Practical considerations with Cesium Formate brine

27 May 2017 Dear colleagues,

We just held a fantastic 2-day CWOP for a deepwater,  'marginal HPHT' well completion campaign.

The intention is to use Cesium Formate (CsFo) brine during this activity.

The topic was thoroughly discussed: potential hazards to personnel, impact of elastomers, avoiding dilution (due to the ultra-high cost), the degreasing effect, ensuring maximum recovery (especially after gravel packing operations), filtration etc etc

But, beating the drum "you don't know what you don't know", what other practical considerations and solutions have our learned forum members encountered; those that fall into the category of "crikey, we never thought about that!".

Looking forward to your input.

Best wishes

Dave
