Water Based Mud (WBM) filter cake treatment

Arcasolve™ for WBM Filter Cake Removal

The permeability of the producing wellbore face within the reservoir is severely reduced by drilling mud/drill-in fluid filter cake damage deposited during drilling.  This filter cake is typically comprised of solids, weighting agents and drill cuttings fines e.g. calcium carbonate, and in the case of polymer containing fluids, polymers. 

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.

Arcasolve^TM is very effective for the clean up of water based carbonate-polymer muds or drill-in fluids. The photographs below show the effect of Arcasolve^TM on a filter cake produced using a commercial water based mud formulation containing calcium carbonate, starch and xanthan. 

The acidizing components of the formulation dissolve the carbonate component of the filter cake and the polymer breakers hydrolyse the polymer components.  This allows a complete treatment of filter cake in a single stage process.
