1.
A basic component of the sucker rod pump that serves to draw well fluids into the pump.
2.
The rod that serves as a piston in a reciprocating pump.
3.
The device in a fuel-injection unit that regulates the amount of fuel pumped on each stroke.
A bradenhead pack; no packer, very limited pack pressure capability.
See poor boy.
A fluid moving as a unit in which all shear stress occurs at the pipe wall and hole wall.
The stream thus assumes the shape of several telescopic layers of fluid with lowest velocities near the pipe and hole walls and the fastest in the middle.
An absolute flow property indicating the flow resistance of certain types of fluids.
It is a measure of shearing stress.
The topmost portion of a string of sucker rods.
It is used for lifting fluid by the rod-pumping method.
It has a uniform diameter and is smoothly polished to seal pressure effectively in the stuffing box attached to the top of the well.
The percentage that the volume of the pore space bears to the total bulk volume.
The pore space determines the amount of space available for storage of fluids.

An immobile offshore structure from which development wells are drilled and produced.
Platform rigs may be built of steel or concrete and may be either rigid or compliant.
Rigid platform rigs, which rest on the seafloor, are the caisson-type platform, the concrete gravity platform, and the steel-jacket platform.
Compliant platform rigs, which are used in deeper waters and yield to water and wind movements are the guyed-tower platform and the tension-leg platform.
1.
A sucker rod, shorter than usual, used to make up a sucker rod string of desired length.
Pony rods are usually placed just below the polished rod.
2.
The rod joined to the connecting rod and piston rod in a mud pump

(nautical) to install anchors behind each other in tandem
Height of drilling mud in the pits
1.
The male section of a tool joint.
2.
On a bit, the bit shank.
3.
One of the pegs that are fitted on each side into the link plates (side bars) of a chain link of roller chain and that serve as the stable members onto which bushings are press-fitted and around which rollers move.
