Anisotropic Inversion is Jason-exclusive seismic inversion software that applies new analysis technology for effective well design and maximum production. Anisotropic Inversion is built on proven RockTrace® technology and seamlessly integrates within the GeoSoftware platform. This includes the key components, Jason® Workbench, PowerLog® and EarthModel® FT.
The anisotropic inversion workflow using RockTrace® and Elastic Volume Evaluator derives reservoir anisotropy measures using advanced Jason technology to:
When azimuth-oriented offset or angle gathers are available, RockTrace is used to produce a set of elastic volumes – one for each azimuth. For typical acquisition scenarios, Vp/Vs is the key output (see figure) although density can also be included.
Anisotropic Inversion allows you to take the set of elastic volumes as inputs and model anisotropic information from them. Important in this is the Jason-patented relation between elastic dependence on azimuth and anisotropy. Anisotropy magnitude and orientation will be output.
A number of new QC and visualization tools are now available to support azimuthal inversion. These include:
