an isotope tracer in a bead with the same density of the flowing fluid that is used to track fluid flow rates and therefore fluid entry and exit points along the wellbore.

n: (1) the extreme width (breadth) of the hull of a ship or mobile offshore drilling rig. (2) a walking beam. See walking beam.

n: the weights on a beam pumping unit installed on the end of the walking beam, which is opposite the end over the well. The counterbalance offsets, or balances, the weight of sucker rods and other downhole equipment installed in the well.

an artificial lift system, common to low pressure, lower rate oil wells, with a plunger type bottom hole pump operated from the surface by a rod string.

n: a machine designed specifically for sucker rod pumping. An engine or motor (prime mover) is mounted on the unit to power a rotating crank. The crank moves a horizontal member (walking beam) up and down to produce reciprocating motion. This reciprocating motion operates the pump. Compare pump jack.

n: a well whose fluid is being lifted by rods and pump actuated by a beam pumping unit.

n: a beam pumping unit that has a counterbalance weight on the walking beam.

n: a nipple or restriction placed in a line (a pipe) to reduce the rate of flow of fluid through the line. Beans are frequently placed in Christmas trees to regulate the flow of fluids corning out of the well. Also called a flow bean. See Christmas tree.

a flow restriction common in downhole chokes, surface chokes and some SSSVs.

an engineered sequence of choke settings in the start-up of a well to apply stresses in the formation in a manner that will strengthen the formation and avoid failure.
