Proved developed and undeveloped reserves
All of a company’s proved reserves, whether these have already been developed or not
Proved reserves, proven reserves, measured reserves
Proved reserves are those reserves that geological and engineering data indicate with reasonable certainty to be recoverable today, or in the near future, with current technology and under current economic conditions. Proved reserves are estimated volumes of hydrocarbon resources that analysis of geologic and engineering data demonstrates with reasonable certainty are recoverable under existing economic and …

Public Utility
A public utility is an organization that constructs and maintains the infrastructure for a public service (electricity, natural gas, water, sewage, telephone, etc.) and usually also provides the service behind the said infrastructure. Public utilities are usually regulated.
Pump off
To pump a well so rapidly that the oil level falls below the pump’s standing valve, rendering the well temporarily dry
Qatar LNG; Qatar Gas; North Field
Qatar is the largest exporter of LNG in the world; by 2010 it is expected to supply 30% of the world’s LNG. All of the RasGas LNG trains are located in Qatar’s Ras Laffan industrial area, drawing on gas from the giant North Field. RasGas I (trains 1 and 2) produces a combined 6.6 million …
Q-boat; Q-technology
Different type of seismic survey boat using Western Geco’s proprietary Q cable technology. This boat allows companies to record different signals in an easier manner than with a conventional cable. Q is the WesternGeco suite of advanced seismic services and technologies for enhanced reservoir delineation, characterization, and monitoring. On land and offshore, Q-Technology is playing …
Q-Flex ships, Q-Flex tankers; Q-Max ships, Q-Max tankers
The largest LNG tankers in existence with a 210,000 (Q-Flex) and 266,000 (Q-Max) cubic meter LNG capacity. Qatar Gas Transport Co ordered and will operate the first “Q-Max” having the capacity to carry 266,000 cu m of LNG, almost 80% more cargo than conventional LNG ships. Named the Mozah, it has a length of 345 …

Pressure regulation, pressure control
Pressure: formation pressure increases with depth; pressure prediction plot is used to forecast pressure distribution along the well path; pore pressure is the pressure at which pore fluids leave the formation and influx into the well; fracture pressure is the pressure where the formation breaks down (the aim is to remain between these two former …
Pressure relief valve; Pressure control valve
A valve designed to open automatically to relieve pressure and keep it below a designated level.
Pressure survey; Downhole pressure and temperature survey
A pressure survey is conducted after the first year of production in a gas well and consequently annually. The survey is required to review the decreasing trend of the pressure in a gas reservoir in order to estimate the amount of gas that remains. Since the pressure in a reservoir decreases in a linear manner …
