Topic : "Integrated Reservoir Modeling and Flow Simulation Study: Can the Mature Oil Field take Benefit from It?"

As the national oil company, Pertamina operates numerous mature oil fields throughout Indonesia. These are the fields that have been operated for significantly long period of time. Most of them are still operated under primary depletion. Plan for Enhance Oil Recovery (EOR) through secondary recovery and/or tertiary recovery have been or being considered for increasing the oil and gas production from such fields.   Integrated Reservoir Modeling followed by Flow Simulation Study has been used as a standard practice within the oil industry to build Field Development Plan (FDP). This technique shows significant superiority compared to the traditional reservoir engineering analysis that does not consider the presence of heterogeneity in the reservoir. The use of this technique is especially interesting for the relatively newer fields because data availability. Without doubt, the technique produces significant added value by reconciling various data from multi‐disciplinary information. Additionally, the technique also provides the possibility to quantify uncertainties which is inherent with any sub‐surface data and modelling process.   This presentation attempts to demonstrate the benefit of the Integrated Approach for mature oil field with minimum data. In this case, the main challenge will be how to smartly build the model using the available information. One consequence for using this approach for the mature field is the need to evaluate the uncertainty efficiently.   As an illustration, we will present a general workflow for conducting Integrated Reservoir Modeling and Flow Simulation Study supported by some examples. The workflow includes the standard process for building static model, dynamic ranking for multiple realization models based on Streamlines Simulation or Fast Marching Method (FMM), efficient upscaling, history matching, and future prediction. The focus will be on how to capture various uncertainties. Additionally, we will also present a procedure that may be used to optimize well placement quickly for simultaneous plan of primary and secondary recovery process. Our ultimate objectively is to demonstrate that the mature oil field should also take benefit of the recent development of Integrated Modeling approach.

Biography of the Speaker:

Dr. Asnul Bahar is Principal Consultant on Reservoir Modeling at Kelkar and Associates, Inc., based in Tulsa, OK (USA), since 1997. His specialization is in the area of Integrated Reservoir Modeling and Flow Simulation study. He has performed numerous full field studies for worldwide clients. These works have put him as the team leader in integrating data from geological, geophysical, petrophysical, and engineering disciplines, to come up with the representative reservoir models used for building full field development plan. Using his special skill in computer programming, he is also in-charged for developing and maintaining PETREL Plug-ins, computer software based on OCEAN Platform. Early in his career, Dr. Bahar worked as Field Engineer for Schlumberger Wireline & Testing that gave him the taste for international working environment. As part of his duty, Dr. Bahar is also active as the instructor in providing industrial short training classes organized by Schlumberger-NExT and Petroskills for worldwide clients With the international exposure, Dr. Bahar has adapted to various working condition, developed high communication skills, and quickly learn for new challenges. Dr. Bahar earns his B.S degree, in 1988, in Mechanical Engineering from Institut Teknologi Bandung, Indonesia, M.S degree in 1995 and Ph.D degree in 1997, both in Petroleum Engineering from the University of Tulsa, OK (USA).
