Crude oil
Crude oil is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various
molecular weights and other liquid organic compounds, that are found in geologic formations beneath the
Earth's surface.
The flash point of crude oil is low, typically below ambient temperature.
Our four-stroke medium-speed engines are well proven in operation on crude oil taken directly from oil wells
and conditioned on site.
Exploiting crude oil to feed the large consumers involved in oil and gas exploration and production is both an
economical solution and saves the considerable CO
their transport via pumping stations from and to the oil field.
