Abstract

Method for the detection and quantification of the HS which measures concentration of the HS in the drilling mud including the steps of measurement of the initial concentrations of HS in free form and of the hydrogen sulphide HSand sulphide Sion species, dissolved in the sample of mud; acidification of the sample of mud, to generate gaseous HS, making the hydrogen sulphide (HS) and sulphide (S) ions dissolved in the mud and the HS precipitated in solid form in the scavengers react; measuring concentration of the gaseous HS formed following the first acidification; and relative system including at least: a mud sample collector; a unit measuring concentration of the hydrogen sulphide HSand sulphide Sion species in the sample; a unit for measuring concentration of the free HS; a unit to acidify the sample of mud; electronic controller and storage and processing of the measurements made.
