Designed for the World's Most Challenging Wells

The UROS-CT is designed to be run in the close tolerance, under-ream applications found in some of the world’s most challenging offshore fields. This close tolerance (CT) model is engineered to extreme tolerances enabling it to negotiate the tightest restrictions.

Designed with a precisely formed cross bow curvature, the UROS-CT has no ‘knife edges’ to reduce the risk of subsea well head damage on insertion. This also adds additional strength to the bows.

The UROS-CT centralizer is designed to be ultra-flexible to ease the string to TD having the highest flex rating.

Key Benefits

  • Low-profile design provides peak flow-by performance to reduce the surge effect
  • Designed to challenge the traditional and extremely costly centralizer sub market
  • Engineered to precise ring-gauge tolerances, because every millimeter saved allows for greater expansion in the open hole

Targeted applications

  • Under-reamed wells sections
  • Tight casing applications
  • Deepwater
  • Highly deviated wells
  • Horizontal/ERD wells
  • S-Type/J-Type
