... Abstract This paper describes development of new subsea well intervention technologies that will support increased reservoir recovery. Subsea lubricator for seven inch and 10.000psi applications operated from dynamically positioned vessels has been developed and are now ready for use...

.... The selection of the floating vessel and the subsea system is therefore critical. The paper identifies various types of floating vessels along with subsea systems that can provide subsea well intervention. downhole intervention subsea well intervention lubricator downhole application log analysis...

... in the development are the lubricator system, where the lubricator resides on top of the injector, and the use of a tensioned coiled tubing configuration with a heave compensation system and a second coiled tubing injector at surface. A comparative risk assessment has been performed, and concluded that the overall...

... Abstract This paper discusses the design, construction, and Initial application of a structure for supporting a coiled tubing injector head, bottom hole drilling assembly and pressurized lubricator. The paper includes a discussion of the features desired for the structure and how these were...

... using a conventional lubricator mounted directly on the well. Datawas collected and compared with the flexible pipe run data. Results indicated that wirelineoperations can be conducted through a flexible pipe. A separate test conducted at the same time, measured possible wiretracking effects inside...

... successfully entered utilising a purpose built subsea wireline lubricator (SWL) deployed from both a dynamically positioned monohulled vessel and a Floating Production Facility. The SWL is designed to be deployed from a suitably equipped vessel, can be run on either 2 or 4 guidelines with or without diver...

... and more efficient wireline workover techniques, several subsea wirelining systems have been developed for deployment from a diving support vessel (DSV). 1,2 These systems do not tie the well bore back to the surface support vessel. A subsea lubricator assembly mounts directly on top of the subsea Xmas...

... created a need for a cost effective, self contained, well service system which can be rapidly mobilised to carry out a wide range of well intervention tasks. The subsea wireline lubricator system was developed to meet this need and allows a complete range of slick line and electric line downhole...

... tubing, and fishing. Typical wireline servicing equipment, as shown in Figure 1, consists of a lubricator (receiver for inserting wireline tools in a well), stuffing box, wireline blowout preventer (BOP), and wireline control equipment. In addition to this surface equipment, a special completion/workover...
