Hasła / Terms beginning with W
- Well bottom
Lower bottom part of a drilling well, perpendicular to the well axis.
- Well depth (TVD - True Vertical Depth)
Vertical distance measured from well bottom to its top on the ground surface (in metres).
- Well length
Distance from the ground surface to the well bottom measured along the well axis.
- Well logging curve
Log of a specific property versus depth. For example, temperature log, i.e. logging tool-measured temperature plotted versus depth.
- Wet (condensate) gas
Natural gas associated with crude oil. Besides methane, the gas contains heavier hydrocarbons that precipitate as condensate at changes in reservoir pressure.
- Wireline Logging (WL)
Geophysical well logging with wireline-mounted tools made upon drillstem retrieval from the well.
