Abstract. Barium sulphate (BaSO 4) scaling is a known issue but still an unresolved problem in the petroleum and geothermal industries. It can cause severe damage to the wellbore and surface facilities. Prevention of scale formation is the technically and economically advantageous solution to apply.Web
A barium X-ray is a radiographic (X-ray) examination of the gastrointestinal (GI) tract. Barium X-rays (also called upper and lower GI series) are used to diagnose abnormalities of the GI tract, such as tumors, ulcers and other inflammatory conditions, polyps, hernias, and strictures. The use of barium with standard X-rays contributes to the ...Web
