Dave has 21 years’ experience in petroleum industry consulting. He completed a Ph.D. on Early Cretaceous nannofossils of the North Sea and Barents Sea (London, 1994) and has worked on Cenozoic, Cretaceous and Jurassic sections practically worldwide, with particular experience in the in the North Sea (Danish, Norwegian & UK sectors), eastern Canada, Trinidad, the US Gulf of Mexico, Brazil, and throughout the West African margin. He is especially familiar with the post-salt biostratigraphy and sequence stratigraphy of the South Atlantic Margins (offshore Brazil, West Africa and eastern Trinidad). Dave has provided wellsite nannopalaeontology services on more than 55 wells in the North Sea (Danish, Norwegian & UK sectors), eastern Canada, the US Gulf of Mexico, Trinidad, Mauritania, Sierra Leone, Liberia, Cote D’Ivoire, Cameroon, Mozambique, Egypt, Oman and Brunei. His wellsite assignments have included ‘biosteering’ of horizontal development wells, casing picks (including HP/HT wells), and long duration overseas jobs in structurally complex settings (more than 4 months on a single well in Trinidad). Additionally, Dave has travelled to Angola and Brazil to conduct rapid-turnaround analyses, and provided training courses in Malaysia and South Africa.
Simon has 11 years’ experience in petroleum industry consulting. He completed a M.Sc. in Micropalaeontology (London, 2004) that involved a long project on Paleocene-Eocene nannoplankton of the northwest Pacific. Simon has significant wellsite experience, having conducted wellsite micropalaeontology and nannopalaeontology on more than 20 Danish wells, and wellsite nannopalaeontology on numerous assignments in the UK Sector (~10 wells), Gulf of Mexico, offshore Newfoundland, Trinidad, East and West Africa, and the South China Sea. Since joining PetroStrat in 2006 Simon has focussed entirely on nannopalaeontology and rapidly built experience in Cenozoic to Triassic aged sections and has analysed over 200 Cenozoic and Cretaceous well sections from diverse regions including the North Sea, Greenland, North, South East and West Africa, Middle East, Trinidad, Mexico, Argentina, Brazil, South China Sea, Brunei, Australia, Eastern Europe and onshore USA.
Tamsin joined PetroStrat in March 2010 and has over 8 years’ of experience in petroleum industry consulting. She attained a M.Sc. in Micropalaeontology from University College London (2007), having completed a long project in Late Eocene nannofossils from the Mississippi coast, USA. Since joining PetroStrat, Tamsin has gained significant experience in global nannopalaeontology (including South, East and West Africa, South America the Gulf of Mexico and Europe) and extended her knowledge of North Sea stratigraphy within the UK, Denmark and Norway. As well as extending her knowledge in Neogene nannopalaeontology, she has also built on her Palaeogene and Mesozoic experience globally, most significantly, the Middle to Late Jurassic of the Gulf of Mexico). Fully certified for offshore work, Tamsin has conducted 26 wellsite deployments in the Danish, British and Norwegian sectors of the North Sea, including coring jobs, casing picks, horizontal reservoirs (biosteering), exploration and HP/HT wells.
Marina joined PetroStrat in October 2013, following a PhD in Nannopalaeontology. She completed her B.Sc. (December 2006), M.Sc. (April 2009) and Ph.D. (April 2013) in Universita’ “G. D’Annunzio”, Chieti (Italy). For her M.Sc. thesis Marina worked on Oligocene-Miocene Atlantic Ocean deep-sea sediments recovered on ODP Leg 154 (Sites 925-926), carrying out a stratigraphic and biometric study on calcareous nannofossils using image analysis software. Marina’s Ph.D. research project focussed on the morphometry, evolution and paleoecology of Miocene-Pliocene Discoaster and Catinaster species in the Pacific Ocean (IODP Exp. 321, Site U1338). The results of her Ph.D. thesis have been published. After joining PetroStrat, Marina carried on working Neogene sections from the US Gulf of Mexico, East and West Africa. She also gained significant experience in Palaeogene and Cretaceous calcareous nannofossil biostratigraphy, having worked on West African Cretaceous sections from Ghana, Liberia, Côte D`Ivoire, Angola, Cameroon and recently on sections from offshore US and offshore Brazil. Marina now has significant experience in East Africa, having worked on various Neogene, Palaeogene and Cretaceous sections in Tanzania and Mozambique, including 2 wellsite assignments in Mozambique. In addition she has recently worked offshore in the UK North Sea, monitoring the stratigraphy of a HP/HT well and in the Gulf of Mexico, Miocene-Paleocene interval.
Jennie joined PetroStrat in September 2014 after gaining an M.Sc. in Applied and Petroleum Micropalaeontology from the University of Birmingham. As well as gaining a broad understanding of the application of biostratigraphy, Jennie completed her M.Sc. thesis focusing on Middle Miocene Calcareous nannofossils from the Caribbean Sea, in relation to changing climatic perturbations. Since joining PetroStrat Jennie has extended her knowledge throughout the Cenozoic with particular focus in the Neogene, studying sections from the Gulf of Mexico, Mexico, Caribbean (offshore Colombia, Trinidad, Barbados), Africa and Australia. She has also broadened her skill set to include the Paleogene of East Africa, Turkey and the Middle East, along with the Late Cretaceous of Canada, West and East Africa. Jennie is certified for wellsite duties.
David joined PetroStrat in October 2014, after completing an M.Sc. in Applied and Petroleum Micropalaeontology at the University of Birmingham. His M.Sc. research project focused on Early Jurassic nannofossil biostratigraphy from an outcrop section located in Somerset, UK, with a specific interest in environmentally driven assemblage changes across the Toarcian oceanic anoxic event (T-OAE). His results demonstrated that calcareous nannoplankton were profoundly affected during the T-OAE by a variety of ensuing environmental changes including; global sea level, stratification, anoxia, alkalinity and nutrient availability. Since joining PetroStrat, David has rapidly gained experience in both Cenozoic and Mesozoic nannopalaeontology and biostratigraphy from a variety of regions, including the U.K, West, East and North Africa, Australia, Colombia and North America. David is fully certified for offshore work and has wellsite experience within the North Sea including HP/HT wells.
