An optimal completions programme depends on predicting and controlling sand production to minimise risk and maximise hydrocarbon production.


Depletion, excessive drawdown, a change in production conditions (well shut-in, water hammer and cross flow), or water breakthrough can all lead to sudden or unexpected sand production. Sanding can give rise to excessive sand erosion of production equipment together with handling and disposal of significant volumes of dirty sand. This can lead to the abandonment of the well or casing collapse.


By establishing critical limits to your production parameters under different depletion and drawdown combinations, the GeoScience sanding assessment enables you to optimise completions, well head equipment and production schedules.
