摘要 |
The invention provides in a water injection system and in a water injection process for secondary oil and/or gas recovery, the presence and use of a biocidally-effective amount of a sulfamate-stabilized, bromine-based biocide with injection water that is to be used in the system or process such that bromine-based biocide is present in at least a portion of the system and/or in at least a portion of the water in the system. A composition especially adapted for use in secondary oil recovery operations, is comprised of seawat er with which has been blended a biocidally-effective amount of a sulfamate- stabilized, bromine-based biocide.
