The asset
A mature oilfield discovered in 1967, characterized by thick sedimentary deposits and complex tectonic structure. The field contains almost all the fluid types from black oil to volatile oil and gas condensate. The reservoir comprises of complex heterogeneous, unconsolidated and consolidated sandstone, where permeability varies from few milli-Darcy to multi-Darcy level as reservoir depth deepens. A highly complex geological structure—due to its “flower-shaped” faulting system—has led to unfavorable water movement and arduous well placement in heterogeneous layers.
In total, nine distinct reservoirs were included in the program of work. The ability to model the reservoirs with their complexity—considering the range of uncertainty and running simulations in an acceptable timeframe—was critical to understand the subsurface, evaluate risk and optimize the FDP. Dynamic models only existed for some of the reservoirs in scope, composed through time-consuming manual workflows and long simulations that ran into days using existing on-premises infrastructure. No dynamic modelling was available for the deeper, more complex reservoirs, and Dragon Oil was unable to optimize the infill drilling locations and the waterflood and gas-injection plan.
Leveraging the potential of cloud computing and AI capability, SLB deployed the Agile Reservoir Modeling solution enriched with RE Data Science & Innovation through the Delfi digital platform, to improve and accelerate the different modeling steps, find new opportunities and optimize FDP workflows at scale.
