Syd, Warrior does have the tick mark feature built-in but "Services" that come wiith it by default are not customized to show the minute marks on the log. SDS ...
Awhile back I mentioned I got roped into working on what I believe is an old Precision isolation gamma sub tool. I essentially had to rebuild the dern thing...
Syd, Schlumberger used what was called a "phantom" signal technique. The signal is applied to the center tap down hole. The surface electronics picks the...
Interesting. I am sure it is not Schlumberger. Precision may have copied the idea from them. I had forgotten about the old phantom signal trick. They used...
Here are some pics of the inside of that oddball open hole Gamma Ray tool we had here in the shop: http://www.logwell.com/tech/general/precision_gamma.html If...
Anyone looking to hire an electronics technician with experience in the oilfield(Wireline, rotary steerable systems, MWD, FE, mud logging, surface)? Have...
Anybody ever come across a tool that uses a 555 as the pulse shaper and line driver? I encountered this in an open hole tool, but was wondering if the thing...
Syd, I have seen 555's misused a lot of ways. It wouldn't surprise me if they worked for that. If your not comfortable with them replacing it with what you...
Actually, I am pretty impressed with the idea. I am just not sure it has the guts to act as a real line driver in a cased hole tool. I seem to remember the...
Syd, A box full of 555's is about all you need! A casual browse of the web reveals the output will drive 100 ma into a low impedance load. Although it's...
Has anyone ever actually used a bipolar 555 to temp? I have always avoided them after I was told they wouldn't work. Sadly I never tested them myself. I...
Oops. I didn't think about not being able to drive the line with a negative pulse from a 555. It has been so long since I played with them I am not sure, but...
I dunno about temperature for these things. The tool I saw one in was clearly not intended to go above 100C. I seem to remember SIE used one in a capacitance...
The Wireline Mailing List reached 700 members yesterday, another milestone for our little group. Tell your friends about the List since we can always benefit...
One feature of the 555 is temperature stability. Pulse width stability is rated at .005 percent per degree. National Semi's devices appear to be 0C - 70C,...
A while some 15 years ago we tried to ise 555 for some other application. What the manufacturer claims about the military temperature range (125C / 250F) us...
Signetics called it the 555 time machine. I discovered FREE energy among other things when I was teaching this stuff 28 years ago at DA. My personal...
Sid, The designer says the 555 as he designed shuts down when the internal temperature gets to 140 C. So that make the environmental temperature it will stand...
Hello, I've posted an update to Uncle Raymond's Tool Box. Charles and Darrell with Cardinal Surveys in Odessa, Texas found a problem with the fluid weight...
I just downloaded URTBv32... looks pretty neat! Which leads me to comment that I've got a little programming gleam in my own eye. If you go to my website: ...

It is the old model . Battery system is poor . I wonder how it got there . Stolen ? Bankrupt of a user ? Cost much more but I would not buy. Andre LABRIET ...

Are the detonators for this available in the US? Any idea what the detonators cost (if available) and what this box originally cost? Thanks. ... From: John...
