gas coning

gas coning

[¦gas ′kōn·iŋ]
(petroleum engineering)
The tendency of gas in a gas-drive reservoir to push oil downward in an inverse cone contour toward the casing perforations; at the extreme of coning, gas, not oil, will be produced from the well.

TNO was showing some modeling technology that couples multi scale (time and space) models for studying production instabilities such as slugging and gas coning.
These innovative solutions are: the EquiFlow[TM] Oil Selector[TM] valve, which is capable of significantly reducing unwanted water or gas production without wellbore intervention; EquiFlow[TM] inflow control devices, which delay early water or gas coning, thereby increasing recoverable reserves; and PetroGuard[TM] Advanced Mesh screen, which provides reliable sand control in heavy oil and poorly sorted sand environments.
It not only extends the length of reservoir sections but also places the wellbore in the optimum position, thus enhancing production while minimizing gas coning and water production.
