في جملة واحدة

Decides which wells will produce sand and sizes the gravel and screen for the ones that will.

المشكلة

Sand production erodes chokes and flowlines and eventually kills the well. Sand control is expensive enough that installing it everywhere is not viable, so the prediction of which wells need it carries real money.

كيف تعمل

Sanding potential is predicted from rock strength derived from sonic logs, drawdown history and depletion state. For wells that need control, gravel size and screen aperture are designed against the measured particle-size distribution using standard Saucier and Coberly criteria, with the full sensitivity shown rather than a single recommended size.

البيانات المطلوبة

  • Sonic and density logs for mechanical property estimation
  • Particle-size distribution from sieve or laser analysis of formation samples
  • Drawdown and depletion history
  • Sand production history and failure records from offset wells

ما الذي تحصل عليه

  • Sanding risk per well and per interval with critical drawdown
  • Gravel size and screen aperture design with the governing criterion named
  • Completion recommendation: open hole, cased and perforated, or screen type

ما لا تستطيع فعله

The particle-size distribution is the controlling input, and a distribution measured on a drilled cutting or a poorly preserved core sample is not representative of the formation. Where no reliable PSD exists the design falls back to conservative field analogues, which is a more expensive completion than the well may need, and we say so explicitly rather than presenting it as an optimum.
