في جملة واحدة

Tunes the reservoir model until it reproduces what the field actually produced, automatically and with the uncertainty kept rather than discarded.

المشكلة

Manual history matching takes three to six months per field and produces a single "matched" model whose uncertainty has been argued away rather than quantified. Decisions are then made as if that one model were the truth.

كيف تعمل

An ensemble smoother with multiple data assimilation updates the property ensemble against production history, keeping a family of matched models rather than collapsing to one. Parameter groups are constrained to geologically plausible ranges agreed with the geomodeller before the run.

البيانات المطلوبة

  • Simulation model with a defined uncertain-parameter set
  • Clean production and injection history by well, with allocation quality flagged
  • Pressure surveys and well test results with dates
  • Geological constraints on each uncertain parameter

ما الذي تحصل عليه

  • Ensemble of matched models with posterior parameter distributions
  • Match quality by well and by phase, with the poorly matched wells named
  • Forecast bands rather than a single deterministic forecast

ما لا تستطيع فعله

The method assimilates the data it is given, so allocation error in the production history becomes a property of the matched model. In fields with back-allocated rates and no well-test discipline the result is a model that matches wrong numbers precisely. We run a data-quality gate first and have refused this work where the gate failed.
