Innovative Pathways to Decarbonisation Through Advancing Emission Reduction Technology

Abstract BR Cluster facilities have historically recorded peak total greenhouse gas (GHG) emissions of ~1.1 million tons CO2e in 2019. A higher power consumption and large routine flaring are the biggest contributors in GHG emissions. This paper describes an effective integrated pathways undertaken through decarbonization roadmap, Flaring Abatement Initiatives and Energy Efficiency Initiatives to reduce the GHG emission footprints. These initiatives and roadmap contribute towards a greener hydrocarbon industry and helps in combating climate change. BR cluster has identified an innovative pathway to achieve 50% emission reduction by 2030 and Net Zero Emissions by 2050 by utilizing numbers of technologies and initiatives to reduce GHG emissions. Wide ranging initiatives are identified and deployed with help of new technologies includes flare reduction, flare gas recovery for power generation, facilities and Water Reservoir Management (WRM) energy efficiency improvements, novel solution for water treatment and nature-based solutions for carbon abatement. A novel solution for flare Gas reduction is achieved with help of new technologies (flare gas recovery for power generation, and upgrade of control) to recover routine flaring volumes and phased out Fuel gas consumption. As a result of the deployed technologies and initiatives, BR facilities recently achieved ∼64% reduction in flaring and overall ∼42% drop in GHG emissions. This significant reduction achieved by divert the flare gas from Early Development Field projects to power generation for field operations. From 2030 onwards, all routine flaring will be eliminated as gas is used for power generation. Several initiatives were implemented across the cluster to improve surface and subsurface equipment reliability/energy efficiency, includes export pump trimming, control valve modification, stop recycling, solar ESP, Electrical Submersible Progressing Cavity Pump Permanent Magnetic Motor (ESPCP PMM) and conversion gas lift to ESP. These implemented initiatives have contributed to GHG emission reduction by 642 ktCO2e. A novel solution for water treatment and disposal was executed in R field to utilize and phase-out the disposed water produced from Rima station to utilizing the water for agriculture and wildlife protection and saves the environment from GHG emissions associated to Deep water Disposal (DWD) power consumption. The reduction achieved in power consumption is 5.1 MW, with a reduction in GHG emissions of more than 86 ktCO2e. In line with the decarbonization pathway, total GHG emission is predicted to further reduce and reach 423 ktCO2e (60% lower) by 2030 and 200 ktCO2e (82% lower) by 2044. This paper shows Innovative pathways to decarbonization by implementing advance emission reduction Technologies that’s help to achieve cluster emission goals for energy efficiency and emissions reduction. BR cluster decarbonization pathway, learnings and approach could be replicated elsewhere in the Hydrocarbon industry thereby contributing to a cleaner energy for the planet.
