Avo Photonics, Weatherford develop downhole multi-channel photometer

Posted on 12 February 2014

Avo-produced multi-channel photometer inside the Weatherford sensor.

The design of the downhole multi-channel photometer sensor allows the device to perform high-quality photometric analysis.

Avo Photonics, an opto-electronic design and production specialist, in collaboration with Weatherford, has designed and validated the performance of a downhole multi-channel photometer. The sensor has completed field trials and is being manufactured for commercial deployment.

The reservoir fluid analyzer sensor conforms to a 4 ½-in. diameter space performing downhole fluid analysis up to 5 km below the earth’s surface. The sensor design allows the device to perform high-quality photometric analysis while withstanding operating temperatures from 20-77°C with total differential pressures up to 30,000 psi.

“Avo’s optical and opto-mechanical design and manufacturing expertise for harsh-environment operations and their rapid understanding of the downhole challenges were critical to create a sensor assembly that would work within our existing wireline equipment,” said Dr Jess V. Ford, senior staff scientist of Weatherford.

“Designing and manufacturing an optical fluid analyzer for downhole is challenging, and Weatherford’s extended long wavelength requirements compounded the difficulties of high-temperature performance,” said Dr Thomas Haslett, chief technology officer of Avo Photonics. “We created an original design from our unique perspective.”
