INTEGRATED EVALUATION

From the surface signal to the petroleum-system model

Rather than analyzing each dataset in isolation, the integrated evaluation combines direct hydrocarbon measurements with the operator's geology, seismic and well data to characterize the hydrocarbons and interpret generation, migration, reservoirs, seals and traps.

Well data

What the operator receives

Integrated petroleum-system model

Generation, migration, reservoirs, seals and traps interpreted together, from the operator's data and the geochemical response.

Prospectivity maps

Spatial distribution of the hydrocarbon response, with phase identification: oil, gas and condensate.

Priority targets

Ranking of areas and locations to guide drilling.

Lower risk, optimized CAPEX

A stronger technical basis for drilling and investment decisions, reducing the risk of multimillion-dollar losses.

An approach with international validation, with results compared against drilling and production data.

METHOD

An independent layer of hydrocarbon response

Passive surface geochemistry registers gas-phase hydrocarbon molecules associated with the natural molecular migration of the subsurface petroleum system toward the surface.

At points defined by the survey design, passive adsorption modules are deployed to register that molecular signal, without the need for conventional soil sampling. After recovery, the modules move under chain of custody to laboratory analysis, specialized processing and interpretation.

The compositional patterns identified, analyzed at the molecular level and by clusters, are turned into an independent layer of geochemical information, which can be integrated with geology, seismic and well data to broaden the technical basis for exploration, appraisal, development and field-revitalization decisions.

How a project is executed

Project information review and analysis

Available data, operator objectives and area context define the survey strategy.

Technical survey design

Survey area, sampling grid, calibration points and field requirements, aligned to the project objective.

Surface geochemical acquisition

Passive-module deployment, GPS positioning, documentation, field QC, recovery and chain of custody.

Laboratory analysis and processing

Specialized laboratory analysis (thermal desorption and GC/MS), molecular and cluster analysis, and processing of the compositional response recovered from the passive modules.

Integrated interpretation and decision support

Results are integrated with the operator's geology, seismic and well data, generating the petroleum-system model, prospectivity maps and priority targets for the decision.

APPLICATIONS

Where geochemistry can support the operator's decision

Every operator faces a different technical problem. The applications below are independent — a project does not need to move through all of them for the method to be useful.

Block and petroleum-system evaluation

Characterizing the hydrocarbons and interpreting generation, migration, reservoirs, seals and traps, integrating geochemistry, geology, seismic and well data.

Screening and prioritization of blocks, leads and prospects

Ranking opportunities based on hydrocarbon response, before committing significant technical budget — including in preparation for licensing rounds and auctions.

Uncertainty reduction ahead of drilling

An independent layer of information ahead of high-cost drilling decisions and dry-well exposure.

Seismic optimization and integration

Directing 2D lines, focusing 3D acquisition, and integrating with existing seismic interpretation.

Appraisal and field development

Supporting delineation, field extensions and prioritization of the next drilling stage.

Mature fields and production optimization

Identifying sweet spots, infill targets, workovers and revitalization in producing fields.

Complex geology and difficult-access areas

Thrust belts, channel sands, multiple petroleum systems, desert and steppe terrain, wetlands, rugged terrain and low temperatures — with low-impact, minimal-disturbance field deployment.

Economic risk reduction and CAPEX optimization

One more technical argument before committing significant budget — to prioritize drilling and direct seismic investment.

AGI technology · Global CCS Institute

Application area: CO₂ storage monitoring

The same passive-adsorption principle of surface geochemistry used in oil and gas exploration is applied to CO₂ monitoring: baseline measurements before injection and detection of possible leakage along wells and faults. The technology is AGI’s; SGEEurasia works in cooperation with AGI.
