Heavy Oil

Heavy oil research
The Heavy Oil Technology Centre (HOTC) is Statoil’s first multi-national technology
centre and represents a significant commitment to invest in innovation that supports
improved hydrocarbon recovery and excellence in environmental performance from
extra heavy oil reservoirs in Canada and beyond.
The HOTC employs 60 researchers based
in Norway and Calgary with a mandate
to undertake research and technology
development that supports the company’s
heavy oil business worldwide with
particular focus on the needs of the Kai
Kos Dehseh (KKD) Oil Sands Partnership.
The HOTC team is responsible for
developing energy efficient and smart
solutions to enhance recovery of extra
heavy oil from challenging reservoirs
such as the Athabasca Oil Sands deposits
in Northern Alberta while reducing
environmental impacts for example
through reduced GHG emissions intensity
and water use.
HOTC has a global mindset and looks for
opportunities to expand on collaboration
opportunities already established with
research institutes in Canada, Norway,
and around the globe to support the extra
heavy oil innovation agenda.
Exploring technology options
• HOTC is developing concepts and
technologies to access and recover extra
heavy from more challenging reservoirs
in manner that is consistent with Statoil’s
focus on sustainable development. We
are developing advanced imaging and
monitoring technologies for improved
reservoir simulation models, to identify
the most promising locations for bitumen
production. A good understanding of
the reservoir, combined with leading-
edge drilling processes, will ensure that
Statoil produces the maximum resource
• Delivering continuous improvement to
the Steam Assisted Gravity Drainage
(SAGD) process through novel recovery
techniques such as solvent co-injection
which enhances SAGD recovery
efficiency and in-situ combustion which
is aimed at enhancing recovery after
steam injection opportunities have been
optimized. Such technologies have the
potential to increase overall yield and
reduce water and energy use intensity.
• Optimizing SAGD through the design
of advanced process controls and novel
methods that focus delivery of steam to
where it will have maximum impact will
reduce water use and carbon dioxide
emissions in Statoil’s operations..
• Designing improved water treatment
processes for surface facilities to reduce
chemical use, reduce the amount of
make-up water needed to generate
steam, and improve upon overall waste
management. Statoil’s goal is to recycle
more than 90% of the water we use.
• Investigating energy efficiency measures
ranging from waste heat capture to
renewable energy options will reduce the
carbon dioxide emissions resulting from
bitumen production.
• Developing new environmental
monitoring tools to detect the long-term
effects of SAGD operations on surface
water quality, and local flora and fauna,
will help Statoil to maintain its role as the
world’s most sustainable company.
Selected HOTC project highlights:
• The Oil Sands Leadership Initiative
(OSLI) Water Technology Development
Centre (WTDC) is a collaborative
project where several oil companies are
investing in the design, construction, and
operations of a state-of-art test facility
that will enable technical qualification of
emerging water treatment technologies
that have the potential to reduce
the overall water impact of SAGD
• A solvent co-injection (SCI) pilot
is being planned for the Leismer
Demonstration Plant for early 2013.
Injecting steam with condensate (a very
light hydrocarbon) into the reservoir
has the potential to significantly reduce
steam requirements (compared to
conventional SAGD) and increase yield,
with a corresponding reduction in CO2
emissions. SCI is one of many technology
developments carried out by HOTC to
fulfill Statoil’s ambition to sustainably
reduce CO2 intensity by 40% by 2025.
The scope of the climate challenge facing the world means that all players, including Statoil,
must consider whether they are doing enough, and whether they have the appropriate
means to reduce their emissions of carbon dioxide.
