WHAT IS FRAC-FLOWBACK?
Frac-flowback is the recovery of fluid used in the high-pressure hydraulic fracturing process to stimulate oil and/or gas production in a well. Typically, there is formation water, oil, and gas recovered along with the frac fluid.
Accelerated frac-flowback is the recovery of frac fluid from a well as quickly as possible while bringing oil and/or gas production to the market immediately.
HOW DOES JJ TECH DO IT?
We call it, FRAC-EVAC. We achieve faster frac-flowback using a patented JJ Tech Jet Pump. The jet pump is set in the tubing string above a packer, which is set just above the perforations. Power fluid (water) is injected down the tubing through a nozzle. The power fluid and produced (frac) fluids are then combined in the throat (the Venturi Effect) and return up the tubing-casing annulus.
The power for FRAC-EVAC is provided by JJ Tech’s ULTRA-FLOW production system. This patented process combines the JJ Tech Hydraulic Jet Pump with a powerful diaphragm surface pump by Wanner Engineering Inc.
This award-winning diaphragm pump has no seals and is packing free, unlike the conventional triplex plunger pump. Not only does the seal-less design reduce downtime and maintenance, it is also an environmentally sound option, preventing oil and saltwater leakage. The Wanner T100K Diaphragm Pump is capable of 1550 BPD at 3000 PSI.
WHAT ARE THE RESULTS?
Case studies prove that FRAC-EVAC can remove large volumes of fluid and bring production to market in a fraction of the recovery time than a conventional rod and tubing system can achieve.
Other advantages of FRAC-EVAC include:
- Rapid frac fluid recovery helps prevent formation swelling, which can reduce permeability.
- The JJ Tech Jet Pump can produce high volumes of fluid (up to 4500 BPD) and frac sand.
- Production rates are easily adjusted for a controlled flowback.
- Gas can be brought to market immediately.
- No back pressure is put on the formation (as is with nitrogen).
- Proprietary software calculates PBHP based on production volumes and injection pressure.
