We provide additional expertise through our knowledgeable and experienced associates.

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. His worldwide satellite mapping experience includes SE Asia, East Africa, Myanmar, the Zagros Mountains, Mexico, the Lesser Caucasus, the Andes, the Carpathians, the Canadian Arctic, Spain and the Afghan-Tajik Basin, covering a broad range of tectonic and climatic settings. Siebe works with a combination of optical imagery, digital elevation models and radar data, acquired by satellite, airplane or drone, depending on the most appropriate data for a specific region.

Siebe’s interests lie in applying geological mapping to natural resource exploration (O&G, minerals, water). He quickly recognizes opportunities to integrate satellite data with geophysical datasets (gravity, magnetic, seismic, etc), to combine the strengths of each dataset and build more accurate subsurface geological models. At CGG, Siebe drove the integration of satellite data into the seismic processing workflow. Siebe has recently joined Marc Goossens at the geological remote sensing consultancy Geosense.
