  3. Barrel Award History • Started in 1976 by Professor Richard Selley: • Following early gas discoveries in the Southern North Sea • During early oil discoveries in the Northern & Central North Sea • Evaluation areas were based on the UKCS Exploration Licensing Rounds (1976-93): • Literature-based plus limited well and regional seismic lines • Paper-based interpretations with coloured pencils! • Strongly exploration-based (e.g. Beatrice Field discovered in the Inner Moray Firth) • 1990’s based on digital North Sea databases: • 3D seismic & well logs from proven oil & gas fields • Focused on near-field exploration (e.g. field extensions) • e.g. North Alwyn & Beryl (NNS), Argyll (CNS), Lancelot (SNS), etc. • 2000’s regional 3D seismic datasets plus digital well logs: • PC-based workstations, basin modelling & other software • Frontier &/or under-explored areas (beyond the North Sea) • Imperial Barrel Award adopted by the AAPG in 2007 as a • global exploration teaching concept (c. 80 universities • competing world-wide in 2010)

  4. Barrel Award Overview • To document the tectono-stratigraphic development of a sedimentary basin to allow a detailed assessment of its petroleum potential • To analyse the hydrocarbon prospectivity of 11 datasets from sedimentary basins in contrasting structural and stratigraphic settings: • regional to sub-regional 2D or 3D seismic dataset • 1-5 wells with wireline data • The analysis to be worked on by 11 teams of 4-5 students per team: • ca. 4 weeks evaluation time: Tuesday 22nd February – Tuesday 22nd March • The project integrates all formal teaching from both Terms 1 and 2 ranging from Seismic Interpretation to Reservoir Characterisation, and from Basin Analysis to Source Rock Evaluation • Emphasis is on exploration evaluation and basin-scale studies

  5. Rationale • New Business Opportunities (NBO) provide the growth engines for oil companies in the search for increasing their reserves base. • NBO often arise as the current operator is prepared to offer an equity stake in the acreage to another company – known as a “farm-out” opportunity. • The operator may “farm-out” for numerous reasons, e.g. (1) to dilute equity or relinquish acreage in an area considered to have low potential, (2) to acquire new, more prospective acreage, (3) to finance a drilling campaign elsewhere, (3) rationalise (‘swop’) acreage, etc. • To encourage companies to buy-in to the opportunity the operator opens up a “data room” where prospective farm-inees can view the data for a few days, assess its hydrocarbon potential and, critically, assign a value ($$$) to it. • This exercise mimics this process but with a significantly longer data viewing period than is typically encountered in the real world…

  9. Regional tectono-stratigraphic overview: essential starting point Regional Tectonic Evolution Hydrocarbon Occurrences Doust and Sumner, 2007

  10. Summary of Basin Types and Structural Styles Doust and Sumner, 2007

  11. Stratigraphic Framework Doust and Sumner, 2007

  12. Define genetic play types: reservoir/source/seals Doust and Sumner, 2007

  14. Barrel Award: Aim & Objectives • General aim: to document the tectono-stratigraphy of a sedimentary basin in order to assess its petroleum potential • Specific objectives: • Literature review to establish regional geodynamics/plate tectonics • Regional stratigraphic framework, depositional environments & palaeogeography • Basin type: classification and tectonic setting • Seismic interpretation (key horizons and associated maps) • Well log interpretation and correlation • Formation evaluation • Sequence stratigraphic analysis • Reservoir/source/seal evaluation (incl. reservoir thickness and quality maps) • Subsurface fluids and pressure regimes • Subsidence history and source rock maturation and migration (inc. 1D basin modelling) • Play fairway maps • Analysis of structural and stratigraphic traps • Prospect evaluation • Hydrocarbon volumetrics and risk assessment.

  15. Barrel Award: Methodology • The teams are in charge of their technical work and time management • The structure is less formal than Wytch Farm, partly due to the diversity of the datasets… and now you’re all more experienced! • Morning presentations on key subjects: basin modelling, petrophysics, petroleum systems, play & prospect risking, visual communication, etc. • PETROMOD basin modelling seminar (1 member per team) • Mid-week visits by senior consultants: day-long visits with individual team discussions (approx. 30 minutes per team) • Weekly review meetings with Exploration Managers (Friday pm) to monitor progress, etc. • Dry runs: comprehensive feedback on technical analysis, interpretations, presentation quality, etc.

  16. Schedule & Key Dates • Final 25 minute talk on Wednesday 23rd March to a panel of senior oil industry geoscientists • Full “dry-runs” on Friday 18th March • Technical report: summarises key structural stratigraphic and petroleum potential observations: • 20 page text limit (12 pt – 1.5 spacing) not including figures • Maximum of 10 pages additional material as appendices • Report should be clearly sectioned, bound, numbered and ready-to-read • Report handed in to Shashi Luther no later than mid-day, Tuesday 22nd March • Assessment: each team will be given a ‘team mark’ which will form part of each individual team member’s assessed coursework • Staff feedback: given at the dry-runs and after the final presentations and reports (with marks)

  17. Presentations Rules & Advice • Each team member MUST PARTICIPATE in the presentation • Each team decides who does what, but aiming for a balance among all team members • The whole class must be present from 8.45 am and in the audience by 9.00 am LATEST (no late-comers allowed in) • Staff will assess your performance based on technical quality, thoroughness, imagination, convincing arguments and enthusiasm. • Demonstrate commercial & practical awareness in your recommendations: BE REALISTIC • Questions restricted to panel members and staff • Be professional in ALL aspects of your work, appearance & presentation • Marks deducted for spelling & grammatical errors, lack of reference to data sources on slides, lack of clarity (e.g. scales!) • Edit screen shots for improved clarity (legible text, scales and scale bars, especially colour scale bars, seismic images with and without interpretation, etc.)

  18. Barrel Award Industry Panel The panel will be looking for the following: Evidence of rigorous and creative technical evaluations The ability to work to a strict deadline Effective teamwork (only the team, and not the individuals, are assessed) Sensible decision-making based on limited data Lucid, positive & enthusiastic oral presentations Each team is assessed primarily on technical quality and NOT on overall prospectivity of their area Each team member has to present and display: Competence in their particular specialist contribution to the project Awareness of the impact of their contribution on the overall project A clear understanding of the overall results of their team's effort Panel will announce 3rd, 2nd and 1st places at the end

  19. ‘Imperial Barrel Award’ at the AAPG European Section Meeting, Prague, Czech Republic, Saturday 26th March 2010 • The winning team will be sent on an all-expenses paid trip to • the above meeting, representing Imperial College (depart 25th March 2010) • Competition among other European & Russian universities, including • Moscow State University, IFP Paris, Royal Holloway • Winning team will receive a modest cash prize and tickets to another • All-expenses paid trip to the AAPG Annual Convention in Houston, USA, • on 10-13 April 2011 to compete for the international Imperial Barrel Award AAPG Europe changed the Prague date to 18th-19th March

  20. Barrel Award: the ‘Real’ Assessment • The Barrel Award constitutes part of your coursework marks • You will receive one mark per team • Marking is done exclusively by academic staff The external panel is not involved in assigning marks, only selecting the winning team on the day • Assessment is in two forms: • presentation (50%), and • report (50%) • This constitutes 20% of your total coursework marks (= 25% of the final degree mark).

  21. What do we do now? • Seismic data, well data and other available material is stored in: student-share on ic.ac.uk\group\foe\ese in the MSc PetGeo Seismic/Barrel 2011 folder. • Team folders are labelled and sub-folders can be made within your team folder to store additional collated material • It is important to delegate work tasks to each group member early in the project: • Data QC and preliminary seismic interpretation • Regional literature review • Preliminary well data analysis • …but prior to this it’s probably a good idea for all group members to look over the different datasets to form a list of “brainstormed” ideas
