Formation pore pressure abnormalities can be detected and evaluated by many known methods. These abnormalities may be identified by drilling parameters, formation log properties, mud analyses, etc. The natural gamma ray intensity, a formation property, can also be used for pressure detection and evaluation. Using the Measurements Whilee Drilling Gamma Ray Log, pore pressure can be interpreted at the well-site, thus providing a real-time pressure detection tool for better well control. The gamma ray intensity, a natural radioactive property, has not been used as a primary pore pressure indicator; this paper provides a technique to use this formation property as a pore pressure detection tool. Analyses, primarily from the Gulf Coast, were made from both Measurements While Drilling and wireline gamma ray logs, demonstrating the flexibility of this method.
