كيف تُحسب

  • Straight-line PI: q = J(P̄ − Pwf), valid while the whole drainage area stays above the bubble point.
  • Vogel: q/qmax = 1 − 0.2(Pwf/P̄) − 0.8(Pwf/P̄)², for a saturated reservoir.
  • Composite: a straight line above the bubble point and Vogel below it, joined at qb = J(P̄ − Pb) so the curve and its slope are continuous.
  • J is back-calculated from the test point under the model you choose, not assumed.

أين تتوقف عن الصحة

One test point fixes one constant, so the shape of the curve is entirely the model you picked — two models through the same test point can differ by thirty per cent at high drawdown. It is also a snapshot: reservoir pressure falls with depletion, skin changes with every job, and an IPR built on a test from last year describes last year. Multi-rate tests exist precisely because a single point cannot distinguish between a low PI and a high one with turbulence.
