· Rheological properties of limestone slurry hinder its further free transport in the pipeline due to generated flow resistance. To improve this state of affairs, chemical treatment of drilling fluid, could be applied, of which the main task is to give the slurry properties suitable for the conditions encountered in hydrotransport.

· Limestone is a sedimentary rock. It’s made up of calcium carbonate. It forms from the shells and bone fragments of organisms, meaning it has lots of fossils. It’s a great building material and is used for flooring, walls, and decoration. Limestone often has fossils that give us a glimpse into the past.

· Properties of Limestone: Calcium Carbonate Content: Limestone is primarily composed of calcium carbonate (CaCO3), which gives it its fundamental chemical composition. Color: Limestone can vary in color, from white and gray to yellow, brown, and even black. The color often depends on impurities and mineral content.

Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place
