Answer #1

The leak off coefficient is a function of the fracture area (A), formation permeability (kf), the pressure differential between the fracturing fluid and the formation (Delta P), and the fluid characteristics.

Often, this coefficient is set as a constant throughout the treatment, which means that the fluid loss rate does not vary with pressure differential or fluid type. The effect of the formation permeability and the fluid characteristics are often combined together into a single leak off coefficient ( Ceff ). This coefficient defines the volume of fluid leaked off into the formation VL, as follows:

where, t is the time that the fracture has been open.
