TERM DEFINITION
Vent A normally sealed mechanism which allows for the controlled escape of gases
from within a cell.
VGA Video Graphic Array.
Virtual Memory A method of making disk storage appear like RAM memory to the CPU, thus
allowing programs that need more RAM memory than is installed to run in the
system. This technique is slow compared to "real" memory.
Viscosity The inherent resistance of a substance to flow.
VOG Velocity of Gas.
Volatile Memory A storage medium that loses all data when power is removed.
Volt The unit of voltage or potential difference.. One thousand volts = 1kV.
Voltage Electrical pressure, the force, which causes current to flow through a conductor.
Voltage must be expressed as a difference of potential between two points
since it is a relational term. Connecting both voltmeter leads to the same point
will show no voltage present although the voltage between that point and
ground may be hundred or thousands of volts.
Voltmeter A meter for reading voltage. It is one of the ranges in a multimeter.
Volume Calculation Period The specified length between reading and calculating volume data.
Volume Flow Rate Calculated using the area of the full closed conduit and the average fluid
velocity in the form, Q = V x A, to arrive at the total volume quantity of flow. Q =
volumetric flowrate, V = average fluid velocity, and A = cross sectional area of
the pipe.
VOS Velocity of Sound.
Warm Start A rebooting technique which will clear most operational errors, without
damaging either the data or configuration files. This causes the equipment to
boot from the RDRIVE, which is a solid state memory chip.
Watt Symbol W. The unit of power. One watt is the product of one volt and one amp.
Power (W) = Current (I) X Energy (E). (E = Volts)
Wavelength The distance between two points of corresponding phase in consecutive cycles
Web Page All the text, graphics, and sound visible with a single access to a Web site; what
you see when you request a particular URL.
Web Server The hardware and software required to make Web pages available for delivery
to others on networks connected with yours.
Web Site A collection of electronic "pages" of information on a Web server
Well, Development A well drilled in order to obtain production of gas or oil known to exist.
Well, Disposal A deep well in which to inject waste chemicals, etc., such as a well to dispose
of salt brine from the solution mining of salt dome gas storage caverns.
Well, Exploratory A well drilled to a previously untested geologic structure to determine the
presence of oil or gas.
Well, Gas A well which produces at surface conditions the contents of a gas reservoir;
legal definitions vary among the states.
Well, Marginal A well which is producing oil or gas at such a low rate that it may not pay for the
drilling.
Well, Stripper
Non-associated gas well capable of producing no more than 90 Mcf/day at its
maximum rate of flow.
Well, Wildcat An exploratory well being drilled in unproven territory, that is, in a horizon from
which there is no production in the general area.
Wellhead The assembly of fittings, valves, and controls located at the surface and
connected to the flow lines, tubing, and Casing of the well so as to control the
flow from the reservoir.
