Hydraulic fracture stimulations, including the fracture geometry data from mineback mapping, for two crosslinked HPG gel treatments and one water treatment performed in vertical wells sited over underground coal mines in Queensland and New South Wales, are analyzed and compared to numerical fracture model predictions. The treating pressure gradients for all three treatments were higher than 1.1 psi per foot although the fractures produced were predominately vertical. The two crosslinked gel treatments produced fractures that were propped to a greater extent in the seam down-dip direction. The treatment using water formed two propped sub-parallel fractures and a small horizontal fracture at the top of the seam. Stress conditions in the rock and coal seams were significantly different at the sites. Laboratory parallel-plate scale-model studies are presented that demonstrate the nature of gravity current movement of dense fluid (both clear and slurry) down-dip in an inclined fracture model. Measured velocities are compared to theoretical calculations and to field measurements of asymmetrically propped fractures exposed by mining.
