Dr Stephen Rippington

Stephen Rippington is the Director of Astute Geoscience. He has experience working in extensional, compressional and strike-slip dominated regimes in frontier regions all over the world (Africa, the Arctic, Central and Pacific Asia, and the North Atlantic). Stephen has used his broad geoscience background in structural geology, sedimentology, geochemistry, and integrated seismic, gravity and magnetic interpretation, to manage and undertake academic and consultancy projects for exploration and service companies, universities and government departments.

Stephen’s passion has always been multi-disciplinary, multi-dataset research and interpretation. The common theme running through his work is the collection and synthesis of different data types to resolve structural problems and construct robust geological models.


Mr Siebe Breed

Siebe Breed holds a BSc degree in Geology from the VU University Amsterdam and an MSc in Geological Resources from Universidad de Oviedo (Spain). After graduating he worked at NPA Satellite Mapping (first part of Fugro, then part of CGG), where his focus was on geological mapping projects. During this time, he built satellite mapping experience worldwide, mainly in SE Asia, East Africa, Myanmar, the Zagros Mountains, Mexico, the Lesser Caucasus, the Andes and the Afghan-Tajik Basin, covering a broad range of tectonic and climatic settings. This work was done with a combination of optical imagery, digital elevation models and radar data. With earth observation technology advancing, and competition rising, the possibilities of satellite mapping continuously improve, while costs decrease.

Siebe was involved in the development of innovative uses of satellite data for geological and geophysical applications. This included the integration of satellite data into the seismic processing workflow. Siebe quickly recognizes opportunities to integrate satellite data with geophysical datasets (potential fields, seismic, etc.), to combine the strengths of each dataset, for more accurate subsurface geological models. His interests lie in applying geological mapping to natural resource exploration (O&G, minerals, water).
