All three parts of the name are subject to change, especially in the case of a producing well. When an oil or gas field is sold, the operator name will change. If a field is unitized for enhanced oil recovery, the well number and lease name will change. Almost three million wells have been drilled for oil and gas in the United States. [2]
WOC – water/oil contact (or oil/water contact) WOE – well operations engineer (a key person of well services [citation needed]) WOM – wait/waiting on material; WOR – water-oil ratio; WORKO – workover; WOS – west of Shetland, oil province on the UKCS; WOW – wait/waiting on weather; WP – well proposal or working pressure
Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.
Water Transfer: The act of moving water from one location to another either to support drilling and completion activity when a well is being made or to remove flowback and produced water after the well has been made and oil and gas begin flowing back. Well logging: The practice of making a detailed record (well log) of the geologic formations ...
For oil and gas well allocation, Newfoundland and Labrador and Nova Scotia Offshore Areas, Drilling and Production Regulations, [43] for example, requires accuracy within ±5%. In general, the total uncertainty of the allocation system is related to measurement uncertainty of each measured input.
Water injection wells may be located on- and offshore, to increase oil recovery from an existing reservoir. Normally only 30% of the oil in a reservoir can be extracted, but water injection increases the recovery (known as the recovery factor) and maintains the production rate of a reservoir over a longer period.
