Provide habitat for wildlife by planting native vegetation in your yard.The spread of non-native species has greatly impacted native populations around the world. Invasive species compete with native species for resources and habitat. They can even prey on native species directly, forcing native species toward extinction. STOP DEFORESTATION AND CUTTING TREES ILLEGALY.

Crown Management Jakarta Capital Discussion - Can anyone tell me what this frac sand?
Answers: 4 Views: 576 Rating: 2 Posted: 11 years ago

Some subsurface rock units such as organic shale contain large amounts of oil, natural gas or natural gas liquids that will not flow freely to a well. They will not flow to a well because the rock unit either lacks permeability (interconnected pore spaces) or the pore spaces in the rock are so small that these fluids cannot flow through them.

The hydraulic fracturing process solves this problem by generating fractures in the rock. This is done by drilling a well into the rock, sealing the portion of the well in the petroleum-bearing zone, and pumping water under high pressure into that portion of the well. This water has been treated with a chemical that creates a viscous gel. This gel facilitates the water's abillity to carry grains of frac sand in suspension.

Large pumps at Earth's surface increase the water pressure in the sealed portion of the well until it is high enough to exceed the breaking point of the surrounding rocks. When their breaking point is reached they fracture suddenly and water rushes rapidly into the fractures, inflating them and extending them deeper into the rock. Billions of sand grains are carried deep into the fractures by this sudden rush of water. Over one million pounds of frac sand can be used to stimulate a single well.
