Abstract (en)
[origin: EP3085885A1] Disclosed is a method and computer program for monitoring the production of hydrocarbons from a reservoir via a well comprising a dual completion, each completion producing from a different reservoir formation. The method comprises performing the following steps for each completion: obtaining first data describing a first relationship between production flow rate and pressure between a point within the relevant reservoir formation and the well bottom; obtaining plural sets of second data describing a second relationship between production flow rate and pressure between the well bottom and the wellhead for a plurality of nominal values for a gas lift parameter; using the first data and the second data to determine a third relationship between casing pressure parameter within the well and the gas lift parameter; using the determined third relationship and the assumption that the casing pressure parameter is the same for each completion to determine the gas lift parameter for the completion under consideration.
