n: A kind of jet perforator that can be retrivabled after be used.

n: a packer that can be pulled out of the well when it fails, to be repaired or replaced.

n: A type of packer that is run and retrieved on a running string or production string, unlike a permanent production packer that is set in the casing or liner before the production string is run. Retrievable packers are most commonly used in well interventi

a non-permanent packer meant to be retrieved.

a tool used to locate, equalize and retrieve a plug or orther settable downhole device.

condensate that precipitates in the pore space of the rock in a previously dry gas (single phase) reservoir as the pressure drops below the dew point. The building condensate severely reduces the permeability to gas.

n: in reservoir mechanics, the formation of liquid droplets in a gas as the well is produced and the pressure drops. Some hydrocarbons exist naturally above their critical temperature in the reservoir;as a result, when pressure is decreased, instead of expanding to form a gas, they condense to form a liquid.

n: see retrograde reservoir.

n: a reservoir in which the pressure is high and the hydrocarbon content is completely in a gaseous or supercritical phase at initial conditions. As the pressure drops because of production, the heavier hydrocarbon components condense, forming liquids within the reservoir. Such action is the retrograde phenomenon. If the reservoir pressure is completely depleted, only a small portion of these liquids will revaporize and be recovered.

n: a U-shaped section of piping that connects two other pipes parallel to each other.

the comparison of permeability after testing with the additive compared to initial permeability.

n pi: the mud, cuttings, and so forth, that circulate up the hole to the surface.

n: Mud that comes back to the surface and exits through the flowline after being pumped down the drillpipe. Lost returns is the situation in which some or all of the Mud does not come back to the surface, which indicates that mud is being lost into weak, f

fluids and solids flowing out of a well during circulating.
