MARASEAL

MARASEAL^SM gel is formulated with low molecular weight polymers that allows for penetration into matrix pore spaces for a complete shut-off squeeze treatment. Unlike MARCIT^SM technology, which does not enter the matrix, MARASEAL^SM is specifically designed with low viscosity prior to crosslinking to aid in injectivity. The concentration of MARASEAL^SM is much higher, about five wt%, which results in a rubber-like ringing gel. When placed in small openings such as pore throats and small channels in cement behind casing, the result is total shut-off. MARASEAL^SM is a clear fluid that works by entering the reservoir and reducing permeability, not by simply plugging the perforation as in cement treatments.

MARASEAL^SM is never a drill-out problem. Simply wash through any material left in the pipe for easy clean out. The working time of MARASEAL^SM is easily controlled by adjustments to the formulation to achieve a working time to minimize rig time or maximize pumping time.
