A method of removing hydrogen sulfide from a subterranean geological formation includes injecting a drilling fluid suspension in the subterranean geological formation. The drilling fluid suspension has a pH of 10 or more and includes a layered triple hydroxide material, including manganese, cobalt, and iron, in an amount of 0.01 to 0.5 precent by weight of the drilling fluid suspension. The method further includes circulating the drilling fluid suspension in the subterranean geological formation and forming a water-based mud and scavenging the hydrogen sulfide from the subterranean geological formation by reacting the hydrogen sulfide with the layered triple hydroxide material in the water-based mud.

Wellbore and geologic formation desulfurization process

A method of removing hydrogen sulfide from a subterranean geological formation includes mixing a zinc-imidazolate material, ZIF-8, in an amount of 0.1 to 2.5 percent by weight with an organic liquid containing one or more unsaturated oils to form a drilling fluid suspension with a pH of 10 or more. The method includes injecting the drilling fluid suspension in the subterranean geological formation, circulating the drilling fluid suspension in the subterranean geological formation to form an oil-based mud, and scavenging hydrogen sulfide from the subterranean geological formation.
