Oil Reservoir Compaction; Risk Reduction for Drilling Infill Wells

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.
Infill Drilling Placement using Conditional Seismic Attribute Filtering

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.
Fracture Propagation Analysis from Inter-well Tracer and Microseismic Data

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.

Oil and Gas Collision Avoidance: Well Planning in 3D

Planning a trajectory can be challenging in an open field, but when a drilling facility has dozens of existing ...
Common Risk Segment Mapping for Cuttings Reinjection

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

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.
