Abstract
Stabilized sulfide control compositions for oil well and related uses are provided which include a first ingredient selected from the group consisting of tetra (hydroxymethyl) phosphine (THP) or a salt thereof (THPS) and an amino phosophono chelant. The compositions are stabilized against cold-weather crystal formation and deposition by the presence of a morpholine-based stabilizing agent. Preferred compositions include the sulfate salt of THP, diethylenetriamine penta (methylenephosophonic acid) sodium salt, and morpholine.
