Publication number: 20230340856Abstract: In the process of suspending a subsea hydrocarbon well (1) after finalizing the completion operation and prior to stimulation of the well and putting the well on production, preinstalled upper and lower glass plugs (11, 12) are used as temporary barriers in the tubing. The plugs allow various tests to be performed before the lower plug (12), below the production packer (10), is broken; the upper plug (11) located above the downhole safety valve (13) then forms one of the barriers required to suspend the well whilst the Blow Out Preventer (BOP) is removed and Xmas tree installed, at which point the upper plug (11) is broken.Type: ApplicationFiled: April 20, 2023Publication date: October 26, 2023Inventors: Jan Ove SOERHEIM, Lars ALBERTSEN, Rune WOIE

Patent number: 11585179Abstract: The invention relates to the drilling of subsurface oil and gas wells and the installation of subsurface equipment (11). A lifting vessel 7 brings heavy equipment such as Xmas trees or manifolds and wet parks this equipment (11) on the seafloor (5) during good weather when the significant wave height is low. The equipment (11), once it is underwater, has much lower weight and may easily be moved into place onto a wellhead (10) at an appropriate time using lower capacity lifting gear. The timing of this operation is much less sensitive to weather conditions because the equipment does not need to pass through the splash zone (sea surface). This makes for efficient use of expensive drilling rig time, and allows for acceleration of production of first wells on the template as critical heavy lifts could not else be done until rig has left the location. (FIG. 1).Type: GrantFiled: October 4, 2021Date of Patent: February 21, 2023Assignee: CONOCOPHILLIPS COMPANYInventors: Rune Woie, Leif Kvarme

Publication number: 20210285317Abstract: The invention relates to a method and system for monitoring strain data on a subsea wellhead and associated tubing especially during a drilling or completion operation when the wellhead is connected via a riser to a drilling rig. The bending stresses on the wellhead assembly can be modelled and monitored, based on strain data from strain gauges attached to the conductor, surface casing and possibly also inner tubing. The strain gauges are located where maximum bending stresses occur, at around seafloor level. Data from the strain gauges is transmitted by radio to a receiver unit on the template, from which it may either be transmitted to the surface or stored and retrieved by divers or subsea vehicles.Type: ApplicationFiled: March 11, 2021Publication date: September 16, 2021Inventors: Rune WOIE, Harald NEVOEY

Patent number: 6575242Abstract: When production testing a permeable first formation, fluid flowing out from the first formation is subjected to a pressure measurement and a flow rate control. In order to avoid bringing up the fluid flowing out during the production test to a surface position, where the fluid's inherent explosion and fire risk as well as poisonousness would cause substantial problems, a fluid flow path is arranged for fluid transfer between the first formation to be production tested and a second permeable formation. The fluid flow path is preferably constituted by a channel-forming pipe. From this channel, the second permeable formation receives the fluid and keeps it for some time. In the position of use, the apparatus is assigned sealing devices such as annulus packers, which are placed such that fluid flow between the formations is limited to only follow the fluid flow path.Type: GrantFiled: October 2, 2001Date of Patent: June 10, 2003Assignee: Shore-Tec ASInventor: Rune Woie

Publication number: 20020017385Abstract: When production testing a permeable first formation (4), fluid flowing out therefrom is subjected to a pressure measurement and a flow rate control. In order to avoid bringing up the fluid flowing out during the production test to surface position where the fluid's inherent explosion and fire risk as well as poisonousness would cause substantial problems, a fluid flow path arranged for fluid transfer between the formations (4, 6) is established between said first formation (4) to be production tested and a second permeable formation (6), said fluid flow path which, in a suitable apparatus, is constituted by a channel-forming pipe (8). From this channel second permeable formation (6) receives said fluid and keeps it for some time. In the position of use, the apparatus is assigned sealing means, i.a. annulus packers (10, 11, 12) which are placed such that fluid flow between the formations (4,6) is limited to only follow said fluid flow path.Type: ApplicationFiled: October 2, 2001Publication date: February 14, 2002Inventor: Rune Woie
