Lightweight well access solutions: Reduce costs and improve efficiency in shallow and deepwater operations.

Lightweight well access solutions refer to a family of modular, smaller-footprint equipment designed to perform essential well maintenance and diagnostics without the need for a full drilling rig.

These "rigless" solutions, which include specialized pressure control equipment and modular intervention towers, are typically deployed from smaller, less expensive construction or anchor-handling vessels. Their main appeal lies in their significantly lower day rates and mobilization costs compared to large rigs, making light and medium well intervention economically feasible. The ongoing evolution of these systems focuses on increasing their operational envelope to handle more complex well interventions, expanding their overall utility.

FAQs:

Q: What is the main commercial benefit of a lightweight well access solution?
A: The substantial reduction in operational costs, primarily through the use of smaller vessels and reduced mobilization time, is the key commercial benefit.

Q: What types of vessels are typically used to deploy these lightweight systems?
A: They are usually deployed from specialized vessels such as construction support vessels (CSVs) or multi-purpose supply vessels, rather than a full-sized drilling unit.

Q: How does a lightweight solution handle the pressure control aspect of well access?
A: It utilizes highly specialized, compact pressure control equipment, such as smaller-footprint lubricators and intervention riser systems, often rated for high pressure.
