Phylogeny Of Frac Sand

Since 1950, the silica sand that used in fracturing construction was come from Arkansas River; white sand came from Saint Peter layer in Ottawa, Illinois. In 1958, fracturing construction was using the brown silica sand from Brady. Although the silica sand is appear, but because of its low strength, only used in the oil well which less than 1500m. In 1960, the glass beads, plastic beads, walnut shell used in fracturing construction, but they are easily to be dissolved.

From 1970 to 1975, cured resin parcel quartz sand was appearing, the strength of frac sand is better than white silica sand and brown silica sand, but the long term conductivity is not so good. In 1979, the frac sand was appearing; it sintered by bauxite with higher strength, longer term conductivity and lower density. From 1980 to 1982, procuring resin parcel quartz sand used in business was appearing

In 1985, low density frac sand was appearing, this frac sand can prevent the lime scales. In 2002, the frac sand with ultra-low density was appearing and became the trend in oil and gas industry. High strength, low density, high crush rate and high conductivity are requested by oil and gas industry.
