Uniform mud damage removal for WBM
Uniformly remove water-based mud damage in long openhole horizontal and deviated wells to increase productivity. ORCA for WBM treatment fluids are used to treat filter cakes arising from drilling with water-based drill-in fluids. ORCA for WBM treatment fluids are applied to treat new wells when first drilled or, as remedial treatments for wells already on production.
ORCA for WBM is particularly suitable for treatments in any formation drilled with water-based drill-in fluids containing carbonate weighting material or drilling fines in combination with biopolymers such as starch, xanthan, cellulose and other polymers such as PHPA and shale inhibitors. ORCA for WBM may also be used to treat filter cakes in wells drilled into carbonate formations, even if the drill-in fluid does not contain carbonate weighting material.
ORCA for WBM treatments are simple to mix and pump and are effective in a wide range of oilfield brine types and densities.
ORCA for WBM treatments optimize zonal coverage to regain and improve permeability along the payzone and improve mud damage removal for horizontal wells where lower draw down limits the ability for the wells to ‘self-clean’. Uniform wellbore cleanup ensures the cleanest wells and maximizes well production to deliver significant financial benefits. ORCA for WBM treatments on gravel packed gas production wells have contributed to some of the most productive gas wells in the world (SPE 112292).
