High-Resolution Imaging of the Barrolka Dataset Using Diffraction Attributes

We develop a novel method for high-resolution seismic reservoir characterization and to apply it to a dataset acquired by Santos in Barrolka gas field in Australia. Our approach uses diffraction imaging attributes.
   
   
Statoil Lowrank Reverse Time Migration for Subsalt Imaging
   
Statoil Extracting Seismic Events by Predictive Painting and Time-Warping

We are developing a new technology for extracting the geometry of seismic events in migrated images and gathers. The extracted information is useful both for structural seismic interpretation and for seismic velocity estimation.

Our method is based on the technique of predictive painting (Fomel, 2008; 2010) combined with time-warping (Burnett and Fomel, 2009).
   
Kaust Seismic Wave Focusing for Subsurface Imaging and Enhanced Oil Recovery

Our research focuses on the concept of inversion for seismic sources. Two problems sharing similar characteristics are targeted, one with direct application to imaging and a second one with direct application to enhanced oil recovery (EOR). In the imaging application, the sources could be the very scattering caused by the changes in the velocity with position, which, in seismic exploration terms, is represented by a seismic image. The seismic sources we want to invert for could also very well be the actual sources that are used to generate the initial wave field. In both cases, wave propagation is guided by the wave equation, and in both cases the optimization procedure is guided by a fitting or shaping procedure. To implement an accurate inversion for the actual wave generating sources, we must first solve the problem for the secondary (reflection) type of sources. Thus, a reliable seismic wave focusing approach is needed for subsurface imaging. In the EOR application, wave generating sources are sought that would maximize a prescribed outcome at the reservoir. The prescribed outcome, which is user-de fined and reservoir-speci c, aims at increasing the mobility of otherwise entrapped oil, and thus increase production rates or revitalize thought-as-depleted reservoirs. Guided by the maximization goal (e.g. kinetic energy or fluid accelerations), an optimization problem must be solved to arrive at the optimal wave source signal and location to attain the sought outcome. At the heart of these problems is the physics of wave propagation through highly heterogeneous elastic or poro-elastic media, which through various formulations can be geared to serve the prescribed objectives in an optimal way.

Statoil High-resolution Seismic Attributes for Fracture Characterization in Grosmont Formation

We are developing novel technology for high-resolution seismic reservoir characterization with application to high-resolution seismic data acquired by Shell in the heavy-oil Grosmont formation. Our approach uses novel scattering attributes defined by diffraction imaging in the dip-angle domain. Our research team includes geophysicists,
structural geologists, and applied mathematicians, with a strong history of interdisciplinary research collaboration.

Multiazimuth Seismic Diffraction Imaging for Fracture Characterization in Low-Permeability Gas Formations

The goal of this project is to create a new technology for fracture detection using seismic diffraction imaging and to test it against realistic fracture patterns. We also aim to perfect sidewall-core and wireline-based methods and to use them for verifying the new seismic method.

Fast beam migration

We are developing a new technology for wide-azimuth Fast Beam Migration (FBM), a super-efficient seismic imaging algorithm. The faster imaging step allows for more iterations of velocity model building, which enable the processing team to enhance the seismic resolution and imaging of complex geologic structures, and allows for deeper data penetration, steeper dip and sub-salt structure imaging. This advanced imaging methodology will improve success rate and cost effectiveness for new deep-field discoveries, greatly reduce the turnaround time for large surveys, and also have applications in increasing recovery efficiency for the development of existing fields.
   
BGP Enhanced Seismic Imaging of Land Data

We are developing a new technology for seismic imaging of land data. Two major improvements come from enhancing residual static correction through the use of the predictive painting algorithm and enhancing time-to-depth conversion and interval velocity estimation through the use of the time-to-depth conversion algorithm that takes into account lateral velocity variations.

Subsalt Seismic Imaging Using Levelset Methods

We develop new numerical algorithms applicable for seismic imaging in complex subsalt environments, such as the Gulf of Mexico. The first algorithm is fast multiple-arrival traveltime computation in the phase-space domain extended to wave propagation and imaging with the oriented wave equation. The second algorithm is a semi-automatic extraction of salt bodies from seismic images using levelset surface representations.
