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 ...
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.
4D Seismic Assisted History Matching—Closing the Loop in Reservoir Simulation
The traditional technique of manually adjusting reservoir simulation models to achieve a history match is time consuming and problematic at best; adding 4D seismic data to the equation only increases the complexity of the task. The inclusion of 4D seismic, however, results in better constrained simulation models and a greater understanding of the uncertainty inherently associated with models.
Monitoring CO2 Injection Volumes in the Subsurface—The Sleipner Field
Subsurface CO2 injection and storage is a proven technology for keeping carbon dioxide out of the atmosphere and ...
Regional Structural Geological Modeling Through Fault Data Correlation
Onshore projects often span extensive areas, and coarse, basin-wide models are used in activities such as assessing regional stress patterns and stratigraphic trends, as well as planning rig schedules.
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.
