Petrochemicals

In an oilfield the oil is generally mixed with gas, production water and contaminants. In the oil treatment plant the gases, water, and contaminants are separated from the oil. Then the stabilized oil is ready to be shipped by oil tankers.

Gas Treatment Chemicals

The gas separated from the oil is gathered in a gas plant where it is dehydrated and processed to recover the heavy fractions and to remove sulphur compounds. The treated gas can then be transported by pipeline.

Drilling Fluids

Drilling Fluids (often referred to as Drilling Mud) fill many functions in the successful drilling and completion of an oil or gas well.

Cementing Chemicals

Cementing additives are used during and after the drilling function, when casing strings need to be cemented into the well bore.

Production Optimization Chemicals

The Production Optimization division consists of three sub-domains, which cover the different types of production optimisation treatments that DOSAS can provide: Stimulation, Remediation, and Prevention.

Production & Refinery chemicals

An oil refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil,kerosene, and liquefied petroleum gas.
