n: the horizontal direction of a formation bed or fault plane as measured at a right angle to the dip.

the compass direction of a feature such as a flood plane or fault.

n: an extra piece of metal placed on the bottom of an oil storage tank to protect it from the repeated striking of the plumb bob at the end of the gaugers tape.

n: horizontal displacement along a fault plane. The San Andreas fault in California is a strike-slip fault.

a tectonically induced failure of a section of a formation with the result that one block of the formation moves horizontally to the formation.

n: a spot on the bottom of a storage tank or on the datum plate that is directly below the reference point on the hatch. This location is where the innage bob comes to rest when the tank is gauged and serves as the zero point for all innage measurements.

n: the entire length of casing. tubing. sucker rods. or drill pipe run into a hole.

n: The entire length of casing ,tubing ,or drill pipe run into a hole .

a mill that cuts to the side, opening up windows or cutting out restrictions.

n: an explosive method utilizing Primacord. which is an instantaneous textilecovered fuse with a core of very high explosive. It is used to create an explosive jar inside stuck drill pipe or tubing so that the pipe may be backed off at the joint immediately above where it is stuck.

n: An explosive line which ,when detonated ,imparts concussion to pipe causing it to unscrew or back-off.Also called Prima-Cord.

one to four strands of explosive detonating cord suspended by wireline in a well and exploded to “rattle” the pipe and drop scale and debris from the sides of the pipe. Used frequently in back-off operations (unscrewing a pipe joint downhole).

v: to thread the drilling line through the sheaves of the crown block and traveling block. One end of the line is secured to the hoisting drum and the other to the derrick substructure.
