Global Horizontal Irradiance (GHI) is the amount of terrestrial irradiance falling on a surface horizontal to the surface of the earth. GHI can be measured with a variety of instruments. The most common instrument used to measure GHI is called a pyranometer which has a hemispherical (180°) view angle.

Gravel pack design & evaluation | SPE

So far, horizontal gravel packing has been applied almost exclusively to open holes with screens in them. If a formation has a high permeability, and therefore, a high fluid-loss rate, placement of a gravel pack may be prevented by premature dehydration and bridging of the gravel-pack sand in the wellbore/screen annulus.
