تحسين حقن الغاز الرافع

Fit a gas-lift performance curve through your injection tests and find both the technical peak and the point where the next MSCF stops paying for itself.

Per barrel, net of what you would rather not discuss.

Per MSCF — compression, fuel and opportunity cost.

كيف تُحسب

  • q_oil = a + b·ln(q_inj) + c·ln(q_inj)², fitted by least squares from the 3×3 normal equations.
  • The technical optimum is the turning point, exp(−b/2c), where the slope reaches zero.
  • The economic optimum is where dq_oil/dq_inj equals gas cost divided by oil price — always at a lower injection rate than the technical peak.
  • Available gas, if you set it, caps the recommendation.

أين تتوقف عن الصحة

A performance curve fitted from field tests is only valid at the conditions those tests were run in. Raise the separator pressure, cut the water or deepen the injection point and the curve moves. It also assumes the well is stable at every rate, which gas-lifted wells frequently are not — a well heading between two states will give two different rates at the same injection and both will be recorded as tests.
