Seismic Studio™ is the premier statics solution for challenging land and marine data sets where shallow subsurface velocity and geometry problems degrade the quality of seismic data. In addition, geometry problems can be identified and corrected.
2D and 3D Geometry Corrections & First Break Picking
Robust seismic processing requires accurate geometries, yet typical land and marine OBC surveys often have errors in source and/or receiver locations that can significantly degrade the integrity of the seismic data and later processing workflows. Seismic Studio interactively determines seismic geometry errors and allows the user to correct them with ease.
Interconnected windows allow the user to pick first breaks simultaneously in several sort planes. Automatic picking and guided picking speed up the process, as well as pick prediction based on analysis of sparsely picking every "Nth" source gather.
Seismic Studio provides numerous diagnostic displays for the analysis and creation of the near surface model and computation of refraction statics.
CRYSTAL™ enhances collaboration and provides a suite of integrated tools that Subsurface Geo-Engineering teams need to manage their assets most effectively. This 64-bit Windows solution provides – in a single, seamless environment – an integrated suite of tools to help you accurately plan, develop, and optimize your fields. Its core functionality is based on modules that generate high-resolution geologic models constrained by seismic and well data.
Real-time completions data and microseismic events can also be visualized and interpreted in tandem with the geologic models, well geometries, and field-scale reservoir property predictions.
More than 70% of the world's known hydrocarbon reservoirs contain natural fracture systems, and oil companies around the world are controlling the high capital costs of drilling and completions optimization by using the Continuous Fracture Modeling (CFM™) workflow from SIGMA? to build predictive models of their reservoirs.
A key part of the integrated CRYSTAL workflow, CFM can be used to compute reservoir sweet spots, as well as predict user-defined properties across the entire geomodel. CFM leverages an advanced, proprietary neural network to find and rank correlations that exist between large volumes of well data, production data, and seismic attributes. The neural network is first trained on a subset of available wells (e.g., using "fracture indicator" logs from FMI, etc.), and then validated by testing its predictions on a separate subset of wells.
The sweet-spot mapping capabilities in CRYSTAL augment the base toolkit of attributes with maps of Young's Modulus, Poisson's Ratio, brittleness, and other key properties that impact stimulation and production. Around the world, SIGMA? has used CFM predictions to enable Subsurface GeoEngineering teams to perform field-level planning and optimization - all in the spirit of determining "Where to Drill", "Where to Frac", "How to Frac", and "Where to Invest".
Sweet-Spot Mapping can also be used in combination with the High-Resolution Imaging and Inversion package to generate detailed fracture density maps around the wellbore. In addition, CRYSTAL 4.0 can generate Discrete-Fracture Networks from CFM results. These fractures can be exported as part of the geo-cellular grid for importing into commercial reservoir simulators, such as Eclipse® and CMGTM, allowing users to forecast well- and field-scale production.
Reservoir geophysics today gives drilling engineers more thorough "road maps" of the subsurface to develop and carry out the best well planning with the lowest risk. In addition, the logging while drilling tools give an updated the earth model.
SIGMA? incorporates a workflow that uses proprietary technologies to develop an industry-leading interpretation of 3D seismic data to give you an unparalleled reservoir description so you can drill with confidence. Our reservoir geophysics solution toolkit includes:
Earth Imaging & Velocity Modeling
Details make the difference, and understanding your reservoir begins with accurate 3D imaging to define essential structure and stratigraphic information in the subsurface. SIGMA? is a leading provider of Depth Imaging software and services to the oil and gas industry. With our advanced imaging technology, we help oil and gas companies visualize accurately 3D earth structures and reduce drilling risks associated with oil and gas exploration. Oil companies lower the cost of production, provide faster delivery of oil and gas to the marketplace, and tap oil and gas from ever more challenging plays.
