Any well that does not produce oil or gas in commercial quantities. A dry hole may flow water, gas, or even oil, but not in amounts large enough to justify production.
Industry:Oil & gas
A single well that produces from two separate formations at the same time. Production from each zone is segregated by running two tubing strings with packers inside the single string of production casing, or by running one tubing string with a packer through one zone while the other is produced through the annulus. In a miniaturised dual completion, two separate casing strings are run and cemented in the same wellbore.
Industry:Oil & gas
A hole that is not in gauge; that is, it is smaller or larger than the diameter of the bit used to drill it.
Industry:Oil & gas
A well control device, usually installed above the ram preventers, that forms a seal in the annular space between the pipe and well bore or, if no pipe is present, over the well bore itself.
Industry:Oil & gas
A bailing device with a release valve, usually of the disc or flapper type, used to place, or spot, material (such as cement slurry) at the bottom of the well.
Industry:Oil & gas
The space around a pipe in a well bore, sometimes termed the annular space.
API-monagram adj; the logo of the American Petroleum Institute (API) that is placed on certain pieces of oilfield equipment by the equipment manufacturer. API licences the use of the monogram on equipment that meets the API's minimum standards. It offers publications regarding standards, recommended practices, and other industry related information.
Industry:Oil & gas
Supports the electrical cables that feed the power from the control panel to the rig motors.
Industry:Oil & gas
On diesel electric rigs, diesel engines drive electric generators. The generators produce electricity that flow throw cables to electric switches and control equipment enclosed in a control cabinet or panel. Electricity is fed to electric motors via the panel.
Industry:Oil & gas
A fishing tool that is attached to tubing or drill pipe and lowered over the outside wall of pipe or sucker rods lost or stuck in the wellbore. A friction device in the overshot, usually either a basket or a spiral grapple, firmly grips the pipe, allowing the fish to be pulled from the hole.
