The “Ultra-Block” compound is designed to remediate disastrous loss of circulation zones of drilling fluid. The reagent can be used as a bridging agent before performing squeeze jobs. The factor of remediation is forming in the lost circulation zone of a membrane-type water wall due to high filterability under minimum differential pressure.
The composition is prepared based on the process water in concentration of 230 to 300 kg/m3, the volume of a circulated batch is calculated depending on the absorption power.
It is acceptable to prepare the composition based on any types of solutions, brines, and produced water.
