This study on fluid displacement using invasion percolation with capped extraction wells shows reduced early production stops. Adding extraction wells is more effective when more fluid has already been recovered, aiding oil exploration strategies.

Area of Science:

  • Physics
  • Geophysics
  • Chemical Engineering

Background:

  • Fluid displacement dynamics are crucial in resource extraction, like oil exploration.
  • The invasion percolation model simplifies complex fluid-interface interactions.
  • Understanding mass distribution aids in optimizing extraction efficiency.

Purpose of the Study:

  • To analyze mass distribution in a viscous fluid displacement model with multiple extraction wells.
  • To investigate the impact of capped extraction wells (zero pressure) on production.
  • To evaluate the efficiency of adding extra extraction wells for enhanced fluid recovery.

Main Methods:

  • Application of the invasion percolation model on a square lattice.
  • Simulation of fluid displacement with one injection well and four surrounding extraction wells.

Related Experiment Videos

  • Analysis of mass distribution under zero extraction well pressure conditions.

    • Main Results:

    • The probability of stopping production with small amounts of displaced mass is significantly reduced.
    • The effectiveness of adding an extra extraction well depends on the cumulative recovered mass.
    • The study identifies distinct universality classes for mass distribution based on displacement criteria.

    Conclusions:

    • Capping extraction wells at zero pressure (Pe=0) alters production dynamics, reducing premature stops.
    • Strategic addition of extraction wells, based on prior recovery, can enhance overall fluid yield.
    • Findings offer insights for optimizing fluid recovery strategies in oil exploration.
