Structural geology underpins much of what Getech provides: from interpretations of Potential Fields Data, through Tectonic and Structural Modelling, to Palaeogeography and Petroleum Systems Analysis.
Getech’s Structural Geology Team currently comprises eight full-time structural geologists, with associated plate modellers and geophysicists. Getech is actively expanding its capabilities in this area. Our expertise allows us to:
- Produce structurally consistent and scientifically robust interpretations at regional to sub-basin scales.
- Determine the development of structural trap formation, including structural geometry, kinematics and timings, tied into our regional and global tectonic solutions.
- Verify these interpretations using our Global Plate Model alongside restorations of our constructed profiles and your proprietary seismic data.
Getech’s structural geology expertise is used throughout Globe, Regional Reports and Commissions to produce structural interpretations from Getech’s world-leading Gravity and Magnetic databases in addition to Landsat, SRTM (topography), bathymetric, and other data.
At regional scales, the interpretation of structures, such as faults and folds, is used to define plate boundaries in the Global Plate Model, with the additional integration of the Getech Crustal Architecture Database that defines crustal types using 2D gravity and magnetic profiles.
Structures are also integrated into the Getech Globe palaeogeographies using their individual activation histories; these histories enable their phases of activity to be linked to the relevant times in the past. The attribution of structures and their activation histories includes a comprehensive audit trail that provides users with information on mapping, age confidence, and a full explanation of the basis of each feature (i.e. what data was used to define it).
At higher resolutions, Getech’s expertise can be used in the structural analysis of leads, plays or prospects, and in the identification of potential structural hydrocarbon traps. Interpretation and integration of proprietary seismic data with Getech’s gravity and magnetic data allows the finer details obtained from seismic data to be extrapolated over wider areas.
The input of horizon and fault interpretations from seismic data refines the production of our 2D profiles that constrain our crustal architecture and the geometry of the crust in the area of interest.
Restorations give a clearer understanding of the structural evolution of an area and structural trap formation. Getech structural restorations are undertaken on both proprietary data and on our own 2D profiles in order to validate interpretations and constrain the structural development of the region. The tectonic episodes identified can be tied back directly to the evolution of the region within the plate model.
Our structural interpretations are the result of years of workflow development to produce a user-friendly result. This is combined with an in-house Structural and Tectonic Research and Development Group so that our knowledge and interpretations are kept up-to-date with the current science.
