Case Study: WARP Fluid Technology Shows Value as Alternative to High-Density Brines

Challenge: The 8 ½ in. interval from 350 m to 4,940-5,290 m (1,148-16,207 ft) was drilled with PARADRIL (SBM). The initial mud weight to drill the interval was 10.4 lb/gal (1.25 s.g.). At 5012 m (16,443 ft), a gas influx was observed and the mud weight was raised to 15.4 lb/gal (1.85 s.g.) to TD the well while avoiding a well control incident.

Solution: M-I SWACO proposed the operator use a paraffin-based WARP system as an alternative for the completion operation. Laboratory tests were performed showing the difference in sag factor between the PARADRIL drilling fluid and the WARP drilling fluid after three and seven days, even that WARP rheologies were lower than the PARADRIL rheology.

Result: The application of the WARP system proved highly successful on all fronts, including:

  • No problems opening and closing the valves on the DST string after the WARP system was static for three days prior the well test and during the well test.
  • No sag observed during trips.
