Patent number: 8640776Abstract: The present invention regards a device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection/gas lift system for fluid injection. The device comprises a outer hollow housing (1) with an internal body (2) moveable within the outer housing (1) with an internal bore (3) which in a first closed position is closed with a metal to metal seal system between the outer housing (1) and the internal body (2), which internal body (2) is operated by pressure differential across the internal body (2), where the internal body (2) is designed with slots (4) forming outlets of the internal bore (3) which in an open position of the device is positioned outside of the outer housing (1).Type: GrantFiled: May 25, 2012Date of Patent: February 4, 2014Assignee: Petroleum Technology Company ASInventors: Magnar Tveiten, Øyvind Stokka, Erling Kleppa, Tom Norland

Patent number: 8291981Abstract: The present invention regards a device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection/gas lift system for fluid injection. The device comprises a outer hollow housing with an internal body moveable within the outer housing which in a first closed position is closed with a metal to metal seal system between the outer housing and the internal body, which internal body is operated by pressure differential across the internal body. The internal movable body is connected to the outer hollow housing by means of a retainer key. The retainer key comprises a shear arrangement and is arranged to keep the valve in a fixed closed position, where fluid pressure is to overcome the pretension of the retainer key in order to open the device. When the device is shear opened, it can be kept in this open position as the retainer key is locked to the outer hollow housing.Type: GrantFiled: September 9, 2008Date of Patent: October 23, 2012Assignee: Petroleum Technology Company ASInventors: Magnar Tveiten, Øyvind Stokka, Erling Kleppa, Tom Norland, Ole Sevheim
