ABSTRACT:
A process for inhibiting souring in a hydrocarbon reservoir provides a feed water including a plurality of phosphorous constituents and having an elevated phosphorous concentration. At least some of the phosphorous constituents are removed from the feed water to produce a treated injection water, which has a reduced phosphorous concentration less than the elevated phosphorous concentration. The treated injection water is injected into the reservoir via a first well and the hydrocarbon is produced from the reservoir via a second well. The process inhibits souring in the reservoir insofar as the treated injection water results in a lower level of souring in the reservoir over time than if the feed water had been injected into the reservoir.
