Helix Well Ops UK (Well Ops), a business unit of international energy services company Helix Energy Solutions Group (Helix ESG), has successfully completed a three-month campaign for West Africa’s first well intervention work and subsea well operations conducted from a mono-hull intervention vessel.
Operating the 132-metre (433ft) long Well Enhancer, Well Ops performed a subsea tree change out, well suspensions, well maintenance and production enhancement on seven wells in water depths of up to 471m (1,545ft). This project represents the deepest operation conducted from Well Enhancer since it joined the fleet in 2009.
The Well Enhancer’s arrival in the waters west of Africa marked the emergence of mono-hull-based well intervention services in a region that is experiencing rapid development. Compared to rig-based methods, intervention programs delivered from mono-hull vessels provide numerous operational and cost benefits to operators.
