Abstract Hydraulic fracturing fluids used in tight gas wells may remain in the formation for extended periods before flowback because of operational and environmental constraints. This prolonged shut-in period can increase the potential for additional formation damage. This study evaluated the long-term impact, up to 6 months, of a hydroxypropyl guar-based (HPG) cross-linked fracturing fluid on the permeability of Scioto tight sandstone under high-temperature reservoir conditions.

Saline aquifers, particularly those in carbonate formations, offer a promising option due to their widespread prevalence and significant storage capacity.

Abstract The use of seawater as a base fluid for fracturing applications can significantly reduce freshwater consumption; however, the high salinity and reservoir temperatures degrade polymer networks and destabilize rheological properties. Hence, this study develops and measures a crosslinked fluid for high-temperature wells (i.e., 300 °F) with low polymer loading (40-lb/1000-gal), utilizing Arabian Gulf seawater with a total salinity of 58,850 ppm.
