Fracture gradient definition

Fracture gradient means the overburden gradient that is standardized as 22.6 kPa/metre (1.0 psig/foot) of depth.

Fracture gradient means the pressure gradient, measured in pounds per square inch per feet, that, if applied to a subsurface formation, will cause that formation to physically fracture.

Fracture gradient means the ratio of pressure per unit of depth, measured in pounds per square inch per foot, that if applied to a subsurface formation would cause the formation to physically fracture.
