Geoscience Solutions Since 2003 · Houston, Texas

Reservoir answers you can defend — from seismic data you can trust.

TraceSeis integrates well-log and seismic data to deliver quantitative estimates of reservoir and geomechanical properties — reducing risk in exploration and development decisions through rock physics, seismic inversion, and proprietary software.

Our Approach

Risk reduction is a workflow, not a product.

Every engagement verifies two things before any inversion is run: that the rocks are sensitive to the property you care about, and that the seismic data faithfully represents the earth's reflectivity. Only then do we quantify.

STEP 01

Feasibility & Rock Physics

A rock physics study with SeisRP® evaluates whether changes in porosity, lithology, or fluids would actually be observable in your seismic data — before you spend on inversion.

STEP 02

Data Conditioning & QC

Pre-stack data is conditioned and verified against synthetics computed in the rock physics study, ensuring the seismic response represents true earth reflectivity.

STEP 03

Inversion & Quantification

Optimum rock properties are computed through seismic inversion, verified at well locations, and transformed into reservoir and geomechanical properties you can act on.

POLISH™ — Log Preprocessing Platform

Your interpretation is only as good as your logs.

POLISH™ is TraceSeis' wireline data preprocessing platform — transforming raw LAS files into pristine, analysis-ready datasets before they ever touch your rock physics workflow. Garbage in, garbage out; POLISH exists so it's never garbage in.

  • Denoising with the right algorithm per curve — wavelet shrinkage (Daubechies/Coiflets), bilateral filtering for edge preservation, Savitzky-Golay, and median filtering — selected automatically by curve type, with full parameter control.
  • Intelligent gap filling — Gaussian Process interpolation with uncertainty quantification, kriging with variogram modeling, cubic spline, and multi-curve correlation; zone-aware so geological boundaries are respected.
  • QC, identification, and standardization — IQR-based outlier detection, automated mnemonic and curve identification with fuzzy matching, unit standardization (including % → v/v for porosity and saturation families), and physics-informed validation. Reads and writes LAS, CSV, and Excel; SEG-Y export in development.

POLISH™ is currently in active development. Capabilities described reflect the current build.

CONFIRM™ — independent validation for AI classification models.

⊘  CONTAINS ZERO AI

Overall accuracy hides domain failure. A model can score 84% and still fail an entire customer segment. CONFIRM grades model consistency across domains using pure statistics — chi-square and Cramér's V — methods that predate machine learning by decades and can be reproduced by any auditor with a pencil and a contingency table.

Built on the same discipline TraceSeis has applied to seismic data for 20+ years: never trust an estimate you haven't independently verified.
