This is in contrast with magnesium, immediately above calcium in the periodic table, which is virtually unreactive with cold water. The reaction forms calcium hydroxide, Ca(OH) 2 and hydrogen gas (H 2). The calcium metal sinks in water and after an hour or so bubbles of hydrogen are evident, stuck to the surface of the metal.

In brief, TSR is the reaction of calcium sulfate and hydrocarbons (beginning at temperatures of 120-140 °C) to form H 2 S and calcium carbonate. Because the resulting H 2 S can either move into the aqueous phase or react with iron in the reservoir minerals to form pyrite, the net effect of TSR can be to concentrate the gases (such as N 2
