Barium tests are used to help see the outline of various parts of the gut (gastrointestinal tract). These include the gullet (oesophagus), stomach, upper gut (small intestines) and colon (large intestine). Barium X-ray tests are done less commonly these days. Today we usually look into the gut with a flexible telpe ( endoscopy or …

Barite is completely insoluble in water as well as in various acids, such as acetic acid, lactic acid, hydrochloric acid, and formic acid. In this study, a novel method is introduced to remove the barium sulfate filter cake by introducing a new formulation of both oil-based and water-based drilling fluids. The new formulation can prevent fluid ...
