Parameter | Value | Description |
---|---|---|

sizeX | Length size of the reservoir drainage box. X-direction, parallel to the well, [ft] | |

sizeY | Width size of the reservoir drainage box. Y-direction, perpendicular to the well, [ft] | |

sizeZ | Reservoir height. Z-direction, [ft] | |

Kx | Horizontal permeability in X-direction, [mD] | |

Ky | Horizontal permeability in Y-direction, [mD] | |

Kz | Vertical permeability, [mD] | |

L | Length of the horizontal part of the well, [ft] | |

Rw | Wellbore radius, [ft] | |

Bl | Liquid formation volume factor, [bbl/STB]. | |

Ul | Liquid viscosity, [cP] | |

S | Skin factor, [dimensionless] | |

x1 | X location of the heel of the well. For the centrally placed well is equal to 0.5*(boxLength-wellLength), [ft] | |

y0 | Y location of the heel of the well. For the centrally placed well is equal to 0.5*boxWidth, [ft] | |

z0 | Z location of the heel of the well. For the centrally placed well is equal to 0.5*reservoirHeight, [ft] | |
