Reducing CO2 Emissions in Drilling Operation with 3D Mapping Technology

Abstract Kuwait reported has 89 million metric tons of CO2 emissions as per the 2020 world report published by United Nation (UN). The oil and gas sector significantly contributes to the country's economic growth while simultaneously serving as a major source of CO2 emissions. The country's national oil company has established an objective to reduce CO2 emissions in alignment with national goals. To achieve this, advancements in technology that can both minimize CO2 emissions and enhance productivity are essential. In Kuwait, the operator employed ultradeep azimuthal resistivity (UDAR) technology within a carbonate reservoir that has a production history spanning over 57 years. The primary objective of utilizing UDAR 3D reservoir mapping was to reduce unnecessary operations, such as the drilling of a pilot hole, which would otherwise consume additional energy. By eliminating these superfluous activities, the initiative aims to contribute to the minimization of carbon emissions through decreased energy consumption. The elimination of the pilot hole and the cement operation saved approximately 10 operational days per well. The rig energy saving from reduced fuel consumption amounted to approximately 230 metric tons CO2 / well. This reduction of the CO2 emissions through 3D reservoir mapping, established a new milestone and supported the nation’s goal of achieving full carbon neutrality by 2050.
