A proven workflow

At the core of our consulting capability is our established workflow called SABRE - which stands for Systematic Approach to Basin Resource Evaluation. SABRE has been developed over many years, through an understanding of basement character beneath and adjacent to sedimentary basins, coupled with a global knowledge of tectonic events responsible for basin formation. The SABRE™ workflow emphasizes two critical elements necessary to set the framework for play-scale evaluation:

       Over 300 global projects completed.

      Over 300 global projects completed.

  • Understand the evolution of a basin from the “bottom-up” – that is, understanding the basement and geodynamic evolution of a basin system through time, i.e. how the basement (the "container") and basin evolved to their present-day configuration
  • Understand the regional tectonic drivers and events which have influenced the infill of the basin through time, thereby setting the paleogeographic framework for predicting the distribution of petroleum systems elements (reservoir, source and seal) through time

Frogtech Geoscience's unique evaluation methodology and our integrated series of workflows provide an analysis of plate reconstructions through time, tectonic drivers/events (including basin response), regional kinematics, basement terranes (age, type, composition and physical properties), tectonic provinces, basin types, basin phases (tectonostratigraphy), heatflow, petroleum systems and play elements.

Our approach is applicable and beneficial from country-scale screening to more detailed play element analysis. In addition, our approach can be used to analyse the whole spectrum of resources associated with basement (minerals and geothermal) and basin systems (conventional and unconventional O&G, minerals, coal, geothermal, groundwater and CCS).

SEEBASE consulting - Our signature basement modelling & prospectivity interpretation service

Our signature consulting service leverages the same methodology used to deliver our SEEBASE multi-client regional products. The only difference being SEEBASE consulting services give our clients the advantage of creating unique and client-confidential SEEBASE models using the client's constraining datasets as input. This allows our consultancy clients to gain a commercial advantage through SEEBASE by attaining a hand-contoured depth-to-basement model of their area of interest, prepared using their confidential data.

With over 300 global client SEEBASE consultancy projects completed, our unique service is proven to deliver the essential science needed to reduce the exploration risks of the most successful exploration companies in the world.

REAL INTERPRETATION NOT computational derivatives

SEEBASE is not constructed using a computational derivative or any other interpretive software program. Each SEEBASE depth-to-basement grid is interpreted by our PhD qualified global experts in geophysics, geodynamics and basement geology. 

Our SEEBASE methodology results in the best possible model for the 3D geometry and depth of the top basement surface. In contrast to basement models produced by inversion of one or more potential field datasets, SEEBASE is a hand-contoured interpretation. This method allows the interpreter to incorporate information from a wide range of datasets and importantly this also allows integration of our understanding of the nature of basement and our structural model of basin evolution.  A hand-contoured SEEBASE is therefore able to highlight subtle features and to integrate constraints from all the available data in a manner superior to simple gridding of depth points from seismic, magnetic and gravity data.. 

SEEBASE can be calibrated with a wide variety of datasets including processed potential field datasets, geophysical modelling, surface geology, terrane/basement geology, plate reconstructions, tectonic events, kinematic analysis, rock properties, seismic data, cross-sections and well data.

RESULTS WITH limited seismic inputs

In a cost-constrained market, seismic data is not always available for decision making, and this is where non-seismic geophysics can be employed. Our SEEBASE consulting clients benefit from being able to extend the view of the basins beyond available seismic grids by using our proprietary potential field geophysics.

Our proprietary enhancement of potential field data (principally gravity and magnetic data) provides an uninterrupted window to the basement and basins and can cover extensive areas at a constant resolution. By using potential field data in combination with outcrop, well and seismic datasets, Frogtech Geoscience can extract more geological information than would otherwise be possible using individual datasets.

results from a proven workflow

Our SABRE workflow and SEEBASE model combine to deliver unique and valuable insights for our consultancy clients, including:

  • A rapid and cost-effective framework of basement and basin evolution
  • An integrated understanding of basin-forming events, accommodation and depositional histories through time
  • Total sediment thickness, crustal structure and depth-to-Moho
  • A geologically-controlled model for basement-derived heat flow
  • Insights into the distribution and quality of source, reservoir and seal facies
  • An structural understanding of trap formation and fault reactivation histories
  • A foundation to understand exploration risks and to plan new acquisition and exploration strategies

A systematic approach to basin resource evaluation

SABRE - Systematic Approach to Basin Resource Evaluation – is the backbone of our rapid basin evaluation workflow. The SABRE methodology applies efficient and effective techniques to fast-track the evaluation and ranking of play elements using regional-scale datasets and constraining information.

The SABRE methodology begins with a big-picture analysis of plate reconstructions, structural provinces, basement terranes and regional kinematics. This regional analysis of basement character beneath and adjacent to sedimentary basins, coupled with knowledge of tectonic events, provides a foundation to move rapidly into basin and play-scale evaluations.

The SABRE methodology develops a comprehensive structural model which is built on the integration of all readily available geophysical and geological datasets and other constraining information. Frogtech Geoscience experts in geophysics, structural and basement geology, geodynamics and basin analysis work as a team and undertake multiple iterations to build the integrated structural model.

Frogtech Geoscience interpreters use potential field data (principally gravity, magnetics and DEM) extensively in our studies. The processed and enhanced potential field datasets provide a window into basement that can cover wide areas with uninterrupted data at a constant resolution. Such ‘map view’ interpretations contrast with the ‘cross-section view’ interpretations, which often result from only using more conventional industry data such as wells and seismic data. While individual datasets used in isolation can produce ambiguous results, the integration of multiple, regional-scale datasets yields a more tightly constrained model that is consistent across all available data. 

Our systematic big-picture and ‘bottom-up’ approach provides a rapid "Plates-to-Pores" view of:

  • Provinces and terranes
  • Tectonic events, basement and basin evolution
  • Petroleum systems and play elements

Frogtech Geoscience's signature product is a depth-to-basement model called SEEBASE, i.e. Structurally Enhanced view of Economic BASEment. The SEEBASE product is the culmination of an integrated geophysical and geological analysis undertaken by our interpreters.

Together, SABRE and SEEBASE deliver unique products and valuable insights for our clients, including:

  • A rapid and cost-effective framework of basement and basin evolution
  • An integrated understanding of basin-forming events, accommodation and depositional histories through time
  • Total sediment thickness, crustal structure and depth-to-Moho
  • Geologically-controlled model for basement-derived heat flow
  • Insights into the distribution and quality of source, reservoir and seal facies
  • An structural understanding of trap formation and fault reactivation histories
  • A foundation to understand exploration risks and to plan new acquisition and exploration strategies

traditional methods don't cut it

Traditional methods of processing Low Magnetic Latitude data (within ± 25° of the equator) are notoriously unsuccessful at imaging and correctly locating magnetic anomalies. Frogtech Geoscience has created a new solution with a technique to process data at low magnetic latitudes. Existing methods for transformation (RTP, RTE and AS) do not fully resolve anomaly location and often distort the anomaly shape leading to misinterpretation of data.

Frogtech Geoscience has developed the MTC-LML Filter, to accurately image the shape and position of anomalies.
Enhancement of the MTC-LML Filter in the form of ternary images helps to provide a clearer view of the magnetic anomalies and improve anomaly characterisation.

The above image has undergone Frogtech Geoscience's MTC-LML filter. The filter accurately positioned the magnetic anomalies directly over the magnetic bodies in the subsurface, anomaly shapes are accurately represented and magnetic intensities are accurate.  The accuracy of the Frogtech Geoscience MTC-LML filter over similar filters gives geoscientists confidence that their interpretations on magnetic datasets are free of false negatives and artefacts

To aid interpretation further, Frogtech Geoscience has a range of image enhancements including a ternary image enhancement shown above.  This image illustrates three different physical characteristics of the magnetic bodies, including horizontal gradients, edges, points of inflection, vertical derivatives, normalised responses and many more in the one image.  By having three different physical characteristics in one image, the efficiency of interpretation is improved.
