Fusion offers a full suite of seismic inversion and modeling techniques to our customers. The goal of forward and inverse modeling is to use models to extract the information contained in the seismic data and predict from the physical properties what the seismic data should look like. Seismic inversion and modeling provides powerful additional information that can be used to lower your risk in exploration, and to quantify your reserves in production. Fusion's inversion and modeling offerings include: Velocity Analysis & Tomography
Quality velocity information is critical to robust imaging, pressure prediction, AVO analysis and time-to-depth conversion. Fusion has developed a suite of proprietary methods that allow our scientists to determine velocities in a robust and very flexible way. The geophysicist can use a variety of velocity and geologic information separately or in combination to derive velocities. These methods provide a flexible and efficient platform for predicting velocities that can be used to improve the quality of subsequent interpretation and analysis.
Fusion has developed a very robust process for residual velocity analysis which is trademarked under the name REVEL™. The REVEL™ process allows Fusion to perform an initial velocity analysis on a typical spacing of 250 to 500 meters, and then estimate velocities at any finer spacing down to the individual CDP. The REVEL™ process can be used to provide high-resolution velocities for geopressure prediction, AVO analysis and post-stack and pre-stack inversion.
Fusion is also developing advanced tomography and tomographic statics methods that will provide robust velocity analysis in complex geologic settings that can be used to improve the results of seismic imaging and advanced analysis.
This section for Tomography & Tomostatics is under construction.
INVERSION (PRE-STACK & POST-STACK)
There are several flavors of post-stack inversion of seismic data for acoustic impedance that have become standard technology. Post-stack inversion is routinely used by interpreters to better map extent and thickness of reservoirs and to give a qualitative estimate of reservoir quality. Pre-stack inversion enables us to produce two output volumes including AI and poissons ratio. This information can be parameterized in many ways and it is important to match these displays with the specific exploration challenge. If well data are available, the results of the pre-stack inversion can be calibrated with lithology and a cross-plot of lithology and fluid effects can be produced. In some cases, this method can also be applied for high-resolution geopressure prediction.
Fusion offers a wide range of modeling capabilities including conventional stratigraphic and structural modeling, as well as advanced ray-trace modeling techniques, pre-stack wave-equation modeling and borehole seismic modeling. We integrate these modeling techniques with our expertise in rock properties analysis to provide robust well-based predictions and calibrations to seismic data. These predictions and calibrations are an essential component of quantitative seismic studies, and provide the interpreter with ground truth based on well logs that is critical to the evaluation of prospective reservoirs, reservoir delineation, and reservoir simulation.
