 Rationale of Scenario •  New Business Opportunities (NBO) provide the growth engines for oil Rationale of Scenario • 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 your 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, 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 and assess its hydrocarbon potential. • This exercise mimicks this process but over a timeframe significantly longer than typically encountered in the real world…

 Assessment •  Final 30 minute talk (Friday 31 st March) to a panel of Assessment • Final 30 minute talk (Friday 31 st March) to a panel of senior oil industry geoscientists: preceded by talk “dry-runs” on Monday 20 th March • Talk will be assessed on technical quality, thoroughness, imagination, convincing arguments and enthusiasm. • Talk should be supported by a short (1 page) handout summarising key findings of the study – similar in format to Wytch Farm handouts. • Each team will be given a mark which will form part of each individual team member’s assessed coursework. • Executive report which summarises key structural stratigraphic and petroleum potential observations • 20 page limit (12 pt – 1. 5 spaced text) not including figures • Maximum of 10 pages additional material as appendices • Report should be clearly sectioned, bound, numbered and ready-to-read

 What do we do now?  •  Get to know the Data Package: Seismic What do we do now? • Get to know the Data Package: Seismic data, well data and other available material • It is suggested that the team organize a data system to store additional collated material alogn with those in the data package. • 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 • … after looking over the data, “brainstormed” ideas

 DATA ROOM VISIT CHECK LIST This list attempts to assign certain tasks to the respective DATA ROOM VISIT CHECK LIST This list attempts to assign certain tasks to the respective disciplines when attending data rooms, but it should be recognized that some of the ŌtasksÕ may require cross- discipline investigation. Some general questions that the Team should address while considering or attending any data rooms are as follows: 1. What has worked well, and not, in this basin/region? 2. What has been the exploration strategy in the area? 3. Is there any new technology that can be applied to this area to enhance chance of geologic and commercial success? 4. What could be done differently that would improve success in this venture/proposal? 5. What are the key petroleum system elements of this opportunity and what data are required to accurately represent this opportunity to management? Is there a source rock and a vbiab; e reservoir? 6. What data havenÕt they shown you that may be available? 7. Why is this opportunity available now? 8. Do we have the right people on this data room visit to accurately obtain/evaluate subject data? 9. Has a confidentiality agreement been signed and does it conflict with other potential Kufpec operations/projects? 10. What hard data are currently in-house and what is needed to improve our understanding of the opportunity? 11. What has changed to improve the economics (better infrastructure, new laws and fiscal terms, new discoveries, etc? ) 12. Is a translator necessary for presentations and/or data review? Who will provide any translations, if necessary? 13. Are we looking for oil or gas? Is this the appropriate basin to explore for oil or gas? 14. Which are the possible scenerios? Are there existing pipelines? What is their ullage? Is there any spare capacity and what is it? 15. Are there any possible drilling problems in this area (e. g. shallow gas, overpressures, ice, jungle, mountains, hurricanes, etc. )?
