| Abstract | Cost overruns can easily manifest during well construction due to unexpected drilling problem issues including lost circulation and stuck pipe. Too often the best drilling practices used to address trouble zones are limited to a few conventional methods with a narrow range of effectiveness. In that purpose, the asset management drilling tools and techniques introduced in this study can be effectively deployed in the analysis of drilling performance. They help to detect new opportunities, quantify and address removable lost time and analyze the major problems in a comprehensively and structured manner. The aim of this paper is to evaluate the Non Productive Time occurred during drilling operation in a geothermal exploration well in Indonesia. |
