THE APPLICATION AND THE IMPACT OF NEW STANDARDIZED AND REFINED SEQUENCE STRATIGRAPHY CORRELATION IN WEST BARAM DELTA: CASE STUDY OF X FIELD

The understanding of sequence stratigraphy study is used as a chronostratigraphic framework for the correlation and mapping of sedimentary facies and for stratigraphic prediction (Emery et. al., 2005). The idea of a new approach of refined sequence stratigraphy for West Baram Delta (WBD) came considering of current reservoir correlations within the fields in WBD are done mainly based on lithology correlation. In addition, the unstandardized zonation throughout the fields in WBD contributes to discrepancy in static and dynamic modeling. The new standardized stratigraphic framework is built by integrating 3D seismic megamerged volume, well logs, and biostratigraphic data. In order to get the full impact and to add value to the new invention, a detailed study in field scale need to be done. Therefore, this study will focus on X field where the application of the new standardized and refined sequence stratigraphy is discussed. Technically, the refined stratigraphy and new reservoir scheme are utilized for better reservoir delineation and prediction in order to explore and develop the remaining upside potential within each stratigraphie unit, and to capture the bypass oil. The study has indicated a presence of an upside potential where it will be discussed in detailed in this paper.
