NORTH SEA, OFFSHORE SCOTLAND
Provide a cost-effective offshore filtration system that would enable the operator to avoid frequent cartridge filter replacements and to improve brine quality
Install a BaraClear™ twin filter press system, following a change in the offshore rig’s deck layout
On previous wells, an operator working offshore Scotland in the North Sea had encountered issues with filtration during gravel-pack completion operations. Poor sand quality in the formation caused damage to the filters, resulting in numerous cartridge filter replacements and excessive consumption of consumables.
A change in the rig’s deck layout opened up an opportunity to install a different filtration system.
The Baroid team recommended installing a BaraClear™ twin press filter system known for its success in gravel-pack operations. The unit operates with low-cost consumables and could deliver the performance needed to meet the customer’s requirements.
Following installation of the BaraClear system, filtration operations were executed with no issues. The number of cartridge filters used was significantly reduced, while the brine quality was improved.
The customer saved approximately USD 93,375 on cartridge filters. The filtered brine was in excellent condition for reuse on the next well, saving an additional USD 30,985.
Based on these results, using the BaraClear twin filter press system will now be the operator’s standard practice during wellbore cleanout and gravel-pack operations.
