Multiwell Retrospective Testing is a PolyGon software aided workflow based on the correlation between bottomhole pressure and flowrates history. It uses a multi-well pressure deconvolution technique to estimate the potential drainage volumes, boundary types and their proximity, reservoir transmissibility and cross-well connectivity. It reconstructs the history of formation pressure and productivity index.
It provides a lot of constraints for future reservoir modelling. It also helps to identify wells with suboptimal performance and propose a relevant surveillance.
APPLICATIONS
Production Enhancement
- Locating priority zones for the new wells and side-tracks
- Selecting priority candidates for workovers (water shut-off, stimulation, fracturing)
- Optimize production targets
- Identifying the best candidates for converting to injection
Reservoir Study
- Assessing the length and orientation of hydraulic fractures
- Identifying the presence of spontaneous fractures
- Assessing fault conductivity
- Localizing the barriers and pinch outs
- Calibrating shale breaks
- Quantification of the cross-well interference
- Quantification of reservoir properties in cross-well interval
- Quantification of reservoir properties in near-well area
- Reconstructing the history of formation pressure and productivity index
- Adjusting the random mistakes in flow rate history records
Advantages
- No field operations and no production deferment
- Reconstruction of formation pressure and productivity index history
- Reconstruction of cross-well interference history
- Immunity to random mistakes in rate history records
- Immunity to random mistakes in rate history records
