Well-information systems as applied to geopressured reservoir description

The purpose of this paper is to present a brief discussion of contemporary well-information systems. Equipment and procedures useful for geopressured reservoir description are emphasized. Efficient execution of a proposed drilling operation begins with preplanning. The well information systems to be employed depend upon the cost and complexity of the operation. If abnormal pressures are anticipated, equipment and techniques have been developed for monitoring instantaneous indicators and drilling trends. The occurrence of pressure can be detected with sufficient accuracy to ensure safe and economical operation. Reservoir data accumulated during the drilling operation can be beneficial to both drilling and reservoir engineers. These data can be made available in the form of tables and logs. Computer-generated data can be stored for later processing. (6 figs., 2 tabs., 8 refs.
