ENERGY CONSUMPTION IN THE OIL EXTRACTION SYSTEM OF ECUADOR
was obtained from Petroamazonas EP´s
inventory.
Electricity consumption in each oil block
was calculated by fuel type (petrol, diesel
and gas) and the generation technology
used (thermal). The data utilized was from
CELEC EP and PETROAMAZONAS EP.
The energy payback rate was calculated
from the audited oil production and
energy consumption. EROI = Amount of
energy delivered by a process / amount of
energy used in the same process.
*For the energy payback calculation, only
use electricity energy consumption (This
energy was 82% of total consumption).
** The unit of energy is the Joule.

Electricity generation in the oil blocks responds to thermal systems
that use different fuels like oil, diesel and gas.
Crude oil is consumed directly in each block before posting
and delivery to the State.
Diesel that is produced in small refining plants built by each
operating company (there are 3 topping plants) or diesel
purchased to the public company EP Petroecuador is
consumed.
Gas obtained from the oil extraction after a treatment
process is consumed.

In the oil system there is an energy component that is not accounted
for in national inventories which is the consumption of energy in the
extraction processes. In 1012, the total energy consumption of the
24 oil blocks in operation in 2012 was 44.6 PJ. This energy was
used in different processes like 1) the separation of water and gas
Associated With The extraction of crude oil 2) pumping systems for
transportation 3) for suction of oil and water reinjection and 4) to
supply electricity to the oil camps.

The energy payback calculation to oilfield in Ecuador average was
29.25. There are oilfields with higher energy consumption and is due
to several factors: the characteristics of the oil reservoirs, extraction
infrastructure and technology, energy system and the formation
water amount.
