| Abstract |
Effective management of geothermal well drilling requires proper collection, analysis and presentation of drilling data from the on-set to the completion and testing of the well. The interpretation and evaluation of all available information regarding geology, structure, geophysics, flow paths, temperature and surface conditions is done by an interdisciplinary team consisting of geologists, physicists, geochemists, reservoir scientists, drilling engineers who work together on a common platform as opposed to each discipline developing their own ideas independently. The integrated information and data collected from actual drilling operations can then be applied in the optimization of the drilling process resulting in improvements and consequently better well being drilled. During the actual well drilling, the record of activities, the bottom hole assembly (BHA), casing, drilling fluids and other materials, directional information and other aspects of drilling must be recorded on a regular basis. These information helps in the operations analysis and performance of various drilling aspects. This paper gives an outline of the reporting and reports generated during the well drilling process and uses RIMDrill software, which is a rig to office drilling information system for drilling contractors (Infostat, 2012), to store and analyse well data with the aim of using the information in optimizing the drilling processes. The Daily Reports data are entered at the rig site and transferred to a central office where data is consolidated for the entire rig fleet. The program defines the major time and cost areas and provides critical information for accounting purposes and in optimizing the drilling processes. It also supports analysis for management and for operational decision making which can significantly impact the drilling process, cost and time. |
