Abstract:
1. A method for integrated horizontal selective testing of highly deviated or horizontally completed wells having one or more perforated zones and/or cased or open hole lateral branches to provide substantially real-time measurement of the production flow rates of a plurality of the perforated zones and/or lateral branches, comprising: with a coiled tubing deployment system, positioning a downhole flow rate measurement tool having a production flow rate measurement capability at a selected location within the wellbore relative to a selected perforated zone or lateral branch; with the downhole flow rate measurement tool measuring the production flow rate of the production fluid at the selected location; successively moving the downhole flow rate measurement tool to other selected locations within the wellbore and conducting other production flow rate measurements; and correlating the flow rate measurement data of each of the production flow rate measurements for confirming the production flow rates of each of the perforated zones and/or lateral branches.
