Claim 0:
1. A method for well testing under full field production, wherein well flow from multiple wells (200a-200d) 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 the steps of:
(a) isolating well flow from one of the multiple wells (200a-200d) to define an isolated well and 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 testing,
(b) running the well flow from the isolated well (200a-200d) through a dedicated test slug suppression and gas removal unit (310) and the at least one isolated and dedicated inclined tubular separator (11a-11e) to initiate a test period,
(c) running well flow from non-isolated wells (200a-200d) through the production slug suppression and gas removal unit (100) and non-isolated inclined tubular separators (11a-11e),
(d) measuring volumes of gas, oil and water produced for the isolated well (220a-200d),
(e) adding the respective gas, oil and water produced for the isolated 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 gas, oil and water produced for the non-isolated wells (200a-200d) from the production slug suppression and gas removal unit (100) and the non-isolated inclined tubular separators (11a-11e), and
(f) removing the isolation of the isolated well (200a-200d) and at least one isolated and dedicated inclined tubular separator (11a-11e) to end the test period.
