PROJECT OVERVIEW
8/3/2019 Quest CCS Project
http://slidepdf.com/reader/full/quest-ccs-project 2/10
“The Quest CCS project wouldcapture and store more than onemillion tonnes of CO2 each year.That’s like taking175,000 NorthAmerican vehicles off the road.”
— Peter Voser, Chief Executive Officer, Royal Dutch Shell plc.
CARBON CAPTURE AND STORAGE (CCS): ONE OF THE PATHWAYSTO REDUCE CARBON DIOXIDE (CO
2) EMISSIONS
To continue meeting the world’s growing energy demand, while reducing greenhouse gas (GHG) emissions, severa
pathways must be pursued. CCS is one of the key pathways that Shell is progressing along with energy efficiency, low CO2
fuel options, and advocating more effective CO2
regulations to reduce global GHGs.
Shell Canada Energy, on behalf of the Athabasca Oil Sands Project, a joint venture among Shell Canada Energy (60 per cent),
Chevron Canada Limited (20 per cent) and Marathon Oil Canada Corporation (20 per cent), is advancing Quest. Quest is a fully
integrated CCS project, meaning it would capture, transport, inject, store and monitor CO2. Over one million tonnes of CO2 pe year would be captured per year from the Scotford Upgrader. This 98% pure CO2
would then be transported safely by pipeline
to an injection location north of Shell Scotford and stored permanently more than two kilometres deep under thick layers o
impermeable geological formations.
PROJECT STATUS & PLANS
Shell has conducted feasibility studies and drilled test wells to outline development options. Several important steps are stil
needed before a final capital investment decision is taken on Quest. That investment decision will ultimately depend on a
range of factors, including the outcome of a structured consultation process with stakeholders, the results of appraisa
activities and detailed integrated studies, as well as the ability to meet all regulatory requirements. Construction would only
begin after all of these aspects have been addressed successfully, with the aim to start operations around 2015.

Shell's highest priority is safety. Shell is involved in development work for numerous CCS projects around the world,
and can bring forward the resources required for the successful design, implementation and operation of a safe
integrated CCS project in Alberta. Shell will use industry best practices to design, construct, operate and maintain
the Quest facilities to meet the highest safety standards.
Design: Shell will use its industry-leading expertise in subsurface geological mapping of deep reservoirs to ensure
that the proposed CO2
storage formation meets all the requirements for safe and permanent storage of CO2.
Response Plan: Shell has an existing Emergency Response Plan (ERP) for the Scotford Upgrader. If the Quest CCS
Project is approved, the construction and operation of the new infrastructure will be incorporated into Shell’s existing
ERP. Residents and public land users near the pipeline will participate in a separate consultation process specifically
for developing this ERP.
Pipeline Safety: Thousands of kilometres of CO2
pipelines are in safe and reliable operation in North America
today, mostly in the United States. Shell is familiar with both the construction and operation of CO2 pipelines, which
have been in use since the early 1970s in the enhanced oil recovery industry in Texas and New Mexico. The pipeline
for Quest will be designed to meet the latest safety specifications. In the unlikely event of a leak, valves will be
closed automatically to isolate the section of the pipeline, minimizing any release of CO2. In addition, the pipe-
line will have routine aerial surveillance, gound surveillance and Shell will cooperate with other pipeline
owners who share the same utility corridor.
Injection Safety: Particular attention is paid to well design, operations and abandonment for CO2
injection
schemes. For Quest, the injection of dry CO2, and the selection of corrosive-resistant casing and cement materials
will be used to ensure the long-term integrity of the wells. During operations, well tests and monitoring will be
conducted. Injection pressures will conform to regulatory requirements and be maintained at levels that ensure
the injection formation and overlying seals maintain their mechanical integrity. Once injection stops, a closure
period of continued monitoring will take place and then wells will be plugged and abandoned to ensure the
long-term containment of the stored CO2. These construction techniques and operations will ensure protection
of shallower oil and gas reservoirs, and usable groundwater and the health and safety of local communities.
Safety in Storage: Safety in storage is based primarily on adequate data collection and analysis to character-
ize and select the preferred storage formation and injection and monitoring site. In the case of Quest, the
proposed injection formation is about 2 kilometres deep and located below layers of thick, impermeable, continu-
ous seal rocks, which will prevent CO2
from escaping. The CO2
will be trapped within the tiny pore spaces
between the grains of the sandstone rock formation and by dissolving into the brine of the saline aquifer. Shell
will use its industry-leading expertise in subsurface geological mapping to ensure that the design and operation
of the proposed CO2
storage formation meets all the requirements for safe and permanent storage of CO2.

Scotford Upgrader Amine Unit & Compressor
Carbon capture and storage (CCS) is a process that uses proven technologies to capture, transport, inject, store and monitor CO2 in geological formations deep underground. Quest will use existing technology that has been used safely and reliably in otherapplications in Canada and elsewhere around the world.
Capturing and compressing CO2 from the Shell Scotford Upgrader
CO2
will be captured from three hydrogen manufacturing units at the Scotford Upgraders.
An absorber vessel will use an amine solvent to capture the CO2
from the process stream.The CO
2will be released from the amine by heating.
CO2
will be compressed and dehydrated into a dense fluid for safe pipeline transport.
The CO2
fluid will be transported by pipeline to the storage site.

The facilities at Scotford will capture CO2
from the upgrader’shydrogen plants where the CO
2will be separated and
compressed into dense fluid, allowing for pipeline transpor tation.
The CO2
will be transported by pipeline (16 inches in diameter)from the Scotford Upgraders to injection location(s) within 100 kmfrom Scotford. The pipeline runs north from Scotford, following theexisting rights-of-way wherever possible. Safety, landowner input,environmental, geographical, and technical issues will all be takeninto consideration to determine the final route.
Shell will contact landowners and community leaders to discussand gather input about the proposed pipeline route, surveys,construction and reclamation activities.

STORAGE
Shell proposes to inject the CO2 2 km (2,000 m) underground into the
deepest saline aquifer formation in
Alberta. This formation, known as the
Basal Cambrian Sands (BCS), is
approximately 900 m deeper than the
hydrocarbon deposits in the area and
some 1800 m deeper than the groundwater.
SEALS
There are multiple, impermeable shale and salt sealing
rocks above the storage formation that ensure the injected
CO2 remains trapped deep underground.

Several types of rock formations are suitable for CO2
storageincluding saline aquifers and deep porous rock formationscontaining naturally occurring salt water. To obtain the highestlevels of CO
2storage containment and capacity, the most
suitable formations are usually selected at depths of 800
metres or more, where pressures and temperatures of the rockkeep the injected CO
2fluid in a dense phase. The identifica-
tion, assessment and development of a suitable storage forma-tion on the basis of rock characteristics of capacity, injectivity,containment and monitoring involves proven technologies andpractices used by the petroleum industry over many decades.Shell has used this experience to conduct appraisal and studyactivity over a region around Scotford and has identified theBasal Cambrian Sand (BCS) and the multiple overlying layersof continuous impermeable seals as the preferred storagesequence in the area.
Several geologic storage projects have already successfullystored millions of tonnes of CO2
for many years, withoutdetectable leaks. Three large-scale CCS projects have beenin operation for over 5 years or more and many new projectsare planned for start-up in the coming years. One project hasbeen operating in the Weyburn oilfield in Saskatchewan since2000. This project uses a pipeline to transport CO
2captured
near Beulah, North Dakota and then injects it into the Wey-burn field for enhanced oil recovery. The In Salah project inAlgeria extracts CO
2from produced gas and injects it back
into the ground, and the Sleipner CCS project in the Norwe-gian North Sea injects CO
2for storage in a saline aquifer.
Shell now plans tocomplete the appraisalwell, geophysical datagathering and studies to confirm the technical suitability of asite for injection, storage and monitoring north of Scotford.
The appraisal well program will also include small flow teststo further assess injectivity rates. Seismic survey data will beused to further assess the location of wells.
Monitoring
Quest will use measuring, monitoring and verification (MMV)technologies and systems to ensure the storage site performsas expected. This will require data collection and analysis notonly during CO
2injection but also before and after the startup of
injection. The evaluation of potential MMV tools andsystems is an integral part of the ongoing appraisal and
technical study work of a storage site now being planned. Inaddition both the CO2
capture and pipeline facilities will bepart of the monitoring program to ensure the CO
2is handled
and stored in a safe and secure way.
All this work underpins the responsible implementation of CCSin Alberta – which is gifted with some of the most promisinggeology for CO
2storage in Canada.

QUEST: PATHWAY TOWARDS MORE ENERGY AND LESS CO2
Introducing CCS in Alberta will create jobs, stimulate economic activity, establish initial infrastructure and, most impo
tantly, support Alberta and Canada’s drive to address climate change as part of a global effort. In that, the experienc
gained locally through the early implementation of CCS demonstrators such as Quest will prove invaluable in develop
ing the capability and the capacity to enable industrial facilities to reduce greenhouse gas emissions.
Shell is developing and implementing the Quest CCS Project in an environmentally responsible and sustainable way
Shell will work with landowners, the community and appropriate federal and provincial agencies to identify the bes
actions for minimizing any disturbance to landowners, the environment and surrounding communities. Shell will adhere
to all applicable regulations and will conduct the necessary environmental field studies.
The studies will identify areas of concern such as soil composition, vegetation, wildlife, endangered species and bodie
of water.
PUBLIC CONSULTATION
Shell has operated in the Scotford area for almost 30 years, and has a long history of community relations and commun
cation in the region. Shell strives to ensure that project plans adequately address the concerns of local communities.
Shell will undertake a comprehensive public consultation program in support of the Quest CCS Project. Shell believes i
the timely dissemination of information and collaborative approach to discussing concerns with stakeholders.
Shell encourages the public to participate in the consultation process to ensure that we are able to adequately identify
understand and respond to issues and concerns raised by stakeholders.
