Course Coordinator: Dr Ulrike Schacht
This course comprises 2 components: (I) Evaluating reservoirs, seals and pay (II) Resources & Reserves.
The frist part provides participants with a working knowledge of the main techniques (qualitative and quantitative), used by Reservoir (Development and Production) geologists to evaluate subsurface properties of hydrocarbon reservoirs. Geological controls on well log signatures porosity, permeability, relative permeability, and capillarity are discussed. Case histories review conventional methods of determination of net pay and demonstrate some improved techniques using data from core, sidewall core, cuttings, conventional plug measurements (porosity and permeability) in conjunction with capillary pressure data. The course focus will be on conceptual understanding and practical applications using case studies and hands-on exercises.
The second part of the course explains strength and weaknesses of various resource estimating methodologies, explains the differences between resource estimates used for regulatory reporting and those used for business decision making. The course explains differences between resources and reserves and different regulatory and fiscal regimes. Exploration and development views are covered, as are deterministic, scenario and probabilistic methods, with the aim of gaining a thorough understanding of various resource categories. The meaning of proved, proved plus probable, and proved plus probable plus possible reserves are explained. Alternative estimation methods, such as volumetrics, material balance and decline curve analysis are discussed. An appreciation will be gained of data limitations and uncertainty and how this is reflected in final resource volumes. Class exercises will work through a resource assessment from data collection to field performance assessment.

Learning Outcomes
Course Learning Outcomes
On successful completion of this course students will be able to:
1 Explain the integration of basic petrographic, wireline and capillary pressure data to evaluate reservoir rock quality, pay vs. non-pay, 2 Differentiate between reservoir fluid contacts (eg Oil / Water contacts) and Free Water Level (FWL), 3 Explain expected fluid saturations at different levels of the reservoir, and determine thickness of the transition zone. 4 Evaluate seal capacity (thickness of hydrocarbon column a seal can hold before it leaks 5 Use 2-way capillary pressure analyses to approximate recovery efficiency during primary or secondary recovery, 6 Use resources and reserves terminology and methodologies, which have now been internationally standardised 7 Explain the importance of uncertainty in reserves estimation and to become familiar with various estimation techniques to quantify uncertainty; to address uncertainty, probabilistic methods (as distinct from deterministic methods) are now generally advocated and these are being taught 8 Discuss the importance of good reserves management for optimising the value of petroleum developments and how such management (or the lack of good management) may impact companies commercially 9 Use @Risk in dealing with statistics, distributions and probabilistic reserves calculations; some exercises will be conducted in groups, which are subsequently disseminated to the entire class, similar to work situations in the industry 10 Recognise that resource and reserves estimates utilise data from all subsurface disciplines, requiring close cooperation among disciplines
The above course learning outcomes are aligned with the Engineers Australia .

Assessment
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

Student Feedback
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.
Communication
It is important that all students maintain active communication channels throughout the year. The primary communication channels to students in this course are as follows.
MyUni: Students should regularly check the MyUni website (http://myuni.adelaide.edu.au/).
Email: Each student should regularly check his or her University-provided email account (firstname.lastname@student.adelaide.edu.au) for information from members of the academic staff concerning course work matters and other announcements as they arise. Make sure you clean up your Inbox regularly as if it is full you will not receive our email! We will regard an email message being sent to your student email address or an announcement posted on the MyUni site as our having communicated with each member of the class. Not reading one’s University provided email or MyUni announcements will not be a valid excuse for missing important deadlines etc. -

Fraud Awareness
Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student鈥檚 disciplinary procedures.
