Dr Paul Dodsworth
B.Sc. (Hons) M.Sc. Ph.D.

Palaeo⁷ LLP Delegated Partner Representative

Paul is a geologist with expertise in the Upper Jurassic, Cretaceous and Cenozoic palynology and stratigraphy of Europe, North and South America, the Middle East and Africa. He was awarded an M.Sc. in palynology from the University of Sheffield, U.K., in 1992 and stayed on at Sheffield to undertake a Ph.D. in mid-Cretaceous stratigraphy which was awarded in 1997. In 2001, he received the inaugural Charles Downie Award from The Micropalaeontologial Society for research published from his thesis.

Since 1996, Paul has worked as full-time biostratigraphic consultant to the oil and gas industry. From 1996 to 2006, he was employed as a palynologist by Robertson Research, Millennia Stratigraphic Consultants and Ichron. While at Ichron, he was a West of Shetland wellsite stratigrapher, analysing in real time pilot holes and development wells from the Foinaven, Schiehallion, Loyal and Clair Fields. He founded StrataSolve Ltd in 2006, a company specialising in palynological assistance with the geo-steering of ‘horizontal’ oil wells, particularly in the Central North Sea, UKCS. He has to date analysed over 90 offshore wells at site. Since 2011, he has also assisted three oil companies with in-house palynological calibration and palaeoenvironmental studies of Cretaceous unconventional shale reservoirs in North America, particularly the Eagle Ford Group in Texas.

In 2018, Paul co-founded Palaeo⁷ LLP to address market demand for a larger multi-disciplinary highly-experienced team to provide relatively rapid turnaround on post-drill analysis projects. Going forward, his multi-disciplinary international work will be channelled through Palaeo⁷.

Paul maintains research links with the University of Sheffield, the University of Kingston, London, and Shell’s Eagle Ford Research Group. He is a reviewer of palynology-based manuscripts for six international journals.
