Abstract: The present disclosure relates generally to methods for controlling souring in engineered systems, and more specifically to methods of controlling souring using chemical, physical, and combinatorial treatments of engineered systems to reduce hydrogen sulfide-associated souring in such engineered systems, such as oil reservoirs.

Abstract: A network communications system and method are disclosed. The system and method allow clients that are connected to separate networks interconnected using network address translation (NAT) to resolve names without the need to implement a split DNS system. The method provides for performing name resolution in a computer network, the network comprising one or more clients that communicate with hosts external to the network using network address translation. The method comprises: identifying traffic in the network that contain DNS messages, identifying DNS messages to be modified based on a network address translation table, and modifying a source or a destination address in identified DNS messages based on the network address translation table.
