A new range of four gastight well suspension plugs, designated the Lock series, was unveiled by well integrity specialist Archer during ONS.
The series comprises four application-specific products: SafeLock, for short to medium term suspension periods; TimeLock for longterm suspension or harsh conditions; StormLock for storms, extended periods or harsh conditions; and LastLock, for total security in permanent well abandonment.
Rapid set and seal, easy move and reset, and a 100% retrievability record combine to provide absolute protection, with high efficiency and low operating costs, according to Rolf Haaland, VP and GM of Archer’s Oiltools division. ‘When sealing wells for suspension or abandonment, barrier failure can prove disastrous – for rig teams, the local environment and an operator’s reputation. The advanced technology behind our new Lock series of well suspension plugs provides the assurance and protection the industry needs.’
According to Archer, the combination of advanced seal engineering, pressure testing from below and pre-set seal surface cleaning takes Lock seal assurance to ISO 14310 V0 level. The company attributes Lock’s impressive retrieval record to the high-differential ball valve, simplified slip design, anti-debris filter and conclusive pull-and-rotate release mechanism. Should well conditions prevent normal retrieval, the top section can be milled easily to release the slips, it adds.
