Dual leakoff beehavior in hydraulic fracturing of tight, lenticular gas sands

Conference ·
OSTI ID:6815737
Stimulation experiments conducted in anisotropic, naturally fractured, tight, lenticular, gas sandstones have shown the existence of a dual leakoff phenomenon. Below a threshold, leakoff increases by a factor of 50, slurries dehydrate rapidly, and screenouts occur in minutes. The leakoff has been shown to be controllable to some extent with 100-mesh sand. Results of three stimulation experiments are presented; three include a treatment that screened out, a minifrac experiment that showed the effectiveness of 100-mesh sand, and a final successful stimulation. 30 refs., 14 figs., 6 tabs.
