As shale gas resources have emerged as a viable energy source, their characterization has gained significance. The organic content in these shales which.
In a marine environment, topographic features on the sea floor will usually be covered by a thick layer of shale with the rise of sea level, resulting in.
In RTM imaging, double top salt (DTS) is frequently seen but difficult to remove by conventional post-RTM processing. This paper analyzes the DTS.
A frequency domain tomographic inversion was developed to estimate frequency dependent energy attenuation by using prestack depth migration common image.
Two methods have recently been published for carrying out nonstationary spectral broadening (and narrowing) of PS data after it has been mapped into the.
Broadband seismic aims to provide a greater richness of both (a), robust low frequencies – ideal for deep structure imaging, and (b), high frequencies –.
Lifetime stability and reliability of fibre-optic seismic sensors for permanent reservoir monitoring
Permanent reservoir monitoring (PRM) using seabed arrays of seismic sensors is becoming a well recognised tool for optimizing production and increasing.
Least-squares reverse time migration: towards true amplitude imaging and improving the resolution
A 3D inversion based Least-Squares Reverse Time Migration (LSRTM) technique was developed. The algorithm uses the RTM as the forward modeling and.
The technology of using Tilted Transverse Isotropic Reverse Time Migration (TTI RTM) for subsalt velocity model building has been playing an important.
Seismic curvature attribute analysis forms an integral part of most interpretation projects as they yield useful information that adds value for the.
In this abstract, we describe how to improve time domain full waveform inversion using source wavelet convolution, windowed back propagation and source.
We present an imaging methodology that resulted in significant enhancements in defining the subsurface geology in a survey in the Appalachian Foothills..
The data driven 3D true azimuth Common Focusing Point (CFP) data regularization technique is a multi-dimensional data regularization tool. It can be used.
High-resolution Moveout Transform; a robust technique for modeling stackable seismic events
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..
Enhanced imaging using bandwidth extending operators and pre-stack Q-inversion over the northwest European volcanic margin
Extensive sequences of flood basalts dominate the northwest European Atlantic margin. The basalt flows absorb and scatter the higher frequencies present.
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.
Anelastic properties of the earth cause frequency dependent energy attenuation and phase distortion in seismic wave propagation. It is preferred that.
Increased industry exploration interest in the Tarakan Basin, offshore East Kalimantan, Indonesia, has stimulated a need for 3D seismic data that.
5D interpolation methods have proven to be capable of overcoming the constraints of actual data acquisition in a wide range of situations. However, in.
Seismic data acquired with an airgun source and recorded on pressure sensors has been the standard for offshore oil and gas exploration for many years..
