How to Select a System That Matches Your Application and CAPEX Budget
Hydraulic jet pump systems are becoming increasingly popular in the oil and gas industry. While all jet pump systems operate in basically the same manner, jet pumps systems can vary in cost. For this reason, it is important to know and understand your application before asking for a system quote. Doing this will ensure the system has the capabilities you need, while enabling you to compare its price against other systems.
Jet Pump System Design
A jet pump analysis should be done on your well in order to determine several things:
- What is my primary objective?
- Unload frac fluid and place on permanent form of lift
- Test well to properly size the required form of permanent lift
- Replace existing form of lift to avoid excessive workover costs
- Try a different system for better results
- Is a jet pump system the right form of artificial lift for your application?
- What type of downhole configuration should be used?
- Conventional
- Concentric string design
- How much horsepower will be required for my application?
- Surface pump size affects initial cost
- Horsepower usage affects ongoing operational costs Lease Operating Expenses (LOE)
Surface System Design
Planning the right surface configuration is important for the long-term success of your jet pump system.
- What will be used for a power fluid source
- Existing stock tanks
- Frac tanks
- Power fluid vessel
- Power Source
Power Fluid Pump System
The surface pump is the workhorse of a jet pump system. Having the right type of pump along with the proper filtration, metering, and safety systems in place ensures the long-term functionality of a jet pump system.
- Surface Pump
- Conventional triplex plunger pump
- ~95% mechanical efficiency
- Packing wear necessitates replacement
- Plungers require constant lubrication
- Multistage centrifugal pump (H-Pump)
- ~60-65% mechanical efficiency
- Thrust chamber maintenance
- Hydra-cell diaphragm pump
- ~90% mechanical efficiency
- No packing
- Plungers don't require external lubrication
- Starter Panel
- Soft start
- Low up-front cost
- High usage cost due to pressure regulating valve (bypassing pressurized fluid)
- Variable frequency drive
- Higher up-front cost
- Lower usage cost as no fluid is bypassed (No waste of energy)
- Filtration
- No Filtration
- Filtration is needed - pumping through small orifice in Jet Pump
- Y-Type or basket type strainer
- Low cost, but time consuming to clean, involving unit shutdown
- Duplex basket type strainer
- Higher Cost, but can be cleaned without production shutdown
- Pulsation Control
- Suction stabilizer
- Discharge dampener
- Pump discharge flowmeter
- Confirms pumped-fluid rate
- Pressure transmitter
- Works in conjunction with Proportional Integral Derivative (PID) loop on Variable frequency drive
- Safety System
- Pump discharge pressure
- Electronic
- Mechanical PSV
- Pump suction pressure
- Pump oil level
- Vibration
Jet Pump Design & Optimization
During the life of a well, conditions can change. Having access to and understanding how to maximize the efficiency of your hydraulic jet pump system can reduce ongoing lease related OPEX.
- Initial System Design
- Collecting well data is crucial
- Determines surface pump size (hp required)
- Determines initial pumping configuration (starting point)
- Optimizing for maximum efficiency
- Initial production results confirm the correct pump assembly
- JJ Tech jet pump analysis software can maximize hp usage
- Conserve energy
- Maximize production
- Gauge Carrier
- Tool can confirm downhole temperature/pressure
- Will confirm jet pump analyzer’s calculations
