SAND_PRO is software designed for sand control during completion, sand prediction, and critical BHP and production COMPUTING.
Sand production is a phenomenon occurred during production induced by the in-situ stress concentration near a wellbore and perforation tips in poorly cemented formations. Such a solid production compromises oil production, reduces the life cycles of both the down hole and the surface equipment. In an extreme situation, the whole well can be lost as it can be flooded by sand. The sand problem is particularly critical in off-shore production.
SAND_PRO, coupling multiphase flow with the formation skeleton deformation, can be used to calculate both stability and production conditions before and after sand control strategies are implemented. Regardless of well type, SAND_PRO can be used.
For those oil/gas reservoirs, SAND_PRO may be used to determine if a well can be operated continuously for production based on the stage of sand production.
To those production wells with no sand, SAND_PRO can be used to predict when and if sand production is problematic in the future and when production increase is desired.
To those wells in which sand control is necessary, SAND_PRO can be used before the field implementation, to evaluate the safety and reliability of the method, and optimizing the method by considering the production reduction.
To a reservoir which is prone to sand before any production, SAND_PRO can be used to design a corresponding completion strategy, which can assist us to evaluate the total production and sand control cost.
To those wells which are extremely sensitive to sanding, i.e. horizontal wells and off-shore wells, SAND_PRO can be used to calculate the cumulative amount of sand production, so that one may be able to determine if and when sand control strategy must be implemented. This allows us to minimize the completion costs.
Following outputs can be generated using SAND_PRO :
- Field method for sanding prediction
- Geomechanics data evaluation though logging data
- Geomechanics data evaluation through experimental data
- Critical bottom hole pressure
- Critical drawdown
- Critical wellbore temperature
- Optimized perforation strategy
- Cumulative sand production
- Pore pressure and stresses COMPUTING
