3. When Sand Injection Calibration is selected, the following
window will appear. Two tables are on the right-hand side
which will calculate different coefficients for the calibration.
• Top table: This is used to record the three fixed sand rate
with variable flow velocity results.
• Bottom table: This is used to record the three fixed velocity
with variable sand rate results.
4.4.1 Sand noise calibration: fixed sand rate with varying flow
velocity
In this part of the calibration, it is recommended that a minimum of
three measurement points are used, following the recommendations
stated below:
• Sand rate
— Each of the injections for this test should ensure that the same
sand rate is achieved (e.g., 0.5 g/s).
• Flow velocity
— Minimum expected flow rate in operation
— Maximum expected flow rate in production
— Median expected flow rate in production
— Additional points can be taken but these should remain
between the minimum and maximum operating limits.
