The user can check the influence of planned oil production strategies on the amount of expected sand, and thus tailor both draw-down and depletion scenarios so as to minimise sand production during the whole expected life of the reservoir.
SandPredictor uses a semi-empirical sand production model developed in the Sand Production JIP. The model is a combination of analytical borehole stress calculation together with correlations developed from extensive hollow-cylinder sand production laboratory tests; these correlation factors predict the stress for onset of sand and the mass of produced sand as a function of stress state and fluid flow rate.
The SandPredictor System consists of the following elements:
- User-friendly interface
- Calculates sand production based on intended draw-down and assumed depletion field history
- Allows reservoir properties’ input parameters from log
- Suggests default sand onset stress from SINTEF correlations, or user defined ones
- Calculation for either open-hole or perforated well
- Any well inclination allowed
- Wealth of possible data in plotting options
