Case Study – Autofill

Major Offshore Operator Increases Efficiency 20%

Offshore wells in HPHT environments demand uncompromising safety, operational reliability, and efficiency throughout the completion phase.


The problem

In a recent Gulf of Mexico project, a leading offshore service provider faced challenges with traditional completion procedures that relied on manual filling of the tubing string during run-in-hole.  


This approach not only consumed excessive rig time but also introduced risks associated with fluid handling and uncontrolled influxes. ​

The solution

3.5” Fantom™ shatter ball seat (SBS) and barrier combination was installed in an open-port configuration, enabling fluid from the annulus to fill the tubing string naturally during RIH. Once the target depth was reached, a ball was dropped to activate the internal sleeve, closing the ports and establishing upstream pressure integrity which allows effective execution of remaining completion activities. 

When completed, the Fantom™ SBS and barrier are easily opened without intervention, resulting in genuine full-bore ID and a reduction in rig time. This dramatically improved efficiency while increasing safety and profitability.

The Result

A massive increase in efficiency and well control generated a reduction in rig time which delivered huge cost savings.
