School of Engineering and Technology, (SET)

The course provides both basic and advanced knowledge on well logging and formation evaluation, including Quicklook Log, Full and Advanced Interpretation. The course also deals with new types of logging such as FMI and NMR as well as the special types of formation such fractured basement. The course is designed in such a way that the staffs from oil and gas company, who need to update the knowledge on well logging and formation evaluation techniques to work in a subsurface team, can attend it as traing course in relatively short period.

Review on basics of well logging: logging types, terminology, logging contracts, preparation of a logging program; coring, well mud logging; Quicklook Log interpetation: basic quality control, identifying the reservoir, identifying the fluid and contact, calculating porosity and hydrocarnon saturation, permeability determination; Full intepretation: net sand definition, porosity calculation, Archie saturation, permability; Advanced interpretation tecniques: Saturtion/height analysis, shaly sand analysis, carbonate, fractured granite, multi-mineral/statistical models, FMI, NMR, thermal decay neutron interpretation, ANN and Fuzzy logic; Production geology and reservoir engineering issues.

The course is offered during the summer inter-semester, when some staffs from the industry would join in as a training course. Experts from industry may be invited to give lectures on some customized topics. The students will attend the continuous lectures in a relatively short period at the beginning of the course and are guided to work on a project of well logging interpretation and formation evaluation. The project report will be submitted and presented at the end of the course, when a final exam is also taken.

The final grade will be computed according to the following weight distribution: 

Homework, Project Work & Presentation (50%)
Final Exam (50%).

Closed-book exam.
