Fluid density | ρl=ρ0(1+α(PT−P0T)−β(T−T0)) | *α*, *β*, P0T and *T*_{0} are constants. |

Fluid viscosity | μ=μ0e−δ1(T−T0) | *T*_{0}, *μ*_{0} and *δ*_{1} are constants. |

Average thermal conductivity of the rock and fluid | Γa=φΓl+(1−φ)Γs | The thermal conductivity of the rock, Γ_{s} and the liquid Γ_{l}, are both assumed constants. |

Average heat capacity of the rock and fluid | (ρc)a=φρlcl+(1−φ)ρscs | Where the rock density *ρ*_{s}, and the specific heat capacities for the rock and the fluid (i.e. *c*_{s}, *c*_{l}, respectively) are assumed to be constant. |

Liquid suction | Ψ=−Pcap | Where *P*_{cap} is the capillary pressure given as: *P*_{cap} = *P*_{a} – *P*^{T}. Here, *P*_{a} is the air pressure (assumed atmospheric) and *P*^{T} is the total pressure (in the liquid phase). |
