breakdown of a heavier oil to a lighter hydrocarbon by bacterial action.

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.

مدت مقاومت

n: the maximum torque an induction motor will develop as load is increased, starting from full speed at no load until the motor begins to stall.

n: The voltage when emulsion begins to demulsify under the certain condition. A target used to measure stability of emulsion.

n: 1. forcing gas back into a formation by pumping into the annulus from the surface.2. any pumping procedure in which fluid is pumped into the well against pressure.

forcing fluids in the pipe into the formation at a pressure higher than the pore pressure and sometimes higher than the fracturing breakdown pressure. Used to displace a kick out of the pipe when wellbore and wellhead pressure limits permits.

n: Refers to the surfactants that cation is the active part after the surfactants breakdown in the water.

n pi: I. sediments formed by the breakdown of large rock masses by climatological processes, physical or chemical. 2. the rocks formed from these sediments.

n: Press the cylindrical core sample put between the teeterboards of compression testing machine with axial force till breakdown. Records the alternation value of stress and deflection and draw the curve and requires compressive resistance of the rock.

a small fracture treatment, without proppant, pumped into a well to assess fracture breakdown pressure, fracture extension pressure, fluid loss coefficient, frac fluid efficiency and fracture closure time.
