Finding lost/abandoned water wells

[Carl]

Most transmitters operate in the VLF range with extremely low power levels, almost non-existant. This makes them FCC-legal.

But regardless of what frequencies or power levels you r device uses, the USPTO will not reject a patent claim because the use of that claim uses illegal or, more accurately, unlicensed bands. I could patent a novel new radio architecture even if it's use violated FCC regs. I just couldn't use it.

Carl : Begins to make one wonder why they, manufactures/vendors, don't at least copywrite the name and drawings of their units? After all copywrite does not laspe quickly like a pattent does. Unless I am wrong patents become open after 7 years, while copyrights are almost forever, also much cheaper, last I looked $10..00. Regards Marc And thanks for answering in the contsct it was meant.

I'm seeking any info on using magnetometers to find lost or abandoned or buried


steel cased water wells or drive point wells.


Thank you

If you are looking for a cheap and easy approach I suggest that you try self


potential first. All you need is a good quality meter that will read


millivolts. Of course any magnetometer will do the job if you can hire or


borrow one. Try any university with a geophysics department. They may have


an old Jalander or something like that lying around.

Thanks for the response. Finding lost wells gets a lot of attention in


Minnesota. Any time you sell property with a well, you have to fill out a Well


Disclosure Certificate and disclose if the well(s) are in-use, not in use or


sealed by a licensed well contractor. Not in use wells are required to be


sealed. Sellers who falsely disclose have a 6 year period where the buyer can


sue the seller for cost of sealing and legal fees. If no well is disclosed


then the county recorder rubber stamps that on your deed. We estimate there


are about 1½ million wells in Minnesota.


When property owners can't figure out where there wells are they are supposed


to get the Well Contractors to help find them. But Well Contractors would


rather drill new wells than find old ones so sometimes our well inspectors find


the wells. Someday we may need to license "Well Finders", but for now to find


lost wells our inspectors use mostly utility locators and backhoes.


Last year another agency loaned us a "junk" magnetometer. A MP-3 Proton


Magnetometer with VLF-3 VLF Electromagnetic Receiver and IGS-2 Integrated


Geophysical System Control Console. At first the magnetometer was


overwhelming. But other agency showed us what buttoms to push and we


discovered a new world of well locating. The magnetometer is way more


sensitive than the utility locators we have and it gets used all of the time.


It finds and pinpoints buried wells, wells in demolition areas and at other


difficult sites. I think it could pinpoint a deep buried well under a buried


car body. We will probably have to give back the magnetometer someday. So


what other tools /brands should we consider buying?


We also have the problem of getting magnetometers to the well contractors.


What types of magnetometers would be durable, convenient, reasonably affordable


and definitlely more accurate than a utility locator.

This is fascinating stuff, but how does the mag detect the well? I have


only been thinking of ferrous type targets..........

Steel casing wells (drilled) give a good strong magnetic signal and with the


magnetometer we borrowed the anomally is a distinct bullseye and the bullseye


pattern shows right thru large amounts of overlying metal junk. Driven wells


like well points are smaller in diameter so their anomally isn't as distinct.


Dug wells often have metal anchoring for a windmill or other ferrous stuff.
