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

On April 9, 2019, IATMI and SKK Migas, together, held a technical discussion in Jakarta. The role of reservoir management on maximizing the economic return of asset became 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 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 which was dissimilar one and 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 every reservoir management. As the first speaker, Bambang Ismanto (British Petroleum Asia Pacific) said that reservoir management became 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 up the integrated reservoir management needs three parameters: reservoir characterization, field development and depletion plan, and reservoir surveillance and optimization plan.  She also shared her experience on monitoring 15 to 20 wells annually, and the data would assist her on 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 lenses shaped of the reservoir and spotted. 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 to map the reservoir was essential on the decision making regarding its reservoir management.
