n: 1. the process of lowering the drill stem into the wellbore when the well is shut in on a kick and when the weight of the drill stem is sufficient to overcome the force of well pressure. 2. the process of putting tubing into a well under pressure.

v: shutting in and stripping in when well blowout .

v: The stripping operation achieved by reverse switch of preventer when there has high pressure in the hole.

n: the simultaneous pulling of rods and tubing when the sucker rod pump or rods are frozen in the tubing string.

n: 1. the process of raising the drill stem out of the wellbore when the well is shut in on a kick. 2. the process of removing tubing from the well under pressure.

abbr: streaks;used in drilling reports.

n: In a sucker-rod pump, one complete round of the polished rod (surface stroke). On each stroke, a fixed volume of liquid is lifted. This volume is related to the cross-sectional area of the pump and the length of the stroke.

n: a mechanical percussion tool that can deliver either upward or downward impact. See jar.

the number of rod strokes per minute of the beam ift unit. Set by depth, viscosity of fluid, gas content, weight of fluid supported, etc.

the number of strokes that a mud pump makes in one minute. SPM times time times pumper chamber volume equals volume displaced. Can be compared to volume recovered.

n: Used to fish the fragments in the hole,which is made by permanent magnet.
