What makes SeisPetro’s petrophysics approach different?

SeisPetro combines conventional petrophysical interpretation with advanced data analytics, rock physics, and uncertainty analysis. This integrated approach allows workflows to scale seamlessly from individual wells to large datasets involving hundreds to thousands of wells. At regional scale, additional emphasis is placed on geological normalization, consistency across tools and vintages, and preservation of stratigraphic trends to support reliable mapping and basin-scale modeling.

​

When is Regional Petrophysics needed instead of conventional workflows?

Regional Petrophysics is most valuable when large datasets introduce non-geological variability due to tool differences, acquisition vintages, or operational practices. In such cases, regional workflows help produce stable, comparable petrophysical properties suitable for regional mapping, static modeling, and integration with seismic data.

​

These workflows form the foundation for more advanced analyses and are applied across exploration, development, and subsurface evaluation projects.

​

What makes SeisPetro’s seismic work different?

While SeisPetro performs conventional seismic interpretation, its strength lies in applying seismic workflows to lithology prediction, fracture characterization, and integrated subsurface modeling. Seismic inversion, spectral decomposition, attributes, and AVO are used not as standalone products, but as inputs to rock-physics-driven interpretation and fracture and reservoir characterization workflows.

​

How does seismic interpretation integrate with petrophysics and fracture modeling?

Seismic data are integrated with petrophysical models, rock physics diagnostics, and fracture characterization to ensure consistency between well-based interpretations and 3D seismic volumes. This integration supports lithology prediction, fracture intensity modeling, permeability estimation, and uncertainty assessment.

​

What seismic applications are commonly used for fracture characterization?

For fracture characterization, SeisPetro applies seismic attributes, curvature and strain analysis, spectral decomposition, inversion products, and orientation-sensitive measures calibrated with well and image-log data. These workflows support both continuous fracture modeling and discrete fracture network (DFN) construction.

​​​

How does SeisPetro use seismic data for lithology characterization?

SeisPetro uses seismic inversion, spectral decomposition, attribute analysis, and AVO interpretation in combination with rock physics and petrophysical calibration to predict lithology and mineral variations away from wells. Beyond conventional inversion-based interpretation, SeisPetro applies a proprietary seismic facies probability mapping workflow based on a frequentist approach, conceptually similar to an opinion poll. Instead of relying solely on Bayesian facies classification using predefined probability density functions, this method evaluates how consistently seismic responses support specific lithologies across space and scale. The result is a lithology probability model that is less sensitive to end-member assumptions and has been tested and validated across multiple geological environments.

​

What is Natural Fracture Characterization & Modeling in SeisPetro?

​

How does geomechanics factor into seismic-based fracture characterization?

Geomechanics plays a central role in SeisPetro’s fracture characterization workflows. Seismic-derived fracture indicators are interpreted within the context of the in-situ stress field, mechanical stratigraphy, and rock properties to distinguish between potentially conductive and non-conductive fractures. This integration supports fracture orientation analysis, permeability estimation, fault stability assessment, and modeling of fracture behavior under changing stress conditions.

​

In one sentence, how should SeisPetro’s seismic capabilities be described?

SeisPetro delivers conventional and advanced seismic interpretation, ranging from structural mapping to inversion and attribute analysis, with a particular focus on applications to lithology prediction, natural fracture characterization, and integrated subsurface modeling.

What is Fault Propensity to Slip or critical stress analysis?

Critical stress analysis evaluates the likelihood that existing faults will undergo slip or reactivation under current or perturbed stress conditions, such as fluid injection. SeisPetro integrates seismic fault interpretation, geomechanical modeling, and critical stress analysis to quantify slip tendency and pressure sensitivity along fault surfaces, providing reliable fault behavior assessments.

​

Why is Fault Propensity to Slip analysis important?

Understanding which faults are prone to slip is critical for risk assessment in development, injection, fault compartmentalization or stimulation projects. Slip on faults can affect reservoir performance, fault conductivity, induce seismicity, or compromise containment, so quantifying slip tendency helps support safe design, monitoring, and decision-making.

​

What data and methods are used in Fault Propensity to Slip analysis?

SeisPetro builds geomechanical models of in-situ stress state, pore pressure, and rock mechanical properties using well logs, seismic data, regional constraints, and client models when available. Interpreted fault geometries from seismic are constructed into surfaces, and critical stress analysis is performed along these surfaces to resolve stresses and quantify slip tendency.

​

When is Fault Propensity to Slip analysis used?

This analysis is valuable prior to activities that can perturb the stress field, including fluid injection (e.g., waterflood, CO₂ injection), hydraulic fracturing, reservoir depletion, or any project where changes in pore pressure or stress could influence fault stability. It is also useful to better understand fault compartmentalization. 

​
