Claim 7:
8. A system for well testing under full field production, wherein well flow from multiple wells (200a-d) is run through a production system during full field production, the production system comprising a production slug suppression and gas removal unit (100) and a separator system (10) comprising multiple interconnected inclined tubular separators (11a-11e) for separating gas, oil and water from the well flow, comprising:
(a) controllable units (PV1-PV4, TV1-TV4) for isolating well flow from one of the multiple wells (200a-200d) from well flow of the non-isolated wells (200a-200d),
(b) a dedicated test slug suppression and gas removal unit (310) for separation of gas from the well flow from the isolated well (200a-200d),
(c) controllable units (HV1-HV2, HV4-HV5, WV4-WV5, LCVT, OV4-OV5) for isolating at least one of the inclined tubular separators (11a-11e) from the multiple interconnected inclined tubular separators (11a-11e) and dedicating the at least one isolated inclined tubular separator (11a-11e) for separation of the well flow from the isolated well (200a-200d), and
(d) units (GM, OM, WM) for measuring gas, oil and water volumes (m3/h) produced for the isolated well (220a-d),
wherein the units for isolating well flow (PV1-PV4, TV1-4) and units for isolating at least one of the inclined tubular separators (HV1-HV2, HV4-HV5, WV4-WV5, LCVT, OV4-OV5) collectively allow the well flow from the isolated well (200a-200d) to be run through the dedicated test slug suppression and gas removal unit (310) and the at least one isolated and dedicated inclined tubular separator (11a-11e) for a test period while well flow from the non-isolated wells (200a-200d) is run through the production slug suppression and gas removal unit (100) and multiple interconnected inclined tubular separators (11a-11e),
and comprising outlets, lines or both (311, 320, 330) for adding the respective produced gas, oil and water for the separated well (220a-200d) from the dedicated test slug suppression and gas removal unit (310) and the at least one isolated and dedicated inclined tubular separator (11a-11e) to the respective produced gas, oil and water for the non-isolated wells (200a-200d) from the production slug suppression and gas removal unit (100) and the multiple interconnected inclined tubular separators (11a-11e).
