Geology Consultant
Exploration for hydrocarbons and their development has become more challenging with each passing decade. Play fairways are more remote, trapping scenarios more complex, reservoir presence and petrophysical characteristics are more difficult to predict with certainty.
Understanding the geology of the areas of interest becomes more important than ever.
The depositional architecture of the sedimentary environments, facies distribution, tectonic evolution and diagenetic history all have an impact on hydrocarbon volume and flow potential.
We attempt to reach this knowledge by combining traditional geological analysis and modern technology to produce robust models that can help in the exploration for new prospects, field development plans and identification of infill opportunities in mature fields.
Geology Services:
Geomodeling, Volumetric analysis, Fractured Reservoirs, Basin Analysis, Sedimentology, Log correlation, Sequence Seismic Stratigraphy, Well Planning, Structural Restoration.

Geomechanics Consultant
Geomechanics is used to analyse drilling risks, pre-drill, during drilling and post-drilling. By integrating technical data from geology, petrophyscis and reservoir engineering data models in 1D, 3D and 4D can be developed that are useful to drilling. Well bore stability is affected by rock stresses that can cause a collapse.
Safe well trajectories can be identified in a 3D geomechanical field and completions can be designed that will withstand production-induced compaction.
At the reservoir level, geomechanical models can be used to analysis pore pressure, fault and top seal integrity, compaction, subsidence, and the effects of injection / depletion on cap rock behaviour.
Geomechanics Services:
Pore pressure analysis, Wellbore stability studies, Reservoir Top seal integrity analysis, Rock Failure Analysis, Stuck pipe assessment, well trajectory modeling, Mud weight and loss assessment, Fault integrity analysis.

Petrophysics Consultant
GAS Subsea offers expert petrophysical analysis for exploration, appraisal and development wells including desktop studies, reviews, and real-time interpretation.
Interpretation of petrophysical data can have a profound impact on the volume of hydrocarbons in place and a thorough understanding of the logs is vital. Not only individual log interpretations but the combination of multiple logs in the context of reservoir type (e.g. clastic/carbonate) requires experience and a rigorous approach.
GAS Subsea can provide individual interpretations to correlation and analysis of log data which can be built into an audited database of wells. This can be combined with other subsurface data from geophysics, geology and geomechanics to models useful for dynamic modelling and drilling.
Petrophysical Services:
Saturation Hight function analysis, Rock typing & Volumetric, Borehole image analysis, Multiple software Expertise, Thin Bed Analysis, Extensive instrument log analysis, Advanced Interpretation.
