Neuman et al. [12] tested acid fracture conductivity at closure stress higher than 5000psi for Brazil off-shore carbonates and found that acid fracture conductivity can be retained at closure stress higher than 5000psi in case of channel created in the surfaces.

Small-scale and Artisanal mining Often one refers to “Artisanal and Small-scale Mining” (ASM) when talking about “mining by individuals, groups, families or cooperatives with minimal or no mechanization, often in the informal (illegal) sector of the market” (Hentschel et al., 2002).
