Questions?​

Frequently asked questions

Clear and concise answers to the most common questions about our rock physics analysis and seismic inversion services, supporting reliable reservoir characterization and decision-making.

We deliver rock physics modeling, well–seismic calibration, elastic and acoustic seismic inversion, and integrated interpretation workflows to predict reservoir properties.

Typical inputs include well logs, core data (if available), seismic data, wavelets, velocity models, and existing interpretations. Data QC and conditioning are part of our workflow.

 These workflows link seismic response to rock and fluid properties, enabling quantitative prediction of lithology, porosity, and fluid distribution away from wells.

We perform acoustic, elastic, pre-stack, post-stack, deterministic, and stochastic inversions, selected according to data quality and project objectives. 

Deliverables include inverted property volumes, rock physics templates, well-to-seismic ties, interpretation maps, uncertainty analysis, and a comprehensive technical report.
