n: a dynamic process by which different-sized sediments are separated from one another and deposited in different locations or layers as relatively uniform deposits. For instance, a high-energy mountain stream may leave only large cobbles and gravel in one location and carry finer sediments downstream to accumulate in a lower-energy environment, such as a lake.

a relative comparison of the formation to determine if there is a large difference between the size of the largest articles and the size of the smallest particles.

Usually used in underhole blast .colourless or lemon liquid,which can blast at 260 centigrade .

n: see sour crude oil.

crude oil that contains more than 1% total sulfur content. Typically applied as a label to oils with sour smell.

n: gas containing an appreciable quantity of hydrogen sulfide and/or mercaptans.

n: A gas containing hydrogen sulfide, carbon dioxide or mercaptans, all of which are extremely harmful.

gas rich in hydrogen sulfide, H2S.

Crude oil that containing harmful sulfur or sulfocompound.

defined in NACE MR-0175/ISO 15156 as exposure to oilfield environments that contain H2S and can cause cracking of materials by the mechanisms addressed by NACE MR-0175/ISO 15156.

a classification of materials that predicts satisfactory performance in hydrogen sulfide.
