, implication and opportunity for marine towed streamer, ocean bottom and on-shore acquisition and applications (PDF)
• A new Green’s theorem deghosting method that simultaneously: (1) avoids a finite-difference approximation for the normal derivative of the pressure and, (2) avoids the need for replacing the normal derivative of pressure with the vertical component of particle velocity, thereby avoiding issues that can arise within each of those two assumptions/approaches: theory and analytic and numeric examples (PDF)
