a detonating cap between two detonating cords in a series of perforating guns.

a pump located along the length of a pipeline to raise the pressure and overcome friction or elevation losses.

n: an installation on a pipeline that maintains or increases pressure of the fluid corning through the pipeline and being sent on to the next station or terminal.

n: usually a small pump mounted upstream of anod1er pump that charges the fluid being pumped prior to the fluids reaching the main pump.

n: 1. a tubular device placed in a vertical position, either inside or outside a larger vessel, and through which well fluids are conducted before they enter the larger vessel. A boot aids in the separation of gas from wet oil. Also called a flume or conductor pipe. 2. a large pipe connected to a process tank to provide a static head that can absorb surges of fluid from the process tank. Also called surge column.

n: a device made up in the drill stem above the mill to collect bits of junk ground away during a milling operation. During milling, drilling mud under high pressure forces bits of junk up the narrow space between the boot sub and hole wall. When the junk reaches the wider annulus above the boot sub and pressure drops slightly, the junk falls into the boot sub. A boot sub also can be run above the bit during routine drilling to collect small pieces of junk that may damage the bit or interfere with its operation. Also called a junk sub or junk boot.

a device run in the drill string just above the mill to catch cuttings.

abbr: blowout preventer.

blow out preventer.
