| Summary | Hydrocarbon resources have fuelled the Western-World lifestyle for around 100 years, yet global climate change threatens the prosperity, if not the survival, of mankind and many other species. A move from using the subsurface from a source of hydrocarbons to the disposal of waste CO2 (in carbon capture and storage) and energy storage is essential for the energy transition. Prospecting for old resources (oil, gas) and new (geological storage) requires a high degree of understanding of both geological and geophysical aspects of basin exploration, and particularly the interplay between these two disciplines. Subsurface exploration provides many intellectual challenges, interpreting the subsurface, based in limited (and very expensive) data to optimise resource recovery or utilisation requires a deep understanding of geology and geophysics, with prediction into data-poor areas a key skill. Fortunately, the knowledge and techniques developed for hydrocarbon exploration are transferable to the more sustainable geoenergy technologies.
The course utilises a variety of teaching methods:
Lectures and practical classes cover the petroleum system and other subsurface usage, and the application of geophysical techniques to exploration.
Interpretation of seismic reflection profiles of a sedimentary succession at the basin margin near Helmsdale using state-of-the-art digital software (Petrel) and seismic data, kindly donated by Schlumberger.
A 4 day field excursion to Helmsdale (NE Scotland) to study rocks analogous to those used in the subsurface.

Learning Outcomes
On completion of this course, the student will be able to:
Understand the geological evolution of the Inner Moray Firth - how and when rifting initiated, sedimentary facies, subsidence history including effects of fault segmentation on sediment dispersal within the basin
Perform a simple seismic interpretation using industry-standard software (PETREL) including a simple volume calculation for an oilfield or CO2 storage site.
Describe the individual components of a petroleum system for both conventional and unconventional hydrocarbon plays
Understand how the knowledge gained from hydrocarbon exploration can be applied to clener geoenergy technologies including carbon capture and storage (CCS)
Analyse and understand typical data from petroleum production, e.g. produced volumes of hydrocarbons; a traditional suite of wireline logs

Assessment details
Written Exam 50%
Coursework 50%
Assessment will consist of:
Coursework, set in Week 5, consisting of 2 essays from 4 available, to cover a reasonable range of the course material. 1 week will be allowed for the assessment. Defined word limit per essay and expectation of modest extra reading (2 - 4 references per essay). The questions will be of similar style to the exam ones, to give students experience of the format and feedback on progress. (50%)
Exam, 1 hour 30 minutes duration. 2 long-answer questions chosen from 4 options; 1 or more of the questions may have multiple sub-questions. There is no practical element to the exam e.g. no accurate plotting of graph, calculation or use of computers. No length limit to answers. (50 %)
NOTE: The exam will have questions based upon some or all of the following parts of the course:
The practical classes
The lectures
The field excursion
Assessment deadlines:
Coursework essays:
Essay A Monday week 7, 12:00 noon.
Essay B Monday week 7, 12:00 noon.
Moderation: In this course, all assessments will be moderated via Sampled Second Marking. This is a process whereby an academic member of staff, different from the marker, looks at a samples of the work to ensure consistency of marking. Where multiple markers mark the same assessment moderation also verifies that all markers are marking to the same standard.
The moderator is not double marking and cannot change individual marks. They can only make recommendations to adjust marks.

| Feedback |
Opportunities for feedback are continuous throughout the course, during the practical sessions when the lecturer and demonstrators are available. Students are able to ask for verbal feedback weekly throughout the course informally. Worked answers to practical classes are available online on LEARN, for self-assessment of work.
Each student may submit 1 written answer to any previous exam question for formative feedback, at any stage of the course.
