DIAMINE TERMINATED PRIMARY AMINE-ALDEHYDE SULFUR CONVERTING COMPOSITIONS AND METHODS FOR MAKING AND USING SAME

摘要

A new class of sulfur scavenging or converting compositions is disclosed comprising diamine terminated, amine-aldehyde adducts, where the adducts are substantially bimolecular amine-aldehyde adducts and the composition is substantially free of trimer and/or triazines. Methods for making and using the new class of sulfur scavenging or converting composition are also disclosed. A plot of weekly average water production (M3/day) versus production week shows the beneficial effect of using such a composition after optimization, adjusting amount based on noxious sulfur content, and after multi-point injection of the composition into well fluids.
