This integrated course and field workshop offers an optimum environment to build fundamental knowledge of petroleum geology and hands-on experience of using subsurface data, whilst reinforcing concepts with daily visits to world-class outcrops along the Yorkshire coast, used for decades by oil companies as analogues for the North Sea. This workshop develops both knowledge and in-depth understanding.
The course reviews the fundamental elements of petroleum geoscience. The key elements of a petroleum system are reviewed; source rocks, reservoirs (including unconventional reservoirs), traps, seals and the timing of generation relative to trap formation. Emphasis is placed on the integration with typical oilfield data. Visits to outcrops reinforce the lectures and allow the participants to understand the lithologies and characteristics of key surfaces and reservoirs / seal architecture. The Jurassic sequences exposed along the Yorkshire coast offer a unique opportunity to observe many of the elements of the North Sea petroleum system.
The course examines subsurface environments, the usage and display of typical subsurface geological data, with an introduction to wireline logs. This is then developed into a definition of petroleum systems and an introduction to play fairway definition and finally leads / prospects.
We conclude with the assessment of subsurface resources by calculating in-place reserves using deterministic methods.
Planned Field Visits
Saltwick Nab to examine the well exposed Lower Jurassic mudstones on the coast. Here we will look at the key criteria for depositing a source rock and its quantification of richness and maturity. A field experiment will generate hydrocarbons in the field to reinforce the theory!
Staithes to examine shallow marine reservoirs exposed along the beach. At this locality we will look at how depositional environments can be determined from the rock properties and examine the controls of reservoir quality, heterogeneity and faulting
Cloughton to examine Middle Jurassic fluvial reservoirs
Whitby to look at reservoir architecture and controls on reservoir development
Course Level: Foundation Duration: 5 days Instructor: Jonathan Redfern
Designed for you, if you are...
A new hire graduate geologist, geophysicist or an engineer with limited experience of geoscience
Some basic geological knowledge is assumed, but no prior experience of oilfield data or techniques used to interpret these datasets.
How we build your confidence
Each day comprises intensive lectures and practical activities, reinforced by field visits to examine outcrops in some classic locations along the Yorkshire coast, so as to observe typical source rocks, seals, reservoirs and structures
The field visits help you understand what your subsurface data is measuring and reinforce the lectures
The outcrops visited expose direct analogues of the North Sea Petroleum Systems and give hands-on experience of some of the lithologies and recognition of the defining characteristics from pore to reservoir unit scale
Group projects are undertaken to recognise key criteria of depositional environments and the controls these have on reservoir source seal and trap
