Quantitative Amplitude Interpretation toolkit

Quantitative Amplitude Interpretation toolkit

The QAI toolkit gives exploration and production teams the tools they need to find and delineate reservoirs, and to predict rock and fluid properties ahead of the drill bit. As part of the Sharp Reflections platform, the toolkit uses high-performance  computing power (HPC) to deliver an unprecedented degree of interactivity, even on huge multiclient seismic datasets.

With its massive parallel computing engine, the QAI toolkit operates on prestack gathers and partial angle stacks with the power to leverage the full-fidelity amplitude information. Tools for locating and mapping promising seismic amplitude anomalies are combined with forward modeling tools to calibrate prestack amplitudes to well log data. 

Go beyond traditional 3D data to interrogate huge multidimensional data volumes and rapidly screen for DHI and reservoir anomalies.

 

Other highlights include interactive spectral decomposition, versatile crossplotting, and a new multihorizon deck tool that enables automating amplitude analysis for a complete set of horizons.

The software’s high-performance computing power (HPC) and flexible data model allow you to extend interrogations beyond traditional 3D data to huge multidimensional data volumes, including azimuthal, 4D time-lapse and other 5D and 6D datasets.

Benefits

$

Offset-to-angle conversion and amplitude variation with angle (AVA) attributes

$

Multidimensional horizon interpretation and attribute analysis

$

Seismic forward modeling and well tie

$

Advanced cross-plotting

Powered by the QAI toolkit

$

Extend 3D horizons to multidimensional horizons to compute AVA, azimuthal and multivintage or multiversion attributes directly from source gathers.

$

Analyze depositional geometries of reservoir systems on an angle-dependent basis using interactive prestack spectral decomposition.

$

Calibrate results using full prestack well-to-seismic ties and 3D parametric scenario modeling.

$

By calibrating prestack seismic to well data and using interactive attribute cross plots, you can rapidly screen for direct hydrocarbon indicators (DHI), refine interpretation of reservoir surfaces, and develop leads into drill-ready prospects.

Unlocking the value of multi-dimensional data

Sharp Reflections offers a suite of interactive tools on a single platform, coupled with a unique, flexible multidimensional data model powered by HPC. The model collects data into single objects for exceptionally fast multidimensional data computations and interactions.

How does our HPC powered data model help with QAI workflows?

Perform typically repetitive steps in a single execution, on massive datasets, with exceptional speed (reduced from weeks to days or hours). The toolkit allows you to explore multiple attributes and scenarios at the speed of thought, to reach back into the prestack processing domain and forward into inversion and azimuthal domains, and to focus on the best way to address your problem rather than fitting into an established workflow.

The reservoir insight you gain in the QAI environment will inform your next move, whether in a new venture evaluation or in a producing asset.

The flexible data model takes full advantage of high-performance computing power

Don’t let slow speeds and sluggish visualization impede your creativity. Use the Sharp Reflections QAI toolkit to quickly and easily manipulate huge multidimensional prestack and poststack data volumes with unparalleled workflow efficiency.
