Fusion offers a full suite of seismic analysis techniques to our customers. The goal of seismic analysis is to extract additional information from seismic data beyond the conventional approaches to structural mapping and stratigraphic interpretation. Seismic analysis provides powerful additional information that can be used to lower your risk in exploration, and to quantify your reserves in production. Fusion's seismic analysis offerings include:
 

AVO for Fluids & Lithology

 

Fusion´s approach to AV0 analysis is aimed at understanding the full range of physical properties of the rocks and fluids that may be present in the subsurface. Rather than starting with an observed AVO anomaly and generating a discrete earth model that matches and using this to evaluate risk, we start by looking at the geology and the range of possible rock properties. Forward modeling of these physical properties produces a range of possible seismic amplitude responses. Only by comparing the observed anomaly with these expectations built from our geological knowledge can the observed amplitude anomaly be correctly evaluated.

To risk a prospect we must know how closely the AVO matches the expected response for oil or gas AND how closely it matches brine or other lithologic responses that could mislead the interpreter. Fusion offers the full range of AVO and other offset-dependent analysis methods that are designed to accurately predict the rock and fluid properties in the subsurface. These methods are offered as stand-alone products or as part of integrated studies involving multiple data types.

Neural Network Inversion

 

The use of artificial intelligence algorithms to solve geophysical problems is an exciting recent development in the field. Neural network inversion (NNI) uses the information from multiple wells and seismic data to train the Neural Network to predict properties away from the well control. Fusion offers a range of NNI methods using resistivity and acoustic methods, and we apply these methods to some of the industry´s most difficult problems.

Spectral Decomposition

 

Fusion has developed a unique approach to spectral decomposition that has proven itself to be superior to all other available techniques including Fast Fourier Transforms (FFT), Discrete Fourier Transforms (DFT) and Maximum Entropy Method (MEM) methods. Fusion´s proprietary method is an instantaneous spectral attribute which was orignally trademarked under the name InSpect™. Fusion developed InSpect™ under a research grant from the Gas Technology Institute (GTI), and offers this technology under an exclusive license from GTI. Additional research and development led to a second major breakthrough, resulting in the release of an even better algorithm called ExSpect™. The ExSpect™ algorithm is a significant improvement over all previous methods, and is now being offered both as a service and as a supplemental module to the SpecMAN™ spectral analysis toolkit.

FluidPRO™ Fluid Properties Inversion

 

Fusion has developed a proprietary technique for performing fluid properties inversion. This process has been trademarked under the name FluidPRO™. Fusion offers this technique as a service to our clients who are interested in understanding the variations in fluid properties in their reservoir as a means to better predict reservoir performance and to plan for field development. FluidPRO™ requires two primary inputs including (1) seismic attributes extracted on the horizon or interval of interest and (2) rock physics calibration from wells in the area. The details of these data requirements are available upon request from Fusion. The FluidPRO™ process provides several outputs including (1) maps of the estimated fluid properties for a given horizon or interval, (2) a map of the cumulative probability distribution function for that horizon or interval, (3) quality control maps for each estimated fluid property map, (4) digital data for each of the products above, and (5) a final report with analysis and interpretation. For additional details on data requirements, pricing and deliverables, please contact Fusion and we will be happy to provide a detailed seminar on this exciting new product.

 










 
 

ThinMAN™ Broadband Spectral Inversion

 

Fusion Petroleum Technologies Inc. has developed a revolutionary broadband spectral inversion technique that produces ultra-high-resolution seismic data that enhances mapping and further analysis. This new technique, called ThinMAN™, removes the deleterious effects of the seismic wavelet that cause degraded resolution. ThinMAN™ can be performed without well calibration, and requires no a priori model, no interpreted horizons, and no assumed reflectivity spectra. ThinMAN™ is now being offered exclusively by Fusion and can be used in a broad range of applications. For a quote on the application of ThinMAN™ to your exploration and production problems, please call us at our offices shown below.





ThinMAN™ provides superior resolution over conventional inversion methods
that can be applied to a broad range of geophysical problems.

Note the local variations in the thickness of the Barnett shale on the ThinMAN™ section that are not obvious in the original section.

 

LithPRO™ Multi-Attribute Inversion

 

Fusion Petroleum Technologies Inc. has developed an advanced statistical attribute inversion technology that provides robust statistical attribute analysis in complex geologic settings that can be used to dramatically improve the results of reservoir characterization and prediction studies. The method, called LithPRO™ is designed to handle a wide range of attributes including spectral attributes generated from Fusion's proprietary InSpect™ spectral decomposition algorithm. LithPRO™ allows the user to apply intelligent design concepts to the use seismic attributes to dramatically enhance reservoir characterization studies.

 



LithPRO™ provides superior resolution of reservoir and fluid properties that can greatly enhance
reservoir characterization studies and drilling results in difficult geologic settings.

 

Seismic Attribute Analysis

 

Fusion has considerable experience in attribute analysis and geostatistics. We use attributes from the seismic data along with well control to map the physical properties measured from the well over the area covered by the seismic data. The first step is to identify which seismic attributes, individually or in combination, provide the optimal correlation with the rock properties. We have successfully applied this technology in exploration and field development scenarios. Most seismic attributes are, however, bulk averages over as much as several hundred feet of rock, and the predicted maps are also restricted by this resolution limit. We can offer geostatistical predictions with significantly higher vertical resolution by including a layered template built from well logs or external geological models into the analysis. This approach produces a 3D volume of the target reservoir that can be used for detailed reservoir characterization.

HazPROTM Shallow Hazard Analysis

 

Deepwater environments are known for their shallow hazards. Fusion scientists have been in the forefront of recent developments in the field of shallow hazard analysis and particularly in the prediction of shallow water flows (SWF). Fusion applies this experience to perform shallow hazard analysis using our proprietary methods in geopressure prediction, seismic attribute analysis and advanced velocity and tomography analysis. These methods provide robust interpretation for the challenges that our clients face in drilling their most important deepwater prospects, and assure that these very costly exploration wells can be drilled and completed within budget and without major incidents in the shallow section.
