The act of boring a hole (1) to determine whether minerals are present in commercially recoverable quantities and (2) to accomplish production of the minerals (including drilling to inject fluids). [..]

The use of such a machine to create holes for exploration or for loading with explosives.

Piercing of stacks of papers in a precision manner with round hollow drills at high speeds. Loose-leaf notebook paper is an example of drilled paper.

A three-barreled long gun in which a combination of smoothbore and rifled barrels is used.

The using of a rig and crew for the drilling, suspension, completion, production testing, capping, plugging and abandoning, deepening, plugging back, sidetracking, redrilling or reconditioning of a well (except routine cleanout and pump or rod pulling operations) or the converting of a well to a source, injection, observation, or producing well, an [..]

  The process of using a multi-point tool to penetrate the surface of a workpiece and make a round hole.  dry run

A process that is used to generate a round hole in the surface of a part using a multi-point tool.

The act of creating a hole using a drill bit

(n) the act of drilling(n) the act of drilling a hole in the earth in the hope of producing petroleum

The handling or switching of cars in freight yards.

The process of boring a hole into the ground using special equipment. Drilling is used in exploration to collect direct data about the subsurface, locate hydrocarbons and survey aquifers. It is also u [..]

Drilling is a Machining process in which a cylindrical or cone-shaped tool (drill in drill chuck, drill head on drilling bar) executes a rotary Cutting motion and a progressive feed in the direction o [..]

Core: a drilling method that uses a rotating barrel and an annular-shaped, diamond impregnated rock-cutting bit to produce cylindrical rock cores and lift such cores to the surface, where they may be collected, examined and assayed. Reverse circulation: a drilling method that uses a rotating cutting bit within a double-walled drill pipe and produce [..]

Piercing a hole in rock. In exploration, drilling allows for samples of the rock to be taken. In mining, it is used to insert explosives for blasting.

"Drilling" includes drilling, redrilling and deepening of a geothermal well.

The act of boring into the earth.

The act of boring a hole through which oil or gas may be produced if encountered in commercial quantities.

Directional drilling is the intentional deviation of a well bore from the vertical. Although well bores are normally drilled vertically, it is sometimes necessary or advantageous to drill at an angle from the vertical. Controlled directional drilling makes it possible to reach subsurface areas laterally remote from the point where the bit enters th [..]

A modern directional-drilling technique using mud motors to begin a well, drilling vertically then diverting the bore hole a few degrees from vertical every 50 to 100 feet (angle building) until the well bore is horizontal. The procedure is very effective in producing from thin but porous and permeable formations. To produce from the long axis of a [..]

A procedure for drilling at an angle from the vertical by means of special downhole drilling tools to guide the drill assembly in the desired direction. Slant holes are drilled to reach a formation or reservoir under land that cannot be drilled on, such as beneath a town site, a water supply lake, a cemetery, or industrial property wehre direct, on [..]

is a main well construction process including well boring, casing columns installation, and producing formation testing.
