The TITAN System was deployed on a semi-submersible rig in the North Sea for a slot recovery operation where the operator required the 9 5/8’’ casing to be pulled approximately 50m below the 13 3/8’’ shoe into the openhole.Experience from the field has shown that it has frequently not been possible to recover casing from the openhole using conventional methods.
The TITAN System unifies casing cutting and recovery with a downhole hydraulic power tool, in a single trip operation.The downhole adaptability of the TITAN System ensures and maximises the recoverable casing in challenging circumstances by utilizing the pulling capacity of the hydraulic power tool with added repeatable casing cutting capability.

Complete well breakdown
Long String Recovery Operational time savings for TRIDENT System versus Conventional operation
1 P/U TRIDENT System including EZSV packer and RIH to set depth at 1330m 2 Set EZSV
a. Pull up to install Marine Swivel and land in wellhead at 382m – 4 hours 3 Pull up to cutting depth 1321m and perform cut. Attempt to pull free and circulate.
a. POOH to lay out Marine swivel and install inline spear – 5 hours 4 Pull up to cutting depth 1264m and perform cut. Attempt to pull free and circulate.
a. POOH to lay out Inline Spear and install Marine Swivel – 4 hours 5 Pull casing to surface with TRIDENT System
a. POOH and L/O cutter assy, P/U and M/U Spear assy and RIH – 4 hours
Short String Recovery Operational time savings for TITAN System versus standard DHPT operational
1 RIH with TITAN System to pull free from 1264 to 1321m – No go 2 Release Spear and perform new cut at 1288m
a. POOH with DHPT and RIH with cutter and Marine Swivel to cut at 1288m– 14 hours 3 Attempt to pull free with DHPT, 9 5/8’’ fish from 1264 to 1288m – Nogo
a. POOH with Cutter and Marine Swivel and RIH with DHPT – No go – 9 hours 4 Release Spear and perform new cut at 1276m and pull free csg from 1264 to 1276m
a. POOH with DHPT and RIH with Cutter and Marine Swivel to cut at 1276m – 9 hours b. Pooh with Cutter and Marine Swivel and RIH with DHPT pull free from 1264 to 1276m
– 9 hours 5 RIH with TITAN and pull free from 1276 to 1288m
a. RIH with DHPT to pull free from 1276 to 1288m 6 RIH with TITAN, attempt to pull free from 1288 to 1321m – No go, perform new cut at
1300m a. RIH with DHPT, attempt to pull – No go, POOH, L/O DHPT and RIH Cutter and swivel
to cut at 1300m -9 hours 7 Unable to pull free with DHPT, next decision was to try the Washover shoe to wash over
the 9 5/8’’ casing which was successful in 2 steps.
