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.
