Light crude oil is liquid petroleum that has a low density and flows freely at room temperature.

it has a low viscosity, low specific gravity and high api gravity due to the presence of a high proportion of light hydrocarbon fractions.

it generally has a low wax content.

Light crude oil receives a higher price than heavy crude oil on commodity markets because it produces a higher percentage of gasoline and diesel fuel when converted into products by an oil refinery.

See marine loading arm.

Overburden pressure of rocks at a depth.

A technique using a suite of logs that are part of the drilling bha.

The formation properties are measured while drilling (although 40 to 60 feet back from the bit) and the information is pulsed to the surface.

Liquefied natural gas carrier, which is a sea vessel used to transport liquefied petroleum gas (lpg).

Abbr.

Deep laterlog / liquid level detection / log linear detrending

Having an affinity for the suspending medium, such as bentonite in water.

An essentially full-opening valve installed immediately below the kelly, with outside diameter equal to the tool joint outside diameter.

A drilling mud that contains a minimum amount of solid material (sand, silt, and so on) and that is used in rotary drilling when possible because it can provide fast drilling rates.

See low-solids mud

A colloid that is not easily precipitated from a solution and is readily dispersible after the precipitation by an addition of the solvent.

Commercial clay chiefly of the calcium montmorillonite type and having a yield of approximately 15 barrels per ton.

Materials added to the mud in varying amounts to control or prevent lost circulation.

Classified as fiber, flake, or granular.

A surface device used in slickline operations to keep the line lubricated and provide grease for pressure control.

An essentially full-opening valve installed immediately below the kelly, with outside diameter equal to the tool joint outside diameter.
