Permanent reservoir monitoring (PRM) using seabed arrays of seismic sensors is becoming a well recognised tool for optimizing production and increasing reserves at lower cost and risk through...
A 3D inversion based Least-Squares Reverse Time Migration (LSRTM) technique was developed. The algorithm uses the RTM as the forward modeling and inversion engine to minimize the amplitude...
The technology of using Tilted Transverse Isotropic Reverse Time Migration (TTI RTM) for subsalt velocity model building has been playing an important role in the seismic industry. Since TTI RTM is a...
Seismic curvature attribute analysis forms an integral part of most interpretation projects as they yield useful information that adds value for the interpreters. Being a popular tool, curvature...
In this abstract, we describe how to improve time domain full waveform inversion using source wavelet convolution, windowed back propagation and source side illumination. Instead of estimating the...
We present an imaging methodology that resulted in significant enhancements in defining the subsurface geology in a survey in the Appalachian Foothills. The key technologies used were (a) high...
The data driven 3D true azimuth Common Focusing Point (CFP) data regularization technique is a multi-dimensional data regularization tool. It can be used as a general tool to merge multiple surveys...
We propose a time-domain approach to transform a gather of pre-stack seismic data into an ensemble of highlyresolved traces in the transformed domain. Using a range of various velocity functions in a...
Extensive sequences of flood basalts dominate the northwest European Atlantic margin. The basalt flows absorb and scatter the higher frequencies present in any source wavelet through intrinsic and...
Shot based pre-stack depth migrations such as RTM are used to generate a partial image volume for each input shot gather. The conventional migrated image formed by summing together these partial...
