n: 1. a failure of equipment.2. in a fracture treatment or a squeeze job, the failure of formation rock to withstand pressure, allowing it to rupture. adj: pertaining to the amount of pressure needed at the wellhead to rupture the formation in a fracture treatment or a squeeze job (as in formation breakdown pressure).

fracture.

n: a new mode used to compute the formation breakdown pressure and propose by detection logging corpration in America

n: a mechanism of formation breakdown used to study how to form interconnecting between the relief well and the gasser with
decrepitation method

formation breakdown pressure,. The pressure at which the fracture initiates.

n: die fracturing of a formation from excessive borehole pressure.

n: refer to formation fracturing

initiating a fracture in the formation.

n: the pressure at which a formation will fracture. formation competency n: the ability of the formation to withstand applied pressure. Also called formation integrity.

n: the forcing of cement slurry into a well at the point to be sealed with a final pressure equal to or greater than the formation breakdown pressure. See squeeze cementing.

n: fracture the formation with pressure and inject cement into formation untill the formation pressure keeps at certain specially designated value

n: a device that pem1its cement to be displaced in stages at two or more points above the bottom of the string. Instead of all the cement being pumped out the bottom, a stage tool allows some of the cement to be pumped out at several points above the bottom. Used in cases in which a long column of cement might cause formation breakdown if the cement were displaced from the bottom of the string.
