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 scales in geothermal installations are a highly unwanted effect of circulating deep saline fluids. They build up in the reservoir if supersaturated fluids are re-injected, leading to irreversible loss of injectivity. A model is presented for calculating the total expected barite precipitation. To determine the related injectivity decline over time, …

adopted for 4.1-SG barite when it was sanctioned in 2010. The increasing demand for drilling fluids and dwindling reserves of high-quality barite has made sourcing a cost-efficient 4.2-SG barite extremely challenging over the past few years. With the acceptance of 4.1-SG barite for some non-critical operations, barite supplies were extended for a

Barite (BaSO 4) precipitation is one of the most ubiquitous examples of secondary sulfate mineral scaling in shale oil and gas reservoirs. Often, a suite of chemical additives is used during fracturing operations to inhibit the accumulation of mineral scales, though their efficacy is widely varied and poorly understood.

Barite is a mineral composed of barium sulfate (BaSO 4). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...
