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.
Well Location Optimization with Visual and Quantitative Analysis

Well Location Optimization with Visual and Quantitative Analysis

An onshore team was tasked with producing a list of potential well landing locations based on attributes in a geological model. Four pad locations in the field were each given a set of 12 wells arranged in a radial pattern; the model’s potential target area covered a Z range of about 1650 ft. The well landing locations needed to be optimized to hit the model’s high Net to Gross (NTG) and Gamma Ray (GRD) areas because these two attributes had high confidence amongst the team. Finally, the potential well path landing options had to be easily visually ranked.
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.
Reservoir Pressure Anomalies: Investigating Causes with CoViz 4D

Reservoir Pressure Anomalies: Investigating Causes with CoViz 4D

In a California onshore field, with hundreds of closely-spaced production and injection wells, a horizontal production well was experiencing occasional dangerously high pressure and temperature spikes – leading to a serious health and safety issue.
A Relief Well Planning Case Study

A Relief Well Planning Case Study

In the Gulf of Mexico, a drilling trajectory needed adjusting due to a recent update to the reservoir model. Although the change to the trajectory was minor, the shift of the placement of the 14-inch and 11 7/8-inch casing shoes invalidated the previously designed relief well plans. With a fast-approaching deadline for drilling operations, the well planning team had little time to make a new relief well plan that could (1) achieve the objectives of the updated target plan, (2) meet industry-standard relief-well design constraints, and (3) be ready to send for permitting.
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.
