water cooling
(OP)
Please, can anybody direct me to some materials / experiences for the case when during the well testing quantity of some 4 000 m3 of water/day has to be cooled from cca 85 C to 20 C before it is discarded to surface natural waters
Thank you
Thank you

A cooling tower or evaporation pond would work.
I believe your problem will be mineral deposites. As the water cools, you will precipitate minerals, if the water as them, an most produced waters do.

The heat works out to 2.6E8 kJ (2464 MMBTU/day or the equivalent heat of 2.5 MMCF/d of methane). I don't know any "quick and dirty" way to get rid of that much heat. If you have a bunch of surface water (i.e. offshore) then you could design a specific water-water heat exchanger to pump a few million m^3/day through one side to result in your produced water being at the right temp without the heat exchanger exhaust being too hot.
I recently designed an evaporation pond for 1/5 that much water and the pond surface was 75m X 75m. I don't think that you're going to be successful rejecting the heat to atmosphere.

Aside from capital cost, a problem you may run into is Calcium Carnonate/Barium Sulphate etc precipitating out in the heat exchangers as the temperature drops.
