Applied Well Log Interpretation
Candidates: Geologists, geophysicists, reservoir and petroleum engineers who wants to improve their skills to interpret different open-hole logs and use them to characterize, model and manage their reservoirs. Attendees must have a basic knowledge on logs.
Summary: Logs provide valuable data to identify and describe the formations crossed by the borehole. The main goal of this course is to get the attendees familiar with the objectives, design features, advantages, disadvantages, limitations and applications of the logs and associated logging tools. This workshop will provide intensive hands on training on the concept and response of logging tools. Participant will develop an appreciation for the limitations and constrains of the borehole environment on the validity of the recorded log data.

Candidates: Geoscientists, petrophysicists, reservoir engineers and research and development staff who want to gain fundamental insight into the capillary properties and hydrocarbon distribution in reservoir rocks.
Summary: This course provided a detailed knowledge of how capillarity affects hydrocarbon distribution in a reservoir rock, and how the magnitude of capillary forces can be used to deduce valuable information about sizes of pore throats and the geometry and volume of the pore network. The integration of the capillary pressure data with other geological, petrophysical and engineering data in modeling reservoir properties will be highlighted.

- Integration of Capillary data in reservoir description and modeling
Candidates: Petrophysicists, petroleum and reservoir engineers, production engineers, drilling engineers, technical supervisors and those interested in understanding the use of cased-hole logs.
Summary: This course explains what cased-hole surveys and production logs can provide and what they can’t, about what is happening in and around the well; including cement bond quality and reservoir isolation; completion and casing integrity and production/ injection flow profile. Each logging tool principles, response, measurements and analyses are treated separately.
Course Contents:
