Abstract: An apparatus (100) for operation in a tubular channel (199), the apparatus comprising a first part and a second part connected to the first part, wherein the second part comprises a first electronic device adapted to generate a data signal and a first communications device for wirelessly transmitting the generated data signal via a wireless communications channel, wherein the first part comprises a second communications device for wirelessly receiving the transmitted data signal via said radio-frequency communications channel.

Abstract: The invention relates to a system and a method for determining flow patterns of fluid in a production well. Especially, the invention relates to a method of determining flow patterns between and into oil production wells drilled in the Earth when flow is improved by water flooding. The system comprises a canister (1) said canister being located in said formation at a subterranean location within or proximate the wellbore, the canister being provided with an exit opening (5), a traceable component (4) being placed in the canister and able to pass through the exit opening and a release mechanism capable of releasing the traceable component when triggered by a triggering mechanism such that the traceable component enters the fluid flowing through the well through the exit opening and is present in the fluid flow in the wellbore.

Abstract: According to the method for well and reservoir management in open hole completions, a data acquisition module (100) is advanced through the wellbore and acquires data providing information revealing fractures in the wall of the wellbore, and at least one blocking system (1002, 3000), on the basis of the data acquired, is placed in the wellbore(199, 2199, 3006) at the location of a fracture in the wall. The data acquisition module (100) is advanced by interaction with a fluid present in the wellbore, and the data acquisition module acquires data providing information on its own position in relation to the wall (3005) of the wellbore (199, 2199, 3006) and is controlled on the basis of said data in order to maintain a distance to the wall of the wellbore during its advancement. A system for well and reservoir management in open hole completions is further disclosed.
