Inhibiting reservoir souring using a treated injection water

A process for inhibiting souring in a hydrocarbon reservoir comprising:

• providing a reservoir containing a hydrocarbon and a well in fluid communication with said reservoir;
• providing a feed water including a plurality of phosphorous constituents and a sulfate-containing species, wherein said feed water has an elevated phosphorous concentration and an elevated sulfate concentration;
• and
• removing at least some of said phosphorous constituents and at least a portion of said sulfate-containing species from said feed water to produce a treated injection water, wherein said treated injection water has a reduced phosphorous concentration less than said elevated phosphorous concentration and a reduced sulfate concentration less than said elevated sulfate concentration.

• providing a reservoir containing a hydrocarbon and a well in fluid communication with said reservoir;
• providing a feed water including a plurality of phosphorous constituents and a sulfate reducing bacteria, wherein said feed water has an elevated phosphorous concentration and an elevated sulfate reducing bacteria concentration;
• and
• removing at least some of said phosphorous constituents and at least a portion of said sulfate reducing bacteria from said feed water to produce a treated injection water, wherein said treated injection water has a reduced phosphate concentration less than said elevated phosphate concentration and a reduced sulfate reducing bacteria concentration less than said elevated sulfate reducing bacteria concentration.
