Geophysical evaluation of some oil prospects in Arabian Gulf region

Abstract

The main task of this study is focusing on the Arabian gulf and some comparative logs with other locations all over the world. It shows the traditional applications ofWireline logging and the new techniques of the logging while drilling, how to compare, and to how :fur it can replace the Wireline logging.

Since the introduction oflogging while drilling (LWD) in 1989, operations in more than

400 wells worldwide have propelled the technology through the first stage of maturation. Tools have improved, interpretation methods can address more complex problems, and challenges presented by highly deviated and horizontal wells are being overcome.

In this study, some light is focused on the tool types, physics, and purposes, also some comparisons between the traditional Wireline logs and the new LWD technique logs to predict the future of these tools and how they are competent and challenging.

Formation evaluation and interpreta on methods depend upon the log analysis, which is the most important value for the client to be able to measure the reservoir reserve, the well age, the drive mechanisms, the formation pore pressure and a lot of other parameters that directly affect the oil and gas production.
