In order to process and transport associated dissolved natural gas, it must be separated from the oil in which it is dissolved. This separation of natural gas from oil is most often done using equipment installed at or near the wellhead. The actual process used to separate oil from natural gas, as well as the equipment that is used, can vary widely.

SAND AND SAND MINING Part I. Source: Unknown Uses of sand This resource is sand, not sand and gravel. Its primary source is sand dunes, therefore Michigan ranks third in the US in industrial sand production. Silica sand is the major component of glass, foundry molds, and abrasives. It is also used in ceramics, on golf courses, and as a filter medium.
