fuite de fluide de fracturation

CONT: During the hydraulic fracturing process, some of the fracturing fluid may leave the fracture and enter the targeted formation adjacent to the created fracture (i.e. untreated formation). This phenomenon is known as fluid leak-off. The fluid flows into the micropore or pore spaces of the formation or into existing natural fractures in the formation or into small fractures opened and propagated into the formation by the pressure in the induced fracture.
