Figure 1. Bambang Ismanto presented his experience on reservoir management in IATMI Technical Discussion.

On 9 April 2019, IATMI and SKK Migas, held a technical discussion in Jakarta. The role of reservoir management on maximizing the economic return of asset was the theme of technical discussion. This event was attended by several experts, practitioners and academics in the oil and gas industry. As the keynote speaker, Wahju Wibowo (SKK Migas) highlighted that the collaboration of every unit was important to minimize the operational cost and maximize the oil recovery. He also underlined the uniqueness of every reservoir management that each was different from the other, so that risk assessment and risk management must be done correctly.

Three speakers were invited to share their strategy on reservoir management, considering the uniqueness of each reservoir management. As the first speaker, Bambang Ismanto (British Petroleum Asia Pacific) said that reservoir management had become important based on the decision that had to be made on a certain time. He also emphasized that the important success factor in reservoir management was solid leadership. As the second speaker, Sri Intan Wirya (Exxon Mobil Cepu Ltd) shared her experience in managing the reservoir of Cepu Block. She pointed out that the integrated reservoir management needed three parameters: reservoir characterization and field development depletion plan and also reservoir surveillance and optimization plan.  She also shared her experience on monitoring 15 to 20 wells annually as the data would assist on her decision making regarding its reservoir management.

As the final speaker, Andre Wijanarko (Pertamina Hulu Sanga Sanga) explained the strategy on managing a challenging reservoir. The complexity of the reservoir was characterized by the lense-shaped reservoirs spotted at the field. However, the reservoir had a good economic value, so it needed to be explored. He asserted that the understanding of the reservoir and the use of grid-based in mapping the reservoir was essential on the decision making process regarding the reservoir management.
