Products & Services
For highly sensitive and low pressure reservoirs, nitrogen is used to reduce reservoir damage, fluid loss and increase flowback efficiency. Nitrogen assisted fraccing technology has been widely used in many industries, such as tight oil&gas, CBM. Orion has been committed to the research of nitrogen assisted fraccing technology and its onsite operation ,nitrogen equip was introduced in 2013 which facilitated Orion’s advanced position in the industry in China.
