22 June - 1 July 2021
Session 1 | EoCambrian to Tertiary sediments and tectonics of Southern Oman
Facilitator: Stuart Harker
Date: Tuesday 22 June 2021
10:00am – 12:00pm
- Southern Oman has world class outcrops of Eocambrian to Tertiary sediments – 600Mya of Rock Record
- One of the oldest working petroleum systems in the world is present in the Huqf Group
- Reservoirs range from glacial clastics to marginal marine stromatolitic carbonates
- Traps range from conventional fault blocks through salt induced anticlines to rafted carbonates
- In spite of almost 70 years of exploration there remain many opportunities to discover additional reservoirs and traps
- Background to Field Work
- Stratigraphic Framework
- Eocambrian outcrops and hydrocarbons
- Palaeozoic outcrops and hydrocarbons
- Mesozoic outcrops and hydrocarbons
- Tertiary outcrops and hydrocarbons
- Tectonics Summary
Session 2 | Aeolian sediments
Facilitator: Richard Steele
Date: Thursday 24 June 2021
10:00am – 12:00pm
There are four parts to this show.
- The variety of aeolian systems, ancient and modern, near and far. You will learn why aeolian sedimentary systems have a greater diversity and are far more common than any other.
- The sedimentology of aeolian systems, working from the small scale – how dunes work and may be interpreted, to the large – how formations are constructed and may be interpreted. The flow structure of aeolian reservoirs will emerge from this.
- There will be examples of oil and gas in aeolian reservoirs. Some of the stories are old now, but still good. There will be a remarkable and exciting new story too. In some cases the news, good or bad, is related to the reservoir facies; others are more general stuff-that-happens when corporations try to get oil and gas out of the ground.
- A short section on dunes and climate change.
There will be lots of pictures and we will clock up quite a few miles on Google Earth
Session 3 | Shallow Marine sediments of the Pyrenees
Facilitator: Gary Hampson
Date: Thursday 01 July 2021
10:00am – 12:00pm
This two-hour workshop will remotely visit the Cretaceous to Eocene shallow-marine deposits
(Baronia Formation, Aren Sandstone Formation, Roda Sandstone Member) of the Southern Pyrenean foreland basins of northern Spain. It will illustrate through worked examples and short exercises the value of these outcrops as analogues for hydrocarbon reservoirs and CO2 storage units. At the end of the workshop, participants will be able to:
- appreciate the influence of tectonic setting on shallow-marine process regime (waves vs. tides vs. riverine currents);
- relate shallow-marine process regime, relative sea-level history and sediment routing to heterogeneity types and organisation;
- characterise the types, geometries and spatial arrangement of heterogeneities across a range of length scales;
- consider the impact of these multi-scale heterogeneities on potential reservoir behaviour.
Speaker Biography - Stuart Harker
Stuart holds BSc, MSc and PhD degrees in geology, has over 40 years exploration and production experience and is a Chartered Geologist. In his career with Texaco, Aramco, Occidental, Elf, Total and Circle Oil, he worked many basins around the globe and was involved in finding and producing oil and gas fields in Canada, Australia, Oman, Pakistan, Morocco , Egypt and the North Sea. He has held positions in several management roles, taking early retirement from Total in 2004 to be a consultant before joining Circle in 2008. He retired in 2015 and established Morningside Petroleum Geology as his own consulting company in Edinburgh. Stuart has published over 20 articles on oil and gas exploration and development and has taught on the MSc courses at Aberdeen and Heriot Watt Universities. He has served as Aberdeen Representative and 1st Vice President for the PESGB (1989-1991, plus 4 years as European Representative on the Advisory Committee then two years as VP Regions (International, 2011-2013) for the AAPG. Stuart has also served on the AAPG Grants in Aid Committee, as an associate editor for the AAPG bulletin and is currently a Visiting Geoscientist for Europe.
Speaker Biography - Richard Steele
After a sedimentology PhD, Richard worked for BP, Shell, Enterprise Oil, Nautilus, BG Group and Tullow Oil between 1982 and 2020. First as a naive sedimentologist, progressing to production or development geologist, team leader, peaking at the dizzy height of Head of Development Geoscience, then development geologist again. There were some really neat rocks in that time. The new phase is active retirement.
Speaker Biography - Gary Hampson
Gary Hampson is Professor of Sedimentary Geology in the Department of Earth Science and Engineering, Imperial College London. He holds a BA in Natural Sciences from the University of Cambridge and a PhD in sedimentology and sequence stratigraphy from the University of Liverpool. After undertaking post-doctoral research at the University of Würzburg, Germany and Imperial College London, Gary was appointed to a lectureship at Imperial College London in 2000. He teaches clastic sedimentology, sequence stratigraphy, and petroleum geology at undergraduate and postgraduate level, and is currently Director of the internationally renowned Petroleum Geoscience MSc course at Imperial College London (since 2013). Gary’s research interests lie in the understanding of depositional systems and their preserved stratigraphy, and in applying this knowledge to the characterization of rocks and fluid flow in the subsurface. His research is grounded in the insights provided by outcrop geology, but he is an advocate of collaborative, cross-disciplinary research that integrates different data types and analytical approaches. Gary has published over 100 peer-reviewed technical papers, and supervised 27 PhD students (24 successfully graduated, 3 in progress).
