CO2 Huff and Puff Injection Operation Overview in Jatibarang Field Lessons Learned from a Successful Case Study in Mature Oil Field

Abstract The objective of this paper is to provide an overview of the CO2 Huff and Puff injection operation in the mature Jatibarang field, Indonesia, and share the lessons learned from a successful case study. The scope of this paper includes the project preparation, implementation, and troubleshooting. The aim is to provide insights into the key factors that contributed to the success of the project and to identify potential challenges and their solutions. The paper will present a comprehensive review of the CO2 Huff and Puff injection process, start from the design of the injection plan and the monitoring and evaluation of the injection process. The methods, procedures, and process used in the project will be discussed, including the selection of candidate wells, the injectivity test, the CO2 injection rate, and the well performance evaluation. The paper will also highlight the challenges faced during the implementation of the project and the solutions adopted. The results of the CO2 Huff and Puff injection operation in the Jatibarang field are promising, with an oil production rate increase of up to 86% with minimum operational difficulties. The successful implementation of CO2 Huff and Puff injection operation in Jatibarang Field was mainly attributed to the good operation procedure that prioritized safety and efficiency. With careful planning and intensive discussion conducted to identify potential risks and minimize operational difficulties, the operation was able to run smoothly, with minimal issues and zero HSE incidents. One of the key challenges that CO2 injection operations usually face is the risk of pipe blockage due to CO2 freezing. Fortunately, no such incidents occurred during the operation. Continuous monitoring of the injection process and fluid properties managed to ensure that the CO2 remained in gas phase in surface and supercritical state in the bottom hole throughout the operation. In conclusion, the success of the CO2 Huff and Puff injection operation in Jatibarang Field was due to the careful preparation and execution of a well-designed operation procedure. The operation demonstrated that with the right approach, the potential risks and challenges associated with the project can be mitigated. This paper will present novel information on the implementation of CO2 Huff and Puff injection in a mature oil field in Indonesia. The lessons learned and the best practices identified in this project can be of benefit to the petroleum industry, particularly for those dealing with mature oil fields. The paper will also provide insights into the design of the injection plan and the monitoring and evaluation of the injection process, which can be useful for future CO2 Huff and Puff injection projects.
