About our software of SAND_PRO:
1. Q: Rapid and realistic assessment of the sand production
potential based on minimal and easily acquired data (reservoir
properties, formation properties. fluid data and well data).
A: There are two parts in SAND_PRO for sanding potential:
empirical and quantified predictions. In the former those
empirical correlations developed by industries are collected and
provided as a estimate for sanding potential. The merits for
such a model is that the sanding potential can be predicted by
using the simple data such as sonic velocity and dynamics shear
modulus. Alternatively, more accurate sanding potential can be
forecast by either simple analytical and comprehensive solutions
with well data such as logging.
2.Q: Prediction of the onset condition of sand production as a
function of various operating condition for a pay zone interval.
A: Three major categories are defined in SAND_PRO about the
onset of sand prediction: 1) foot-by-foot pay zone sanding
prediction verse logging generated or self-design cohesive
strength profile; 2) onset of sanding prediction for a
directional well which is assumed to be drilled and producing in
any orientation against a 3D space and stress regimes; 3)onset
of sand erosion and massive skeleton sanding prediction with a
multiphase flow conditions.
In all the above mentioned options, various operational
conditions are used as changeable input, i.e. BHP, flow rate,
well orientation, temperature, sand control strategies.
