Abstract
A modified high density brine for use in subterranean drilling and completion operations. The modified high density brine includes a heavy brine and the addition of high density particles. The resultant modified high density brine eliminates the need for toxic, corrosive, and costly ZrBror cesium formate additions or other ionic additives to boost the density of the modified high density brine to more than 14 lbs./gallon.
