Description

Well logs are detailed record of the geologic formations by a borehole. These are comprehensive and important data gathered in any phase of a well’s history to identify petrophysical properties which in turn defines the economic value of a reservoir. The techniques in analysis and interpretation of well logs are therefore essential in identification of hydrocarbon recovery.

In the E&P business, integrated petroleum engineering studies and field development plans are management tools which are used to maximize economic recovery of hydrocarbons. Petrophysical engineers fulfill a key role in analyzing and interpreting subsurface reservoir data, which form the basis for reservoir models. E&P technical staff and team leaders involved in integrated studies require more than general skills in petrophysical and interpretation techniques to produce quality input to development plans.

The ICTD expert trainer will provide understanding of practical and new techniques and tools in well logging with the support of case studies. At the end of the course, participants will be able to quantitatively identify the reservoir quality, measure the storage capacity of the reservoir through integrating the reservoir and petrophysical data and to improve oil recovery.

WHY TO ATTEND THIS COURSE?

Analysis and interpretation of well logs are critical and essential to any oil & gas exploration. This course is customized specially to learn how to apply measurements and physics of well logging tools to methods for interpretation of these parameters. The understanding of techniques in analysis and interpretation as well as practice of integration of core analysis and open-hole logs will provide extensive knowledge of the topic to participants. The trainer will also provide the interpretation of cased-hole logs and recent tools for reservoir performance, production and to solve diagnostic problems. The trainer will provide information for optimum use of well logs to maximize and improved oil recovery
