Abstract

The Logging While Drilling (LWD) calibration is one of the fundamental controls to ensure reliable formation evaluation data in an oil and gas drilling. There are many different calibration types in logging tools, one of them is density-neutron calibration. A study case conducted in one oilfield service company (Company A) showed that density-neutron calibration for nuclear logging tool takes longer time and impose more safety hazards compared to the other LWD tool calibrations. The purpose of this research is to figure out the possible improvement of calibration process to increase the efficiency and to reduce the safety hazards especially for radiation. The method of this research used DMAIC approach which the data was taken from Company A for calibration period during 2020–2022. Based on the research, a new automation system is designed and constructed in calibration area to enable remote assisted calibration. This new system consists of railway structure, pneumatic system, and PLC based automation system. The result of this study based on cost-benefit analysis showed that a new process of remote assisted density-neutron calibration will significantly reduce health and safety risks by reducing 67% of radiation dose, improving efficiency by eliminating 30% of total calibration time and reducing man-hours by 55%, also increase the calibration success rate by lowering failed calibration from 23% to only 10%. In all, this brings big impact on company operational cost by saving 19k USD annually.
