Night School – Deep-Water Deposystems and reservoirs (Virtual Course)

High quality training to boost professional development. Courses are exclusive to PESGB members only.

24 March - 14 April 2021

Course Description

The program consists of four online 2-hour seminars, followed by Q&A, delivered by instructor Professor Bryan Cronin. The format is primarily by lecture through interaction is encouraged through the sessions. The program is focussed on G&G characterisation of deep-water deposystem reservoirs, using a wide range of subsurface, seafloor and outcrop analogues to define the scenarios you may encounter anywhere in the world. Examples from west Africa, offshore Latin America/Caribbean, Bay of Bengal, North Sea, Mediterranean, South China Sea and the Gulf of Mexico are all used – and have all been worked on by the instructor himself. The thrust of the program is to promote confidence-building in establishing what type of deep-water deposystem you have on seismic, the reservoir story that you have there, and what you need to define the ranges of reservoir properties and reservoir scenarios, as a basis for creating robust GDE maps, conceptual models, and ultimately, reservoir models.

Speaker Biography - Bryan Cronin


Bryan Cronin is a geologist with over 30 years of technical experience with deep-water turbidites at outcrop, on the sea floor and in the subsurface. He is currently principal geologist for Tullow Oil, in the Exploration Department, based in London.

He was an independent consultant (2005-2016), working on deep-water reservoirs in the North Sea, Africa, SE Asia, South America, the former Soviet Union and in other areas. He has run over 103 commercial field courses to the Alps, the Pyrenees, California, Ireland, SE Spain, NE and S England, and Turkey between 1996 and 2019. He instructed for Petroskills and Nautilus and ran week-long classroom-based courses on Turbidite Reservoirs, Sandstone Reservoirs, Basic Petroleum Geology amongst others. He is Honorary Professor at University of Aberdeen, The Robert Gordon University and Hangzhou Petrochina Institute for Petroleum Geology.

He is still involved in education and training with MSc and PhD students and oil company employees, most recently with the PRACCS research group where he was joint principal investigator with Professor Ben Kneller, working in southern Chile, Turkey, France, Argentina, Tibet and Mexico.

Professor Cronin was awarded the William Smith Fund by the Geological Society, London, in 2007.

His list of publications is extensive and in most mainstream peer reviewed journals.
