Integrated Well Abandonment Services

  • Port Harcourt - June 2015 - The Top Drive Casing System-TDCS which was first introduced into the Nigerian oil & gas market by AOS Orwell Limited (AOSO) in 2013 has yet again delivered another milestone in the Nigerian oil & gas industry. The TDCS has the capacity to ensure casing is run to TD safely with reduced personnel and eliminating the use of a stabber and a tong operator on rig floor.

    During a recent drilling operation on OBEN field, the AOS Orwell Casing & Tubing Running (CTR) crew of four (4) Nigerians, was deployed to run a mixed string of 9 5/8" OD & 10 3/4" OD VAM Top Casing. Prior to AOSO crew deploying the TDCS, the string had been run by another service provider using conventional tools to a depth of 10000ft (against a TD of 10480ft) but got stuck.

    The AOSO CTR crew requested the string be pulled out and ran the complete string using the TDCS thus reaching TD safely within the expected time by the client.

    As new technologies are being developed and introduced daily, the Nigerian oil & gas industry can be rest assured that AOS Orwell will continue to introduce technologies that ensure safety, operational excellence & efficiency to her clients.
