Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine derivative of the formula:
wherein R
14
is a C
1
-C
24
straight chain or branched alkyl group; or a C
6
-C
24
aryl or arylalkyl group; R
15
is a C
1
-C
6
alkyl or a C
6
-C
30
aryl or alkylaryl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid (WSF) formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing dithiazine or dithiazine derivative and a corrosion inhibiting formulation may be used to inhibit corrosion in the well.
