Downhole Photometer

Custom opto-electronic design and production specialist Avo Photonics, in collaboration with the Wireline R&D optical-sensor group at Weatherford International, has designed and validated the performance of a downhole multichannel photometer. The sensor has now completed several field trials and is being volume manufactured by Avo Photonics for Weatherford commercial deployment. The reservoir-fluid-analyzer sensor conforms to a 4.5-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 to 177°C and total differential pressures up to 30,000 psi.
