Intellectual Property

Patents, Licenses & IP Applications

We also take pride in our growing intellectual property portfolio.  Our multi level monitoring patents embed over 50 different technologies including electrical and chemical sensors, fiber optic and fiber Bragg sensors, integrated pump and sensor systems called “Intelli-Pumps”, advanced profiling technologies for groundwater production wells as well as cross over applications into environmental monitoring, agriculture, industry and geotechnical applications.


Within our IP portfolio is a relatively new, patented technology entitled “Selective Extraction of Fluids from Subsurface Wells” (US Patent 9,284,722, 2016). This forward thinking, outside the box suite of technologies combines every conceivable form of internal, hydraulic manipulation inside groundwater production wells at multiple depths along the well screen, with any type of groundwater treatment technology. Groundwater is hydraulically remixed or reconstituted inside the well in order to reduce mass transfer before reaching the ground surface.

At this point, reduced treatment is then combined with the hydraulically altered well to make the groundwater compliant.













In the best case scenarios, the change in well hydraulics leads to a more favorable geochemical discharge avoids treatment solutions entirely – saving billions of dollars for our customers as well as their rate payers.

However, not all wells can have water quality problems solved through only hydraulic manipulation. About 40% of the wells that we profile require a combination of hydraulic manipulation and reduced treatment.  This is where our process of Selective Extraction comes into play!
Using miniaturized down-hole diagnostics combined with the primary pump, our solution of reducing contaminant mass by re-engineering internal well hydraulics, and then combining this change with smaller well head treatment systems, lowers capital improvement costs as well as treatment costs and O&M going forward year-over-year.  “In-Situ Hydraulically Assisted Treatment” (“IHAT”) through “Synergistic Well Modification” results in less contaminant mass to be treated, fewer bed loads of hazardous waste that are generated and removed, disposed of and recycled, and lower pass-through costs to rate and tax payers.

Use of test pumps (as opposed to the well’s primary pump) is avoided in order to reduce testing costs as well as preserve data integrity by testing under operating conditions. Use of the primary pump yields a definitive result as opposed to a less certain simulated result with the test pump, and avoids the costly procedure of removing the primary pump.

Other IP applications include some significant state of the art advancements to existing and patented US Geological Survey technologies that are exclusively licensed to BESST. These new advancements in flow and water chemistry profiling technologies are significant in terms of reduced time to complete down-hole surveys, tighter controls on down-hole data acquisition and state of the art improvements in data resolution and processing!  In some cases, the time reduction can be as much as 30%.

Some of our more basic but forward thinking technologies include development of multi level slant wells for both shallow and deep groundwater monitoring applications as well as integration of down-hole real-time sensing technologies.

More advanced areas include development of flow-velocity and chemical sensors using fiber optics and laser induced fluorescence (LIF) to track flow under ambient conditions.

Another exciting area includes development of in-situ VOC sample and capture technologies whereby VOC contaminants are sampled and captured at the pore level, containerized down-hole at actual pressure and temperature conditions and then transported back to ground surface without container transfer prior to and during transit to the laboratory.

BESST also continues to advance its tracer based technologies towards profiling of long screened wells in the municipal, agricultural, industrial and environmental sectors.

Big Data! Selective Extraction Database

In 2005, BESST began profiling municipal supply, agricultural and industrial wells throughout California, Texas, Arizona, Nevada as well as other states.  Over the past 11 years, we have accumulated the largest dissolved aqueous phase geochemical data base for aquifers throughout California.  This trend continues to grow towards the same horizon in other states as well.  We are in the process of developing a subscriber end-user dash board that will assist banks, insurance companies, commercial and residential real estate developers, agricultural concerns and municipalities to make critical investment, underwriting and growth decisions based on in depth knowledge of quantity and quality of groundwater resources.
