The pelagic barite precipitation in the seawater column is tightly associated with the biological pump, and thus the barite Ba isotope composition (δ 138/134 Ba) has been advocated as a novel paleo-productivity proxy. However, pelagic barites in sediments are susceptible to diagenetic processes that may modify primary δ 138/134 Ba signals …

Barite scale is the most common oilfield scale in oil and gas wells. Barite scale removal still represents a challenge to the oil and gas industry because of its low solubility in mineral acids such as HCl. Chelating agents such as diethylene triamine pent acetic acid (DTPA), ethylene diamine tetra acetic acid (EDTA), and hydroxy ethyl …

He said the first contract was about barite mine in Herat city, spreading over an area of 5.7 square kilometers and the contractor would invest 5,990 million dollars. He added that the government's share in this mine was 50 percent. Barite is a type of mineral that is found in oil and gas wells and is abundant in the country.

Barite saturation indices (SI = log ion activity product/solubility product) are significantly reduced in all experiments at higher salinity due to a reduction in Ba 2+ and SO 4 2− ion activities. Under optimised co-precipitation conditions (0.22 mM Ba 2+), similar barite saturation indices of 2.2 and 2.4 were observed at 0.3 and 3 M NaCl ...

Apart from barite, the barite extraction procedure may have dissolved minor amounts of detrital minerals, as seen from the minor amount of Al detected in the NH 4 Cl-leachates (Fig. 2; Dataset S1). Although this detrital phase is quantitatively negligible, it might introduce errors to the calculated barite Sr/Ba values.

Abstract. Barite is one of the most common weighting materials used in drilling fluid for deep oil and gas wells. Consequently, the main source of solids building the filter cake is the weighting material used in drilling fluids 'Barite particles'. Barite is insoluble in water and acids such as HCl, formic, citric, and acetic acids, as well as the barite has …
