A Novel Workflow for Modeling Complex Compartmentalized Structures Leads to Enhanced Field Development Strategy

Abstract

Reservoir compartmentalization, whether structural or stratigraphic, is one of the most prominent parameter for accurately characterizing the distribution of hydrocarbons in the subsurface and it is a key element for optimizing hydrocarbon recovery. In order to accurately characterize its compartmentalization, a new volume-based structural modeling technique have been applied for generating a geocellular model of the complex, highly faulted east flank of the studied field (Sabah, Malyasia). Benefits over existing pillar-based and surface-based techniques are discussed.

The volume-based modeling technique consists of interpolating a continuous 3D property representing the relative stratigraphic age of the formations from all available well and seismic interpretation data. A watertight structural framework composed of faults and horizon surfaces is then extracted from this property, and converted to a geocellular grid in which the faults are stair-stepped. New workflows were developed for early integration of fluid distribution and production data during the creation of the geological framework, leading to an accurate delineation of fault compartments.
