We show that unconstrained anisotropic 2.5D inversion of Towed Streamer EM data in complex geological settings can produce resistivity models that are consistent with both interpreted log and seismic...

Towed streamer electromagnetic (EM) data over the Mariner oilfield in the UK sector of the North has been inverted using a fast and efficient 3D anisotropic inversion code. The electric field data...

In exploration geophysics, both primaries and multiples can be used for depth imaging. This is feasible after applying wavefield separation to generate up-going and down-going wavefields. The...

The towing depth applicable to dual sensor streamer acquisition has hitherto been limited by operational challenges associated with maintaining the fronts of the streamers at a deeper tow position,...

The case study investigates the applicability of certain processing steps to a simultaneous long offset acquisition configuration using a data set acquired offshore Gabon. This acquisition...

The underexplored offshore deepwater basins of Angola and Namibia hold tremendous potential for hydrocarbons. Recently acquired broadband 2D seismic from the Namibe Basin (offshore Angola) and...

A novel method for integrating Towed Streamer EM and dual-sensor seismic data is introduced. The method is referred to as seismic guided EM inversion, where a sparse-layer depth model defined by...

Swell noise attenuation is the first step in the processing sequence of marine seismic data. Often this filtering requires a good amount of testing to achieve optimal results, particularly when swell...

It is well known that surface-related multiple elimination (SRME) breaks down when applied to shallow water datasets. The prediction is distorted at the reconstruction stage by the NMO stretch of the...

One of the critical components for a successful 4D seismic project is to maximize imaging repeatability between the different seismic vintages in seismic processing by the use of same seismic...
