Title:
COMPOSITIONS AND METHODS FOR REDUCING HYDROGEN SULFIDE AND MICROBIAL INFLUENCED CORROSION IN CRUDE OIL, NATURAL GAS, AND IN ASSOCIATED EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/148397
Kind Code:
A3
Abstract:
The present invention provides compositions and methods for reducing hydrogen sulfide and/or mercaptans in oil and/or natural gas as well as for reducing microbial induced corrosion ("MIC") in oil and gas production environments. In particular, the subject invention provides environmentally-friendly compositions and methods for reducing hydrogen sulfide in oil and natural gas environments by controlling biocorrosive bacteria, such as SRB, therein.
