How can a longitudinal split in the casing jeopardize fracturing operations?
The operator can no longer pressurize the wellbore nor shift the sliding sleeves with a ball drop system. The longitudinal split prevents any chance of integrity insurance: The stimulation is on hold and cannot be resumed as long as you haven’t treated the impairment.
Investigation on the nature of a split.
When experiencing a casing failure, operators might call third parties to investigate an anomaly within the completion.
Contractors can deploy a camera and Caliper with temperature sensors to Livestream and figure out about the impairment. The camera can quickly identify the longitudinal split in the casing joint. The Caliper will determine the extent of the split and what the internal restrictions are. All this gives the customer the ability to investigate the source and the impairment further, so they can elect the best remedial solution to mitigate the issues on their wellbores.
Casing splits threatening the production.
Operators invest in costly technologies for well integrity management. They expect their oil and gas-producing wells to withstand significant production rates. Any failure to achieve this objective may result in economic losses. Split casing means a downhole impairment – resulting from corrosion or damage generated from previous tool-runnings that is now causing surface leakages.
Fixing a longitudinal split
The Remediation involves sealing off the split casing section by covering and isolating the impairment with a casing patch. Saltel Xpandable steel Patch restores the casing integrity and guarantees at the same time one of the best drift IDs in the market. This drift ID allows the operator to quickly resume running tools during subsequent phases of the well’s life.
