RockMod® performs multiple stack (AVO/AVA) geostatistical reservoir characterization to produce multiple highly detailed models through tightly integrating disparate data across all pertinent geoscience domains. The outcome is accurate reservoir models in depth for prediction of field reserves, fluid flow patterns, and future production. RockMod is relevant where dual or triple parameters like P-Impedance, S-Impedance and Density are needed to distinguish the facies of interest.

Benefits of RockMod:

• Produces accurate and predictive reservoir models that are consistent with all data and knowledge available in the field
• Generates highly detailed, multiple realizations to provide a reliable basis for quantitative measure of uncertainties associated with data, models and thin beds.

StatMod® performs single-stack geostatistical reservoir characterization to produce multiple predictive, fine-scale reservoir models that are consistent across all pertinent geoscience domains. This degree of cross-domain consistency ensures that reservoir models are realistic and maximizes the value of all measured data and inferred information. In addition, these reservoir models remain accurate away from the available well control where the reliability of conventional stochastic models typically suffers. StatMod is relevant where a single parameter like P-Impedance is sufficient to distinguish the facies of interest.

Benefits of StatMod:

• Produces accurate and predictive reservoir models that are consistent with all data and knowledge available in the field
• Generates multiple, highly detailed realizations to provide a reliable basis for quantitative measure of uncertainties associated with data, models and thin beds

RockTrace® quantitatively integrates well log elastic rock properties and AVA seismic to produce calibrated, quantitative 3D volumes of rock properties. This module determines key reservoir properties, P-impedance, S-impedance, density and Vp/Vs, through the inversion of partial offset or angle stacks. RockTrace AVO inversion integrates sparse spike inversion technology with sophisticated low-frequency modeling techniques to produce the most advanced deterministic estimates of reservoir properties in the industry.

Benefits of RockTrace:

• Consistent, accurate reservoir properties
• Realistic low-frequency models consistent with geology
• Fewer and better wells drilled
• Exploration and production goals met
• Optimum development of reservoirs
• Accurate reserve estimates

Facies & Fluids Probabilities (FFP) is an interactive interpretation tool for determining lithofacies from the outcomes of acoustic and elastic inversions. Facies are usually defined in the petrophysical domain, after which proxies are confirmed in the elastic domain. Typically, P-impedance and Vp/Vs are used. For unconventional scenarios, the key elastic proxies could be geomechanical.

Benefits of FFP:

• Optimize reservoir appraisal and assessment with probability-based QI interpretations
• Generate facies maps that are meaningful to geologists
• Discover unknown facies

Anisotropic Inversion is a Jason-exclusive seismic inversion module that applies new analysis technology for effective well design and optimum production. Anisotropic Inversion is built on proven RockTrace® technology and seamlessly integrates within the GeoSoftware platform. The Jason-patented relation between elastic dependence and anisotropy allows Quantitative Interpretation (QI) teams to more accurately characterize reservoirs that have significant anisotropy. Oil companies can now take advantage of the reservoir information in azimuthal seismic surveys to define optimum reservoir drilling locations.

Benefits of Anisotropic Inversion:

• Build advanced predictive reservoir models
• Understand premature water breakthrough in shale and fractured carbonate reservoirs
• Improve well planning in shale and in fractured carbonate reservoirs

DepthMod™ is a velocity model calibration application that ensures calibrated models can be used to convert time data (inversions) to depth models that ties well tops.

This module can calibrate velocity functions for use in re-depthing – ensuring that depth volumes provided by clients tie wells. Designed for engineers and quantitative interpretation teams who must plan wells in depth, DepthMod can obtain accurate reserve estimates and enable well planning in depth.

Complex, fully 3D models incorporating lateral velocity changes and faults can be used to deliver accurate time-to-depth conversions about user-defined time and depth datums.

The Multiple Attribute Well Interpolator (MAWI) adds geologically consistent detail to reservoir characterization by using external trends to drive interpolation of lateral changes beyond well control.

Environment Plus combines the most commonly used tools within the Jason Workbench into a single, tightly integrated platform for use in workflows and studies with all of the core features necessary to begin a quantitative reservoir characterization workflow. Included in this package are the visualization tools, BodyChecking, Crossplots and Histograms, 2D Interpretation, horizon and fault data management, WellTie, and Processing Toolkit.

WellTie is a well-to-seismic tie and wavelet estimation application and provides industry-leading capabilities for the integration of well and seismic information.

WaveletTools enables Quantitative Interpretation specialists to facilitate the interpolation of spatially-varying wavelets and provides Q compensation functionality. In this module, it is also possible to design deconvolution filters for zero-phasing seismic or for designing operators to perform Colored Inversion.

With Jason’s Depth Inversion process, it is possible to process large data sets in depth without copying data into time. Time-to-depth conversion runs in the background as required using Jason’s On-the-Fly (OTF) technology.

InverTracePlus post-stack inversion integrates sparse spike inversion technology with sophisticated low-frequency modeling techniques to produce the most advanced deterministic estimates of P-impedance in the industry.

The Multi-Realization utility allows the user to simultaneously generate multiple realizations on multiple machines to dramatically reduce the execution time of StatMod and RockMod batch runs.

Multi-CPU (MCPU) facilitates the networking of hundreds of PCs and Linux machines to ensure the fastest throughput of inversion projects and helps to dramatically cut the execution time of InverTrace Plus and RockTrace batch jobs.
