Today's rigsite information acquisition systems are demanding to the operator, costly to install and maintain and hardly friendly to inter-company networking interests. Cost-efficient solutions, integrating rigsite instrumentation with drilling data acquisition through sensor telemetry, daily drilling reporting and all additional related information services /e.g. cement job records, well logs, well tests etc.) are clearly wanted by the drilling community to enhance quality control. The paper lists experiences gained with extensive drilling rig instrumentation and drilling process information gathering systems over a period of 12 months, critically evaluating the quality and usefulness of commonly acquired drilling data as well as the actual application of such information volumes in accelerating the drilling learning curve and enhancing process and quality control. A detailed description of storing "streamed" drilling data into a large-scale multi-user relational database and the additional value of such information volumes available to the user "at his fingertips" is presented. The realization potential of such systems on low-to medium-cost on-shore drilling operations as well as the possible integration of multi-well and multi-rig systems and the buildup of field- and area-databases are presented from a service-company as well as operator standpoint. A definition of the current state-of-the-art in rigsite information management is attempted and the future potential for such systems is assessed.
