Heat Flow • Q – Heat Flow mW/m 2 • K – Thermal Conductivity W/m*K dd • dd - Thermal Gradient °C/km • Inverse relationship between gradient and conductivity • Heat flow is constant with depth
Heat Flow • Traditionally heat flow is determined from equilibrium temperature logs • Changes in gradient reflect changes in lithology • Thermal conductivity measured on core or cuttings • Low conductivity lithologies (shale) have high gradients and visa versa • No equilibrium logs like this in WV
