Abstract: Exploratory Applications of Log Calculated Formations Pressures and Temperatures

By

Donald J. Timko

Reasonably accurate formation pressures and temperatures can be obtained from well logs. These subsurface pressures and temperatures have an important relationship with the diagenesis of clayey sediments and the distribution types of oil and gas reservoirs. We can use these relationships along with the more conventional techniques to assist us in defining the subsurface environment as to the favorability of finding producible and commercial reservoirs in any geographical area. The application of these concepts should be considered as an additional tool of the explorationist to assist him in finding commercial oil and gas reservoirs that will become more difficult to find with more competition in future years using traditional techniques.

Several field examples and case histories will be shown to illustrate these principles.
