n: a special wire mesh installed in a shale shaker that allows liquid mud to pass through hit traps die cuttings and larger solid particles the mud carries from the hole. Often, more than one screen is installed in the shale shaker;also, the screens are usually vibrated to help remove die cuttings and solids on top of die screen.

n: A kind of relative standard that represent the stability of shale.

n: A small pit, typically located immediately after the shaker screens, which is used as a settling pit to separate coarser solids that accidentally bypass the shakers. Mud enters the pit at one side and exits via an overflow at the other. Sand traps are dum

n: the termination of a shale bed. shale shaker n: a vibrating screen used to remove cuttings from the circulating fluid in rotary drilling operations. The size of the openings in the screen should be selected carefully to be the smallest size possible to allow 100 percent flow of the fluid. Also called a shaker.

n: natural gas deposit located near enough to die surface that a conductor or surface hole will penetrate the gasbearing formations. Shallow gas is potentially dangerous because, if encountered while drilling, the well usually cannot be shut in to control it Instead, the flow of gas must be diverted. See diverter.

n: The exploration well that explorating the formation on the top of the given producing pay.

n: The thread section on the top of the bit,which be used to join the drill string.

n: a relatively small container of high explosive that is loaded into a perforating gun. On detonation, the charge releases a small, high-velocity stream of particles (a jet) that penetrates the casing, cement, and formation. See perforating gun.

n: An explosive device that utilizes a cavity-effect explosive reaction to generate a high-pressure, high-velocity jet that creates a perforation tunnel. The shape of the explosive material and powdered metal lining determine the shape of the jet and perform

a shaped explosive charge for perforating steel pipe.

n: The bomb be made of the energy-gathered powder.
