Common Risk Segment Mapping for Cuttings Reinjection
Drilling scenarios such as infill drilling, water flood optimization, cuttings reinjection and CO2 injection often require an in-depth study of a field to determine the optimal drilling location within a set of restrictions. Quantifying the decision making around the process requires the integration of dozens of diverse datasets, often containing dynamic information and spanning a range of realizations.
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.
Fracture Propagation Analysis from Inter-well Tracer and Microseismic Data
Following an inter-well tracer study for their field, an onshore group was given the results of the study in the format of spreadsheets and 2D charts. The spreadsheet data were particularly difficult to interpret and the group felt a 3D/4D visualization of the tracer results was critical to fully understand them. Furthermore, the group wanted to integrate the tracer data with other field data that could potentially help with the tracer interpretation, including offset well trajectories, well logs, property models, microseismic data and horizon surfaces.
Advanced 3D Well Planning for Improved Wellbore Collision Avoidance
Planning a trajectory can be challenging in an open field, but when a drilling facility has dozens of existing ...
InSAR Data Analysis of the Belridge Field
Interferometric Synthetic Aperture Radar (InSAR) is a powerful remote sensing technique that produces a very detailed picture of the shape of the ground surface. The data returned are so precise that they can reveal changes in the elevation of the earth down to the level of millimeters per day, enabling very small changes in surface elevations to be quickly discovered, which can be critical to land management.
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.
