Dear Pak Frank,

I wish we can do that, do something for our own small people. Potassium brines or potassium mud are the most widely accepted completion fluids / mud system for shale sensitive formations, especially the hard & brittle shales. K+ ions will attach to clay surfaces & improve stability to shales which is exposed to the completion or drilling fluid. During drilling, the ions also help hold the cuttings together & minimizing dispersion into finer particles. Na+ ions (from NaCl sodium chloride) unfortunately counteracts the benefits of K+ ions. That’s why it should be minimized by using fresh water instead of sea water for make-up water.

Cost wise, KCl & NaCl generally are the same. For offshore operations, if other issues permit, sea water is the most economical solution. The NaCl doesn’t come from any salt farming when it’s available around you for free. Most of the operators are selecting brines based on the availability & logistically makes sense.

Hi Pak Doddy

Firstly, I should have thank you for your great response, but my concern is if we can put NaCl to take the place of KCl because, I do think ( to my short knowledge ) we haven’t got a plant here in this country to produce such product to make potassium brine – do we ?

Secondly,by learning at your scientifical argument and know where you are standing now technically I have no doubt about – that is superb answer, reminds me to my old days in that expertise, but again logistically in term of cost by keep using KCL is my concern.
