Heavy Oil Capability and Experience

As the world’s oil resource is getting heavier, producers worldwide must adapt to the replacement of existing depleted light oil reserves
and production with heavy oil and in•situ bitumen production. WorleyParsons MEG is a leader in this area with nearly 40 years of experience.
WorleyParsons MEG provides expertise in fluid handling and measurement, emulsion characterisation, interface fluids treatments, waxy
crude and asphaltine issues, sand cleaning, desanding equipment for heavy oil, heavy oil transport, source•water selection, source and
produced water treatment and Enhanced Oil Recovery (EOR) projects. WorleyParsons MEG is at the forefront of new technology having
participated in numerous research and development and pilot plant projects, including field•scale upgraders.
Significant achievements include:
• Design and Installation of the “first ever” Zero Liquid Discharge (ZLD) water treatment system for Thermal I Heavy Oil Project.
• Development of a newly patented Produced Water Treating process that eliminates the need for lime softeners.
• Assisted in the development of small scale gasifier for the use in thermal heavy oil operations.
• Utilized a combination of desalination RO and MVC resulting in close to al 100% water re use system in a large Middle East Steam
 Injection project.
• Increased performance of a WLS system to 20% above the design rating capacity. The experience and agility of key technical personnel
assigned to all projects is the cornerstone of our project success. Our understanding of heavy oil and in•situ bitumen assists in effective
field development and enables our customers to maximize the value of their reservoir assets.

300+ Heavy oil projects

Thermal Project Experience
Each year producers go after oils and bitumen of lower and lower gravity. Steam and steam solvent processes are bringing increased volumes to market. WorleyParsons MEG brings new and current technologies to bear on the problems of heat integration, water conservation and product handling.
WorleyParsons MEG understanding of the heat exchange challenges inherent to production fluids from these viscous oil reservoirs
allows us to better specify our exchange equipment and to help our customers manage both heat transfer and cleaning frequencies without over investment of capital. Our capability extends to working with our customers to develop and integrate online heat exchange fouling monitoring into their maintenance planning. The handling of water within thermal heavy oil facilities is a precise speciality that can be
a major roadblock to a project’s success. Increasing population density and environmental issues have brought new pressure to manage water within these projects to tighter specification, with reduced make•up and disposal rates. The capability of our experienced
team of water chemists and engineers has led to the development of a new standard in internal water management within thermal plants.
Lower oil gravities bring with them the challenges of increased viscosity, higher pour•points, increasing sulfur content and emulsions with water and sand that are harder to separate. Effective equipment and instrumentation design and specification is critical to project
success. WorleyParsons MEG has a proven track record of providing equipment with durability without excess and instrumentation that is robust and accurate.

Additional Capabilites
Conventional Heavy
WorleyParsons MEG has been an active participant in conventional heavy oil projects in Canada and around the world. From truck•in operations, CHOPS facilities, LACT units and conventional heavy oil treating plants, to greenfield developments exceeding 100,000 bpd in
heavy oil and 250,000 bpd in conventional oil, we have planned, designed and built facilities that are fit for our customers individual needs and circumstances.
Pilot Plants
WorleyParsons MEG has extensive experience in the design, construction and modification of heavy oil pilot facilities for SAGD, VAPEX, Co Injection, Thermal Solvent and field upgrading technology. Our experts specialize in adaptive and flexible solutions to assist our customers in the capture of information for commercial scale units and the demonstration of viable technology beyond lab•scale.
Produced & Source Water Treatment
Water can be as much of a challenge to handle as hydrocarbons. WorleyParsons MEG brings expertise in recycling produced water treatment for boiler feed water. Our specialists have lead the design of water plants using Warm and Hot Lime Softening, Mechanical Vapour Compression, Reverse Osmosis, Zero Liquid Discharge and Ion Exchange processes. We have demonstrated capability in de•oiling of produced water, treatment of make•up & disposal water, supply pipeline design and computer analysis of water compatibility.

Owner’s Engineering
WorleyParsons MEG can help customers reach their financial, operating, and technical goals. As Owner’s Engineer, we focus on
integrating our team with our customer’s, promoting a seamless flow of communication and progress.

Capability  Canada
Project: Firebag Stage 1 SAGD Commercial Plant
Customer: Suncor Energy Inc
WorleyParsons MEG completed a DBM, EDS, FEED and performed 120,000 manhours of detailed engineering for this new 5,560 m3/d Steam Assisted Gravity Drainage (SAGD) plant.
WorleyParsons MEG continues to provide engineering and procurement services for plant operations including small in•plant projects. The plant consists of facilities for source water supply, boiler feed water treating, steam generation and distribution, emulsion treating, bitumen storage, and produced water treating and disposal. Wellpads, distribution / gathering lines and interconnects to the oil sands plant are further integral components. Photo courtesy of Suncor Energy Inc
Project: Foster Creek Phase 2 SAGD Water Treatment Study
Customer: Ecana
WorleyParsons MEG was contracted by EnCana to carry out a comprehensive study to
compare the merits of HLS and WLS processes and associated equipment. The major
study items included an examination of the capital, the process chemistry on mixing the
various make•up waters; the plant mass balance and the investigation of design features
that would improve plant operability and reduce costs. Significant accomplishments
included the inclusion of a blend tank and heat exchanger upstream of the WLS to ensureconstant operating temperature for the unit.
Project: Mackay River Expansion
Customer: Petro•Canada
WorleyParsons MEG executed the FEED and detail design involving the retro fit installation of proprietary heat recovery technology at Mackay River Fields Pad. This was the first known installation of such technology. Other novel accomplishments included the study and subsequent installation of noise and vibration abatement equipment.

Project: Wolf Lake FEED 4
Customer: Canadian Natural Resources Ltd (CNRL)
CNRL plans to increase the production into the Wolf Lake Plant to 18,000 meters cubed/
day of 11° API, by constructing new field production facilities and steam plants at Primrose
East (PRE), and expanding production in the Primrose and Wolf Lake areas.
WorleyParsons MEG has been contracted to complete the FEED with a ± 20% estimate for
the new Wolf Lake 4 Plant with its associated additions and upgrades to utilities and offsite
