Fieldwork in the Petroleum System of the Wessex Basin
Our Petroleum Systems of the Wessex Basin field course provides you with the opportunity to look at all aspects of a petroleum system within the vicinity of the Wytch Farm oil field and amongst some of the most dramatic scenary of the British coastline. Most of this field trip takes place along the Jurassic Coast, a UNESCO World Heritage site, and focuses on the development of the Wytch Farm oil field in an Area of Outstanding Natural Beauty
Did you know?The Wytch Farm oil field is Europe's largest onshore oil field. Extended reach horizontal drilling was pioneered in this field in order to minimise its environmental footprint around the Poole Harbour area.
More about the Wessex Basin
During the Triassic, the Wessex Basin was largely a desert, but by the Jurassic sea level had risen such that sandstones, mudstones and limestones were deposited in shallow to moderately deep water. Changes in water depth and sediment input gave rise to optimal conditions for the deposition of organi rich mudstones (potential source rocks) interbedded with sandstones and limestones that were capable of hosting oil reserves. Later tectonic movements then led to faulting and folding that facilitated the development of traps and seals for hydrocarbon.
