Abstract

The optimal location of drilling the wells. in the oil and surrounding application
has caused a significant economical impact on the reservoir management. The wells
location issue in a productive formation is a vital aspect in order to have an effective .
field development. However, the determination of the optimal wells location in the
specific geographical locations is a challenging matter since it depends on the
geological and the fluid properties, reservoir characteristics and as well as on the
economic parameters. Hence, reservoir simulation is recognized as one of the most .
reliable tools for defining the optimum strategy of production. Nevertheless, using the
simulation approach in doing the forecasting bears the risk of uncertainty in the input
data. Due to the reservoir inhomogeneity and the uncertainty in the reservoir description,
solution to the problem is impossible at the intuitive level. Using the conventional
approach to define the number of production wells and its locations is a costly trial and
error process as the outcome is fully depends on the ability of the reservoir engineer to
understand the reservoir behavior and its operational limits. Thus, an alternative
approach in optimizing the well location which is by determining the high productivity
zone within the reservoir where the hydrocarbon production is expected to reach the
maximum field production. It is performed by evaluating each. of the possible well
position at different locations and defining the sensitivity of several reservoir properties
which will have the significant impact to the optimum well placement. The. studied was
carried out on an actual Malaysia reservoir model which is the Gelama Merah field
located in offshore Sabab. By utilizing the Eclipse lOO - A black oil model simulator
software, several studies have been made and the predicted values of production were
significantly promising. Furthermore, it was found that the. optimal well production
duration is a function of well spacing with respect to the number of production well
drilled. Apart from that, changing of oil saturation (So) will always contribute to the
high impact for the optimal well placement and oil productivity. Hence, the method
proposed could be one of the useful tool to assist the progress in the decision making for
the field development and strikes towards the optimal and effective hydrocarbon
recovery.
