Drill reagents are used to alter the properties of chemical drill muds in the oil and gas producing industry. In particular, chemical drill reagents can increase the viscosity of non-dispersed water-base well muds. These substances are added to muds at the factory or immediately before drilling. Water-base drill muds require the addition of chemical drill reagents for greater content of solids and lesser liquid losses. This reduces the probability of formation damage and increases the rate of penetration.
Polymers of any origin have a series of peculiar features. Synthetic polyacrylamide, for instance, increases mud viscosity (including thixotropy) and filtration characteristics. Natural xanthan gums are added to polymer-based and high-salinity drill muds as drill reagents to increase mud viscosity levels.
PROCESSING AND USAGE OF LIGNOSULPHONATES
After the separation of yeast, sulphite-cellulose liquor mostly contains lignosulphonates, aside from certain amounts of cellulose fibres and yeast cells. Cellulose fibres are separated using filtering machinery (vibrating sieves, drum filters, sloping sieves). Yeast cells are removed using additional exhausting separators.

One of the production-related problems most commonly encountered in any industry is the issue of metal corrosion, which renders expensive equipment inoperable. Metal corrosion is the process of metal ion oxidation, which eventually leads to its destruction. The issue of metal corrosion is especially pressing in the chemical and oil processing industry, where equipment is often in regular contact with aggressive acidic media that speed up the process of corrosion to a considerable extent. The solution to this situation lies in the usage of metal corrosion inhibitors, which inhibit the process essentially.
