Integrated Interpretation Services (IIS)

Taking the data further

ARKeX's IIS team of highly experienced geologists and geophysicists can review your current knowledge base and improve it with a consistent and comprehensive integration of all relevant and available data to deliver an improved Earth model.

The subsurface can be better understood

ARKeX IIS can deliver:

• An enhanced, consistent, comprehensive structural and material property interpretation using all available data (seismic, borehole, gravity gradiometry, gravity and magnetic data)
• A report covering the development of the fully integrated Earth model, highlighting the relative dominance of each measurement to the result and a critical uncertainty review
• Improved collateral to aid the reprocessing of existing seismic data using the incorporation of potential field measurements into the velocity modeling operation
• A truly multidisciplinary approach, ensuring model consistency with the opportunity for crossvalidation between geophysical disciplines
• Collective acceptance of Earth model through collaborative workflows, with the significant benefit that the Earth Model is understood and agreed upon by all stakeholders

Applications

Integrated velocity-density-structure modelling

This fundamental stage of an Earth modelling programme is often applied using conventional gravity surveys to define basin scale context of a model. When implemented using high resolution gravity gradiometry measurements the benefit is seen at scales from basin architecture to near surface modelling.

Petrophysical analysis

With a structural model in place there is scope to develop locally relevant joint attributes. Useful to identify anomalous material properties, IIS geophysicists can work with your team to help identify anisotropic character, overpressure distribution and compartmentalisation.

Gravity gradiometry and Seismic velocity

A gravity gradiometry survey returns a very high bandwidth measurement of the gravitational field. This high bandwidth measurement enables the development of a subsurface density model with a resolution close to that of seismic velocity analysis. This knowledge allows the construction of a rock physics template based on seismic velocity and gravitationally derived density without the measurement scale inconsistency that plagues the integration of multidisciplinary geophysical measurements.

A well constructed relationship between seismic velocity and density is critical to the integration of gravity measurements into the seismic Earth model. Meaningful modifications may be made to the model driven by anomalies in both density and velocity, with the independence of each measurement giving the opportunity for both cross constraint and cross validation.

ARKeX IIS geophysicists have significant experience in both the technical and project management necessary to implement an integrated velocity-density model development programme in collaboration with seismic providers and asset teams.
