Cost-Effective Facilities Design Approach with Sustainability Field Development Plan Towards Achieving Net Zero Carbon Emission

With the current market fluctuations trend outlook, it is severely more challenging to prove the viability of the major greenfield oil and gas field development. Various key factors in the design are identified to be able to contribute to effectiveness of the facilities concept towards achieving fit of purpose design in terms of cost, safety, and reliability. It is paramount deep dive on this study due to the facilities that mostly contributes 50% of the overall development cost and has significant impact on the project economics. Since offshore greenfield developments the cost are generally high, hence, It is paramount for the Field Development Team to find a balance between Facilities cost with strategy to design for GHG emission reduction. Since new upstream project are required to comply with zero flaring & zero venting approach, it is crucial for the project to develop surface facilities to capture the GHG emission in any one of the options i.e., Gas Disposal, Gas Injection for Reservoir Pressure Maintenance or team can also consider any Carbon Abatement Technology. Surface facility is designed to filter the CO2 in the hydrocarbon production at offshore CPP (Central Processing Platform) and re-inject the CO2 back into the formation via a dedicated gas injector well. The selection & optimization of surface equipment CO2 are of critical in ensuring that project will still be economical despite with additional cost invested to reinject the CO2 back into the reservoir. This paper would provide more insight into the study and analysis to be considered during designing new facilities development in a field with high CO2 that integrate development wells producing hydrocarbon and lesson learnt and best practices that are valuable for future project with similar scope. This paper goes beyond mere exposition and meticulously details the established process flow, deftly managed to effectively guide the Field Development Plan (FDP) team in formulating the most cost-effective development concept. This concept not only aligns with the company's aspirations for a sustainable field development plan towards achieving net-zero carbon emissions but also promises positive economic outcomes. Within these pages, the team not only narrates but vividly demonstrates a meticulously selected case or concept deemed as the most cost-effective among all the iterations evaluated. This chosen facilities concept doesn't stand in isolation; rather, it serves as a beacon, illuminating the pathway for other greenfield projects grappling with similar challenges in their fields—be it high contaminants or waxy crudes. It exemplifies the practical realization of an economical and sustainable Field Development Plan, harmoniously meeting the company's ambition of net-zero carbon emissions while ensuring positive economic projections. The insights shared within this paper are poised to resonate with and inspire a broader spectrum of projects facing comparable challenges, fostering a paradigm shift towards more sustainable and economically sound field development practices.
