1. A method of reducing salinity of salt-containing material (SCM) generated during production of hydrocarbons from a reservoir, the method comprising:
introducing the SCM into a wash system comprising at least one mixing tank;
introducing feed water into the wash system in a countercurrent flow relative to the SCM;
mixing the SCM and the feed water in the at least one mixing tank to produce brine and a washed SCM;
discharging washed SCM from the wash system, the washed SCM having a lower salinity compared to the SCM that is initially introduced into the wash system; and
discharging brine from the wash system, the brine being generated from the feed water and having a higher salinity compared to the feed water.
