PQRS (Pre-stack Quantitative Reservoir Study) Workbench is an integrated geophysics and geomechanics platform that unites pre-stack elastic inversion, rock physics modeling, stress analysis, wellbore stability, and machine learning — all in a single, lightweight environment.
Most geophysics platforms stop at inversion and rock physics. We go further — connecting seismic data directly to drilling engineering decisions.
Predict collapse and fracture pressure with 3D geomechanical models. Optimize mud weight windows for safe and cost-effective drilling — a capability rarely found in seismic interpretation platforms.
⭐ Unique StrengthQuantify fracture orientation and intensity using wide-azimuth OVT data with elliptical fits. Essential for unconventional reservoir characterization and hydraulic fracturing design.
⭐ Unique StrengthAssess fault slip tendency and fracture reactivation risk using stress polygon analysis. Critical for CO₂ sequestration, geothermal projects, and reservoir geomechanics.
⭐ Unique StrengthMultiple inversion methods in one platform — AVO three-term, Aki,Fatti, Gray, Zong ,AVA simultaneous inversion. Compare results side by side to find the best fit.
Model hydraulic fracture propagation and direction turning under in-situ stress conditions using DDM (Displacement Discontinuity Method). Optimize perforation azimuth and stage design for maximum fracture network effectiveness.
⭐ Unique StrengthSVM, SOM, and PCA for well-seismic integration and reservoir property prediction. Train on well logs, predict on seismic volumes — no external ML tools needed.
From seismic data processing to drilling engineering — PQRS Workbench covers the full geoscience workflow.
