2.5.7. Leak-Off Test

Task is used to estimate fracture gradient using leak-off test parameters.

Input Values
	Mud Weight	Density of the mud
	Test TVD	True vertical depth of casing shoe
	Surface Pressure	Surface pressure when formation is broken and drilling fluid permeate into formation
Results
	Fracture Gradient	The gradient needed to initiate a fracture
