Forward Seismic Modeling in a North Sea Reservoir
Improved, flexible and faster access to critical data is vital for fully informed decision making in today’s multidisciplinary asset development teams. It is also imperative to include the highest fidelity quantitative temporal data when building reservoir models to improve development plans and maximize returns on investment.
Oil Reservoir Compaction; Risk Reduction for Drilling Infill Wells
During production, North Sea chalk reservoirs are commonly prone to severe compaction due to reduction in pore pressure—this increases the load on the rock matrix, resulting in compaction. In some extreme cases the result is seabed subsidence on the order of 10 meters. This magnitude of subsidence causes challenges to the existing production infrastructure, including the integrity of the drilled wells, and leads to geomechanical changes in the subsurface which can impact seismic travel times.
Flight Planning and Route Analysis Via 4D Scene Building
The state-of-the-art CoViz 4D software from Dynamic Graphics is extremely powerful for data ingestion/integration, and quantitative spatiotemporal visualization across multiple data types. These unique capabilities are already leveraged by users across many disciplines and industries. Recently DGI has also been focusing on aerospace / military applications, with particular attention to 4D scene building and route / flight planning.
Infill Drilling Placement using Conditional Seismic Attribute Filtering
Infill drilling aims to tap previously undrained reserves in a mature hydrocarbon field. By definition, infilling happens later in field life and hence involves the analysis of greater volumes and a greater diversity of a priori data. Furthermore, the economics of infill drilling can be marginal. Therefore, a rigorous quantitative decision-making process is necessary to justify the economic risk required to implement drilling and production plans.
