In response to customer requests for OBM cleanup systems effective in a range of dense brines Cleansorb has optimised its Arcasolve Orca^TM formulations to deliver effective cleanup in several of the most common high density carrier fluids including potassium formate, calcium chloride and sodium bromide. 

With the increasing use of openhole horizontal/directional completions, drawdown alone cannot be relied on to cleanup filtercake along the whole of the wellbore.  Effective removal of this mud filter cake is vital to optimise well performance and NPV.

It is expected that Arcasolve Orca^TM formulations effective in all common brines will be available by the end of 2009.
