To extract crude oil from the depths of the earth, it is necessary to dig deep wells, which may cause the walls to collapse and cause a lot of damage. For this purpose and to create strength in the wall of the well, drilling mud is used, which includes bentonite, barite, xanthan gum, etc.

Drilling starch

High humidity, pH changes, multiple corrosions, etc. can cause drilling mud to become loose. Drilling starch, which is obtained from agricultural products such as potatoes, wheat, etc., can eliminate the loose and jelly-like state of drilling mud by absorbing water and create sufficient strength.

Starch is a type of powder that belongs to the group of polymer materials and transforms the materials used in the walls of the wells from a loose and jelly-like mud into a complex mixture of liquids, solids and chemicals. Iran has many potato fields and is able to produce millions of tons of this product every year. If starch is extracted in sufficient quantity, the country can be freed from the import of all kinds of drilling mud.
