Can we use sea water in scale clean out job?
(OP)
We used filtered fresh water with NH4CL for circulate in Coil tubing job, however it's very expensive and consume time much. So we would like to use SEA WATER instead with any chemial additive, ex NH4CL to prevent clay swell(ion exchange), Bioside to kill bacteria, filtered to prevent fine particle, but wht about ion in sea water? can we treat it?
And other tough ques is "Is SEA WATER really harmful to the formation??"
Appreciate for any opinions

I believe that you've got the barium and sulphate mixed up as to where they derive. I have extensive North Sea experince with formation water barium (up to 5000 ppm) and seawater injection for pressure support, which is why we lost early wells that were produced and why the company that I work for developed the sulphate removal technology with nanofiltration (you couldn't remove all the ions due to breaking down of the clays and causing fines migration).
