Detailed Well Analysis

The analytic modeling allows the user to quickly review many wells and get a general understanding of the major drivers of a play. At this point, the user will understand what some of the geological properties look like and will have gained a broad spectrum of petrophysical parameters to work within. The user can arrive at a wide range of probabilistic forecasts based on these physical parameters by having compared (analyzed) basic well properties. So is there any way to narrow the range of forecasted recoveries the analytic model offers? The answer is yes…with more detailed modeling.

Concurrent with Limits analysis and modeling, the user can perform very detailed well analysis with the numerical well modeling software, Resolve™. This will help reduce the uncertainty of the physical parameters in the analytical model and work towards a more unique solution by utilizing the field testing that has been performed (microseismic, core studies, downhole gauge readings, etc.). Resolve offers finite element modeling technology that is capable of solving more complex problems by investigating interactions beyond the scope of a simpler analytics-based package.

OR can help answer questions like:

• What kinds of fractures are present in the well? (Planar vs. Complex)
• How many stages in the well are producing? (Designed vs. Actual)
• How effective is the completion?
• What is the total well drainage area likely to be?
• What is the ideal fracture spacing?
• What is the ideal well spacing?
• What is the impact on performance of a naturally-fractured reservoir?
• What is the effect of inter-well fracture communication?

By determining the most likely causes of performance issues of a well, or conversely, why some wells are so highly productive, the user can reduce the uncertainty in the analytic models, produce more accurate probabilistic forecasts, and suggest best practices for future wells specific to the play. Any fracture shaping or other studies performed and subsequent conclusions made for the selected wells are then fed back into Limits and the ORKA system to further reduce forecast uncertainties for all of the studied wells.
