Within an interactive environment and with graphical tools, the Formation Pressure (FP°) module enables analysts to
- start analysis using raw data
- display and review the quality of the pressure picks, adjusting final build up pressure, pressure drawdown, and before-and-after pressure
- use QC formula to help pick automatically the best pressure from the multiple pretests for each station.
Benefits of the Techlog FP° module include
- the ability to perform multi-well and pressure data analysis to get fluid typing from determination of densities, hydraulic zones, and free fluid levels
- a graphical interface for faster and intuitive analysis
- integration of the fluid connectivity concept: hydraulic zones defining potential reservoir regions
- a quality control input, which can be used as a weighting factor for gradient and density calculation
- defining of free fluid levels and hydraulic barriers.
The FP° module also allows analysts to investigate the uncertainties. This includes the ability to
- input uncertainty ranges for depth and pressure measurements
- estimate ranges of gradients consistent with the uncertainty model
- quantify the impact on fluid levels or connectivity of data uncertainty
- perform known gradient comparison
- conduct excess pressure analysis.
The FP° module can be used in single- or multiwell mode. It is possible to work by group (for example using hydraulically connected units) or use multi-well data to define common fluid gradients and free fluid levels between the wells.
FP° results can be combined with other Techlog modules, such as the Saturation-Height Modeling and Fluid Contact modules. This allows the user to display, cross-check, and validate contacts derived from other physical measurements. It is also possible to create and use temporary fluid contacts.
