Systems and methods for scavenging sulfur-containing materials using a precursor scavenger material

A method of applying a scavenger material to a wellbore, the method comprising:

• providing a precursor scavenger material to a location within the wellbore, the wellbore extending through an earth formation, the precursor scavenger material comprising at least one of acrolein diethyl acetal, acrolein ethylene glycol acetal, or 3-hydroxypropanal;
• responsive to exposure to an acid or water in the wellbore, forming the scavenger material in the wellbore from the precursor scavenger material, the scavenger material comprising propenal;
• measuring a concentration of a sulfur-containing species associated with the wellbore;
• and
• adjusting a flowrate of the precursor scavenger material based on the measured concentration of the sulfur-containing species at a downhole location.
