Custom Resistor Dividers from Exxelia Ohmcraft Help Enable Innovative Downhole X-ray Inspections
ROCHESTER, N.Y., September 22, 2020 — In order to safely and successfully abandon and cap off oil wells, downhole X-ray technology is used to check the wells for any structural damage or radioactive materials. Exxelia Ohmcraft—a leader in thick-film, high-voltage, high-precision resistor design and ...
...and manufacturing—was recently tapped to develop a custom, high-voltage resistor divider for this application
For more than 15 years, Exxelia Ohmcraft has provided custom resistors for petrotechnical analysis equipment used in downhole drilling. That’s why manufacturers of the downhole X-ray inspection platform turned to Ohmcraft to help develop a custom solution for use in this new and innovative diagnostic tool, which has already generated significant demand in the market.
While cameras are able to capture images of a well’s exterior, downhole drilling X-ray platforms enable oil companies to clearly examine the inside of the well despite harsh conditions, including exposure to high temperatures, high pressures, and fluids. The X-ray inspection helps to ensure the well’s integrity and mitigate any risks.
“The process of taking X-rays deep down inside of a well involves very powerful and specialized equipment, for which the design required reliable high-voltage resistor dividers in a small form factor—a combination that manufacturers struggled to find,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Given our experience in downhole drilling applications and the development of custom resistor solutions, we were able to work closely with the engineers to meets their needs and help them bring this technology to life for their customers.”
Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

Nouveau résonateur diélectrique, E7000
Operating frequencies in wireless communications have shifted towards high frequency band and thus frequencies higher than 1 Ghz are now commonly utilized. In addition, the microwave frequency spectrum becoming severely crowded and sub-divided into many different frequency bands, designers are systematically looking for resonators giving them a narrow bandwidth with smaller size. Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia Temex, daughter company of Exxelia Group, has developed with support of ESA and CNES, a new high-end dielectric material, E7000 series, designed for high-end filters where high Q factor is requested. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q factor and the possibility to get all the temperature coefficients upon request. E7000 provides high-performance requested for space use in the frequency range 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Typical applications: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
