Energy efficiency in the oil and gas sector primarily relates to the efficient use of energy – heat and power – in industry segments including, but not limited to, upstream and offshore oil and gas production, processing, transmission, and refining. Efficiency may be defined in different ways depending on the process or equipment under consideration; however, it may be generally defined as the energy of the outputs (e.g., fuels, chemicals, energy – heat and power) of a process or facility divided by the energy of all inputs (e.g., fuels, chemicals, energy – heat and power)

Energy-efficient oil and gas processing begins with efficient facility design. Central to this are integrated design practices. These consider the facility as a single system and aim to minimize overall energy use across the expected range of operating conditions, while maximizing production
