Oil production is a technically complex and multi-stage process that requires constant control and difficult analytical decisions. To enhance performance of oilfield equipment, oil companies use a variety of process fluids and chemicals which are selected by Gazprom Neft's Science and Technology Center’s oilfield chemistry engineers.
The STC experts know which methods and chemicals should be used to improve operational reliability of downhole and surface equipment; they also know how to manage reservoirs to maximize oil recovery from fields in different development phases.
The use of special inhibitors during well operation helps prevent deposition of inorganic salts or sediments that may reduce the well flow rate or cause equipment failure. Other chemicals prevent equipment corrosion caused by high formation temperature, pressure and presence of carbon dioxide, and help extend the service life of equipment and reduce maintenance costs.
Gazprom Neft’s Science and Technology Center never stops looking for and introducing new technologies that make oil production more efficient by taking into consideration specific features of each individual oil field. The STC specialists select the best chemical compositions for certain reservoir conditions and take part in designing new process fluid formulations.
The STC’s oilfield chemistry specialists are authors of a number of inventions created within its walls, including the technique of measuring surfactant concentration in process fluids.
