Jul 16, 2020 · The buttes (sandstone pillars) were created through the process of erosion, the gradual wearing away of earth by water, wind, and ice. The buttes formed over millions of years, as streams slowly cut through a mesa or plateau. The hard top layers of buttes, called caprock, resist weathering and erosion. But the softer rock surrounding the ...

However, water invasion into tight sandstones can introduce some formation damages, such as water phase trapping, fluid sensitivity, and stress sensitivity (She et al., 2020; Bahrami et al., 2012; Zhong et al., 2019; Boek and Tardy, 2011).For an unconsolidated or weakly consolidated sandstone formation, sand production is the main obstacle affecting the normal production of oil and gas well. The sand control techniques normally used are divided into sand control without screen and sand control with screen.The results show that for unconsolidated sandstone formations, high permeability corresponds to the high injection rate required for fracture initiation; low strength of the rock base material and low effective stress under great leak-off of fracturing fluids correspond to low fracture pressure.
