Horizontal Well PI Comparison

Description

Compare horizontal well productivity index calculations using different correlations. Useful for understanding the sensitivity of PI estimates to the chosen method.

Methods:

  • Joshi (1988): Most commonly used, assumes ellipsoidal drainage
  • Borisov (1964): Early USSR work, simpler formulation
  • Giger-Reiss-Jourdan (1984): French approach, considers anisotropy
  • Renard-Dupuy (1991): Improved treatment of vertical permeability
  • Economides (1994): Unified model for rectangular drainage, full 3D anisotropy

Flow Regime Comparison

Compare well productivity under different flow regimes: pseudosteady state (bounded reservoir), steady state (constant pressure boundary), and transient (infinite-acting). Understanding flow regime impacts is essential for accurate production forecasting.

Productivity Index Calculation

Calculate well productivity index (PI) and understand the impact of skin damage. Also shows drainage radius and effective wellbore radius calculations.

Gas Well Deliverability

Gas well deliverability analysis comparing Darcy flow (low rate) with non-Darcy flow that includes turbulence effects at high rates. The non-Darcy coefficient D accounts for inertial resistance near the wellbore.

Vogel IPR Curve

Construct an IPR curve using the Vogel correlation for solution-gas-drive reservoirs producing below bubble point. Shows the characteristic concave-downward shape of two-phase flow.

Fetkovich IPR Curve

Construct an IPR curve using the Fetkovich backpressure equation. This empirical method works for both single-phase and two-phase flow by fitting well test data to Qo = C(Pr² - Pwf²)ⁿ.

Klins-Clark Modified Vogel IPR

Construct an IPR curve using the Klins-Clark (1993) modified Vogel equation. This correlation improves on the original Vogel method by introducing a pressure-dependent exponent d that accounts for the ratio of reservoir pressure to bubble point pressure.
