Jet Pump Technology: Old vs New
Efficiency:
SREP jet pump completions are often require only 25 to 30% of the power that a conventional jet
pump system would require
Surface Equipment:
SREP utilize patented diaphragm surface pumps skid packages for longevity and low maintenance
Our in-house design and fabrication provides optimized equipment solutions
Jet Pump Optimization:
Exclusive SREP jet pump software allows accurate analysis and system design optimization
Completion Design:
SREP focuses exclusively on jet pump completions and design – providing the highest possible
level of jet pump design solutions, tailored to each well application
SREP have a range of new patented jet pump completion solutions designed to expand the use and
performance of our jet pump technology
The SREP Jet Pump
• A proven oil pumping and / or dewatering system
• Highly scalable output range:
• 2 to 2000+ BPD
• Very efficient
• No downhole moving parts
• Sand handling capability
• No gas-locking issues
• Deviated / horizontal wells
• Can be installed in slimhole completions
• Continuous Corrosion / Scale / Paraffin control
• Pumpable / fishable carrier

Jet Pump Applications
Well Types Issues
Watered-out Gas Needs effective & aggressive dewatering process / issues with rod pumps and PCPs
Horizontal Oil / Gas Landing depth / conventional pump failures / horizontal depletion / prod rate / paraffin
Vertical Oil Pump failures & service costs / production rate
CBM Fines handling / pumps need broad performance band
Shale Gas Horizontal, multi-zone completions / post-frac dewatering needed / wet gas
Unconventional Oil Horizontal, multi-zone completions / post-frac clean-up / pump landing depth
Shallow Gas Economics / low rates w. solids transport
Gassy Oil Rod pump gas locking / PCP stator swelling & overheating
Gas with Condensate Can’t use PCPs / issues with rod pumps
Heavy Oil Sand abrasion / fines plugging / rod-float
SAGD Deviated wells / too hot for PCPs and ESPs
Cleanout Operations Dewatering / sand cleanouts
Oil Well Applications
Bakken Wells
Recent Well:
• Initial Production: 260 m3/D w. 60 HP
• Current: 100 m3/D – battery limited
First Well:
• Started February 2011 producing 75 m3/D
• Currently settling in around 40 m3/D
• Using 30 to 35 HP
Bakken Wells
Fairborne Energy Sinclair Operations Press Releases:
March 22nd, 2011:
“The first well (47% WI) in the winter program was fracture stimulated over 23 intervals and was
equipped for production using a jet pump, allowing for the production of significantly more fluid
than a standard pumpjack system. This well has been on production for 30 days and is currently
producing 200 barrels of oil per day.”
“The recent success from the enhanced completion technique, combined with further upside from
the use of jet pumps versus traditional pumpjacks has provided the first phase of success in the
development of Sinclair. With 60 (55 net) sections of land at Sinclair and 39 producing wells, the
Company has an identified drilling inventory in excess of 150 net wells.”
September 12th, 2011:
“Fairborne has been applying a number of new technologies to increase the value of the Sinclair
property. The first involves using burst port technology to increase the number of fracture
stimulations in horizontal well bores to between 25 and 28. The second is the application of Jet
Pump surface equipment which has been installed at two locations to evaluate performance. The
first jet pump well had an initial production rate of 200 barrels per day and after 170 days is still
producing at a rate of 140 barrels per day. The second well has exhibited an improving production
profile with a continued increase in oil cut and currently produces 55 barrels per day of oil. The
application of these technologies has led to an improved type curve with initial production rates
increasing from 60 barrels per day to 80 barrels per day, an increase of 33 percent.”
Crescent Point: Shaunavon
First Well:
• Initial production (IP): 160 m3/D
• Typical rod pump (IP): 70 m3/D
• Well cleaned up 1.5 times faster than with rod pump
