Evaporation Rate From Waste Pits

One of the first things any estimate will need is the location of the proposed pits on the surface of the planet, the average rainfall at that location, the humudity, the ambient temperature range, the wind speeds, and so-on. Compare then with commercial salt production facilities for a first-guess, and then carry out small-scale field trials near the proposed facility. On completion of the trials, then do a scale-up with commercial constraints in mind.

Unless there's any other way?

Many thanks for your reply! I was aware that such details will be required, but I was mostly wondering that once all those details are available, what method/model can be then used for the estimation? Do you perhaps know of any journal or book that details that science behind this? Many thank!

As PWSlack says, this needs much, much more detail. You aren't just evaporating water. You are evaporating water that is mixed with many solids that will impeed the evaporation of the liquids.

Agitation may also be required, depending on how long you can wait.

Don't understand where you came up with 11000 barrels? A 8" diameter finished hole would place that volume of water over 100 thousand ft deep. Even at surface diameter bit size of 24 inch places it at 14 thousand plus. I do understand that all drilling operations lose water. Dispersement into the ground and hitting voids some of which can't be predicted. But that's a lot of fluid and you plan to have it left over to evaporate off.

And there is no reason most of the fluid can not be reused. Unless you are going to drill all the wells at the same time.

After a few days in the holding ponds to let the sediment settle out. Pump it out and reuse it.

If you are simply trying to measure evaporation rates then install a test pit and put a laser mounted on a heavy weight, fulcrum and a target 100 meters away to increase sensitivity. With a system like that you can watch the water etc. evaporate.

If you can set up connecting pipe from one pit to the next at the top of the pit, you can use sedemintation to help you 'clarify' the water in each pit which should make the last pit in line evaporate much faster than the first pit.

Normally, the drilling wastes (cuttings) volume is around 2,5 times the hole volumen,

If the mud used is polymeric base, could be more practical to coagulate and floculate using the Z potential and the apropiate floculant polymer, in order to get drier solids using centrifuge or geotube
