Studies of the energy return on investment (EROI) for oil production generally
rely on aggregated statistics for large regions or countries. In order to better
understand the drivers of the energy productivity of oil production, we use a
novel approach that applies a detailed field-level engineering model of oil and
gas production to estimate energy requirements of drilling, producing,
processing, and transporting crude oil. We examine 40 global oilfields, utilizing
detailed data for each field from hundreds of technical and scientific data
sources. Resulting net energy return (NER) ratios for studied oil fields range
from ?2 to ?100 MJ crude oil produced per MJ of total fuels consumed. External
energy return (EER) ratios, which compare energy produced to energy consumed from
external sources, exceed 1000:1 for fields that are largely self-sufficient. The
lowest energy returns are found to come from thermally-enhanced oil recovery
technologies. Results are generally insensitive to reasonable ranges of
assumptions explored in sensitivity analysis. Fields with very large associated
gas production are sensitive to assumptions about surface fluids processing due
to the shifts in energy consumed under different gas treatment configurations.
This model does not currently include energy invested in building oilfield
capital equipment (e.g., drilling rigs), nor does it include other indirect
energy uses such as labor or services.
