What We Do

CCS Site Evaluation & Monitoring

Rigorous assessment of storage reservoirs, cap-rock integrity, and long-term containment — for every phase of the CCS lifecycle.

Carbon Capture and Storage (CCS) requires rigorous assessment of storage reservoirs, cap-rock integrity, and long-term containment. dGB's tools support every phase of the CCS lifecycle — from site screening to injection monitoring and post-closure surveillance.

OpendTect's chimney detection technology, originally developed for hydrocarbon exploration, is ideally suited for identifying potential leakage pathways in cap-rock formations — a critical safety requirement for CCS projects.

Key Workflows for CCS

Storage Site Screening

Evaluate potential storage formations using seismic attributes, well data, and machine learning to assess reservoir quality and capacity.

Cap-Rock Integrity Analysis

Detect faults, fractures, and fluid migration pathways through the seal using chimney detection and fault likelihood attributes.

4D Seismic Monitoring

Monitor CO₂ plume movement and pressure changes over time using time-lapse seismic interpretation and difference attributes.

Fluid Migration Pathway Detection

Use dGB's chimney detection technology to map vertical fluid pathways and assess containment risk.

Reservoir Characterization

Predict porosity, permeability, and injectivity using AI-driven seismic inversion and SynthRock pseudo-well modeling.

Risk Assessment

Integrate fault networks, seal quality, and predicted fluid behavior to quantify storage risk and inform regulatory submissions.

From a Recent CCS Project

Selected highlights from a recent storage-site evaluation showing how seismic conditioning, rock physics and inversion combine to de-risk a CO₂ storage candidate.

Integrated CCS Workflow

A two-phase project flow — from seismic well tie and spectral conditioning to fault detection, rock physics, AVO and elastic inversion.

Flatness of AVO Gathers

Constructed pre-stack gathers confirm key reservoir events are essentially flat across offset, validating AVO-compliant inversion inputs.

Rock Physics Prognostics

Acoustic impedance vs. Poisson ratio crossplots colour-coded by V-clay and porosity isolate porous sand from silt and shale.

Inversion QC at Blind Wells

Crossplots and real-vs-synthetic trace overlays demonstrate inversion fidelity, including at a blind well (CC 0.99, SNR 44.9).
