Using Bi-Fuel System

to Reduce Emissions

Supplementing the use of diesel with natural gas in a bi-fuel system allows Crew to operate equipment in a more efficient, cost effective, and sustainable way. By working with our service providers, Crew has been able to utilize specialized bi-fuel equipment on its well sites during completion operations. Specifically, powering pressure pumpers, typically the largest consumers of diesel during our completion, with readily available natural gas instead of conventional diesel fuel.

The benefits of natural gas delivery to well sites go beyond pressure pumpers though, as cold winter temperatures necessitate superheaters to prevent on-site water from freezing. As with pumpers, these superheaters typically burn diesel fuel for power, but new equipment sourced by Crew enables natural gas to again be utilized for this purpose.

  • Between 2019 and 2021, this use of a bi-fuel system has enabled Crew to realize decreases in GHG emissions of 2,486 tCO2e due to the cleaner burning nature of natural gas when compared to diesel.
  • The reduction in nitrous oxide, a powerful greenhouse gas 298x as potent as carbon dioxide, has been reduced by over 88% through natural gas substitution.
  • Self-sourced natural gas that has been supplied to well sites from installed pipelines allows Crew to recognize a cost reduction for fuel, as natural gas is much cheaper than diesel when comparing $/MJ.
  • Emissions associated with transport of fuel also decrease with natural gas, as it is transported by pipeline, which emits far fewer emissions than diesel being transported by truck.
