17 1/2" FAST ILS – Stabiliser Reamer | UK Central North Sea

UK CNS CampaignUK Central North Sea2020

33,978 ft drilled & reamed700 rotating hrs2 wells0 gauge lossall tools re-runnable

After 4 wells where 14 ILS tools were damaged beyond repair, FAST was requested to demonstrate its wear resistance on two DD ILS mandrels. Both FAST ILS tools were in gauge on POOH and all re-runnable — compared to the DD company's enhanced product which suffered repeated undergauge wear. After use on 2 wells: 33,978ft drilled & reamed, 700 rotating hours, zero wear on all FAST ILS runs.

Build to 30° and hold tangent on RSS across 4 wells through Tertiary and Upper Cretaceous formations. Two 17½" FAST stabilisers drilled and reamed a combined 124,402ft in 1,955.8 hours across 4 wells. All stabilisers confirmed in gauge after every run via NO-GO ring gauge. All 4 × 13,000ft casing strings run without incident. No repair costs incurred by operator.

Build inclination from 0° to 40° and turn azimuth 164° on a Push-the-Bit RSS drilling system in water based drilling fluid. The 17½" FAST Stabiliser Reamer drilled and reamed 4,949ft in 48.25 hours. A NO-GO ring gauge confirmed the stabiliser was in gauge. No torque fluctuations, no vibrational events recorded. Section drilled and casing string run without incident.
