The Subsea Intervention Device (SID) is the key to our subsea riserless light well intervention (RLWI) services. It is a self-contained modular subsea lubricator package, complete with electro-hydraulic control system. It can operate on both horizontal and vertical trees, with the ability to control the tree, if required.
The SID allows slick line or electric line tools to be run into live wells to carry out a number of operations throughout its life cycle, including:
Plug installation and removal
Stroking/cycling mechanical valves
PLT/MPLT logging
Perforating, punching and cutting
Milling out obstructions and debris removal
Changing out down-hole gauges and valves
The SID enables faster, more convenient access to the well bore for easy data acquisition, safety valve remedial work, well intervention, maintenance and repair; making scheduled and emergency subsea well intervention immediately practical and cost effective.
Together with SWS’ proprietary Intervention Compensation System (ICS), SID can be deployed from any suitable vessel of opportunity. This reduces the dependency on specialist rigs or vessels, allowing the system to be in the field quicker at a reduced cost.
Utilising the SID system can significantly reduce the risk of production deferment and improve reserves recovery through planned data acquisition or emergency well maintenance.
Suspending wells by installing suspension plugs with SID can reduce decommissioning cost and risk, by reducing spread cost, and allowing more flexible and informed abandonment strategies.
