I received this email this afternoon: I am writing to you in hopes that you could recommend someone to me. I am a recruiter in the Houston area and I am trying...
Are they only looking W-engineers who lives in north America cuz I live in Europe and I'm looking for job and if they interested in me can u send me their...

Charles, interesting, and previously argued proposal. The problem with data data storage standards and presentation formats is two-fold. First problem exists...
Syd, any chance this may have been caused by stray voltage from a near by vehicle equipped with "On-Star" or similar device? These products, found on a lot of...
Gentlemans, I am looking for some Cable Side Entry Sub 4 1/2" thread IF. Anyone knows who manufacture this kind of equipment, or someone has used CSES for...
Hello Friends Plz accept my best wishes and greeting for happy and prosperous new year 2007. I would like to discuss with you regarding the CBL combo tool....
I doubt it, but I suppose it is possible. There is allegedly a documented case of a cell phone setting off electric caps in the cab of a truck. ... From:...
That decrease in HV would certainly cause trouble. The question is what is causing it. The first thing to check is what PMT is in the tool. Judging from the...
Perry, I agree on all points. In reality, I am not optimistic that even a logtiff standard is possible. Once you or I or someone else comes up with a logtiff...
On a similar theme...does anyone on list have a recommended supplier of scintillation crystals for downhole, ruggedised and up to 200C? I've re-read the...
To All, I will try to clear the some of the speculation on what caused this incident and if necessary can ask for a formal clarification from HES on the...
On-Star & LoJack both operate at power levels & frequencies similar to cellular phones, thus posing similar RF risks. On-Star is fairly easy to disable, but...
I forgot to mention it, but you should determine how much current the Victoreen Corotron is dumping to ground. If the tool does not already have one, add a 10...
Hand-held cel phones output 300 milliwatts when they transmit. Bag-phones output 600 milliwatts. I don't have the frequencies handy - but they are microwave...
Paul: The newer Crydet crystals look very good. They have apparently invested in improved technology. I would also talk to this outfit: Gintek, Inc. Vic...
Their email address, sbenson@..., and website URL are both given at the bottom of the email I posted. ... From: dalmar To: wireline@yahoogroups.com Sent:...
These kinds of accidents are almost always caused by some kind of human error. Sometimes that error is a bad equipment design (like the horrible Applied CCL...
Never short circuited! Short circuiting a cap creates a giant loop antenna. While this is probably not an issue with resistorized caps, it is definitely a...
I know that when I was mining our procedure was nothing that can TX or RX within 1/4 mile. Including pagers. When holes were charged and the cap wires...
Chuck, Analog cell phones are around 900 MHz the digital ones are on 1,200 and 2,400 MHz. The digital phones negotiate power with the the cell. Digital phones...
We are using their crystals for our GR tools. We have no problems with them. However why do you need a 200C one. As far as my knowledge the PM tubes are up to...
Thanks Syd and Kresimir for your replies. We use the Saint-Gobain crystal and Hamamatsu PMT tubes to 175C at present - only real problem was delivery times. I...
Syd, I'm not a genius so I need some help here. When I key up my CB it doesn't blow the fuses in the car parked next to me! Speaking hypothetically (of course)...
A very simple, practical way of looking at the radio issue (on a case by case basis) is to ask whether the output power of the transmitter (watts) exceeds the...
Chuck, HES use ballistic as well as Rotary Coring devices (inherited from GOI purchase in 1989). To shotgun a SWC tool, power to cycle the control switch as...
The resistive shunt is intended to "burn up" RF energy when the shooting line is in "loop antenna" mode. This practice evolved from empirical evidence and...
Syd, You have done a great job in clearing up some of the mystery on this topic! Thanks to everyone else for the generous replies! John's information has shown...
It is really easy to make mistakes. Checklists are great, but many will not engage in the formal behavior required for them to be effective. Some time back, I...
Syd, Chuck and the Community, Give me a few days and I will resurrect a document that I assembled a few years ago (was used in many field training classes)...
