ClearPAC LT, ClearPAC MS, and ClearPAC HD temperature and density application domains.
Maximize fracture conductivity with polymer- and solids-free fluids
ClearPAC fluid system for gravel packing reduces formation damage and increases productivity. Gravel packing is more efficient when a fluid system has the flexibility to meet well specific requirements.
Fluids from the ClearPAC system do more than simply carry sand. They're designed with a high tolerance to oil-base-fluid contamination and are effective in long intervals of open and cased hole. The fluids use viscoelastic surfactants (VESs) for excellent suspension properties even at very low shear rates.
These solids- and polymer-free fluids are compatible with brines having densities to 14 ppg [1.68 sg], making them ideal for well control. Produced oil acts as the breaker, and fluids break down totally during production in wells with temperatures from 80 to 300°F [26.7 to 148.9°C].
The ClearPAC system comprises
ClearPAC LT fluid optimized for applications at low temperatures and densities
ClearPAC MS fluid specifically designed for simultaneous gravel packing and mud filtercake removal
ClearPAC HD fluid compatible with brines having densities to 14 ppg [1.68 sg] and is well suited for well control.
Mudcake cleanup
Enhancing productivity often requires mudcake cleanup, which is best achieved by integrating the mudcake cleanup additives with the gravel-pack fluids. An efficient postflush-type treatment relies on diffusion through the gravel-pack fluid. A diversion technique prevents all cleanup treatment from disappearing into the formation once a fraction of the mudcake is dissolved.
