SAND_PRO is a software designed for sand control during completion, sand
prediction, and critical BHP and production COMPUTING
s.
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 compromising oil production,
reduces the life cycles of down hole and surface equipment. In the 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 for comparisons.
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
