نمذجة PVT وضبط معادلة الحالة

في جملة واحدة

Extracts fluid study data from decades of laboratory reports and tunes the equation of state against all of it, not against the one report someone had to hand.

المشكلة

PVT reports live as scanned PDFs in a cupboard. Simulation studies typically use one or two of them because finding and digitising the rest is a week of manual work, so reservoir-wide fluid variation is ignored.

كيف تعمل

Laboratory reports are digitised through the extraction pipeline into a structured PVT repository — CCE, DL, separator tests, compositions. The equation of state is then regressed against the full set with consistency checks between samples, and samples that disagree with their neighbours are flagged for review rather than averaged away.

البيانات المطلوبة

  • Historical PVT laboratory reports, scanned or digital
  • Sampling conditions and sample validity notes
  • Reservoir temperature and pressure at the sample depth
  • Field production GOR history for cross-checking

ما الذي تحصل عليه

  • Structured PVT database with sample metadata and quality flags
  • Tuned EOS model with regression report and match quality per experiment
  • Fluid property maps showing compositional variation across the field

ما لا تستطيع فعله

Sample validity is the binding constraint, not the tuning. A large share of legacy samples were taken under conditions that make them unrepresentative, and no amount of regression fixes a bad sample. The system flags suspect samples and the honest outcome in several fields has been that a new sampling campaign is required.
