Towards Zero Harm with EIF

Zero Harm Goal


Conserving biodiversity


Limiting emissions and discharges


Key Environmental Aspects


Oil and natural components in
produced water


Chemicals in produced water and
discharges for drilling & wells


Emissions of NOx and CO2 from power
generation and flaring


Ballast Water


Waste


Acute discharges

Drilling Discharges Management

Drilling Fluid (Mud) & Cuttings


water based drilling fluid instead of
oil based drilling fluid, if possible.


Reuse of drilling fluids (batch drilling,
storage facilities)




Options for handling cuttings from
drilling

Management of Emissions to Air


Maximize the efficiency of power
generation


Electrical power from shore


Flare gas recovery system at several
installations


VOC recovery system on FPSO’s and
shuttle tankers for offshore loading


Low NOx burners in gas turbines (25
ppm NOx emission), since 1998


Catalytic cleaning (SCR) or gas motors
on some supply boats to reduce NOx

Management of Emissions to Air

Carbon Capture & Storage

Since 1998 CO2 separated
from natural gas at the
Sleipner field has been
injected in a deep saline
aquifer


this has
contributed to a 13%
reduction in CO2 emission
for the NCS
