Abstract
The present invention relates to a process and related apparatus for determining the presence and/or quantity of HS in the drilling debris of a subsoil layer comprising the following working steps: recovering the drilling debris of a layer; degassing the drilling debris from the previous recovery step, and separating a gaseous phase from said debris; clearing the gas released in the step of degassing, and conveying towards an HS detector; determining the possible presence and/or quantity of HS in the gaseous phase from the steps of degassing and clearing by means of a suitable means of detection; possible repetition of the previous phases at two layers, at least of the subsoil at different levels of depth in relation to the surface, with consequent determination of a distribution profile of HS in the subsoil.
