MAX-PRIME solution restores production to damaged well, saves $48,000 USD
An operator working a Barnett Shale well contacted Baker Hughes, a GE company (BHGE), to help with sand cleanout in order to restore the well to original production levels. Barnett Shale wells are typically known for drawing frac sand into the wellbore during production, eventually “sanding up” and stopping production all together.
Typical remediation treatments require bringing in a workover rig to pump fresh water in order to flush out the sand. This treatment requires a large amount of water and typically takes up to 5 days to remove the sand. Another option for remediation is by bailing the sand out with a bailer, although this carries the inherent risk of getting stuck and the resultant fishing job. The operator attempted a workover, removing tubing from the wellbore and then running the workover string into the hole until tagging up. Water circulation was then attempted, but yielded no returns due to the low formation pressure of the Barnett.
To effectively clean and restore the well, BHGE customized its MAX-PRIME™ reservoir drill-in fluid solution (RDIF) with the PERFFLOW™ water-based RDIF, formulated using the BRIDGE-WISE™ modeling software, to seal perforations and establish circulation.
