Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
