Abstract
An optical detection system for analyzing a fluid sample including a light source configured to emit a light beam to interact with the sample to form a spectrum, an optical fiber to transmit the spectrum, an array of single-photon detectors (SPDs), and wherein each SPD is configured to receive and is tunable to analyze spectral characteristics of the spectrum across a spectral range.
Claims20
An optical detection system for analyzing a fluid sample taken within a wellbore, the optical detection system comprising:
- a sample chamber locatable within the wellbore, the sample chamber configured to contain the fluid sample;
- a light source configured to emit a light beam to interact with the fluid sample to form a spectrum;
- an optical fiber to transmit the spectrum uphole;
- an array of single-photon detectors (SPDs) locatable atop a surface;
- and
- wherein each SPD is configured to receive the spectrum via the optical fiber and is tunable to analyze spectral characteristics of the spectrum across a spectral range.
A method for analyzing a fluid sample taken within a wellbore, comprising:
