The gelling agent on the basis of synthetic polymer "Poly-Mud Thermogel" forms the stable crosslinked gel under elevated temperatures (from 70°С). The reagent is delivered in the form of dry powder, ready for application, adding of the crosslinking components is not required. "Poly-Mud Thermogel" is applied for use in the oil and gas industry for vertical conformance and water shut-off, elimination fluid loss when drilling and killing wells.
It is prepared on the surface, directly on well head area or in mud room. One of the components is the crosslinker works very slowly which under normal conditions that allows to store prepared solutions on a surface within several days. With temperature increase the process of crosslinking multiply accelerates.
The standard formulation of "Poly-Mud Thermogel" provides full crosslinking at temperature of 70 °C within 2.5-3 hours.
For bottom-hole formation zone treatment technologies concentration of 1-1.5% is effective.
For blocking 2-3% is effective.
