Reliable isolation of annulus, sealing of unstable formations, eliminating risks of shallow gas blow out,reduction of conductor RIH and cementing time, environmental friendly,no risk of soils washout around neighboring conductor casing, capability of driving deviated conductor casing strings – these are main advantages of conductor driving as compared with drill and cement option.
Trident Group of companies offers integrated conductor driving services from a jack-up rig, crane barge, as well as from the drilling unit of a fixed offshore platform.
This technology is applied in 90% of offshore drilling operations, as it is optimal in all senses. To use it properly, one should have been doing a right planning at the stage of taking principal technical decisions already, as it is necessary to make provisions of the use of the correct casing and connector, to determine a driving depth and chose optimal casing shoe basing on the soil physical and mechanical properties in the section. Trident are ready to provide full range of assistance on these matters at the stage of engineering. Correct application of this technology allowed our Clients to reduce the time for conductor setting significantly, thus allowing financial savings.
We enjoy a fleet of own equipment, tooling and high qualified personnel who successfully took part in quite a number of conductor driving projects on Russian shelf, which fact makes Trident the most experienced and qualified conductor driving contractor in Russia.
To add, Trident provides services on slot recovery on offshore fixed platforms if either there are abandoned wells, or wells not used on the other reasons (borehole collisions, poor tightness).
