METHOD AND APPARATUS FOR ANALYZING GAS FROM DRILLING FLUIDS
First Claim
1. A system comprising:
- a gas extractor including;
a gas extraction chamber within a gas extractor housing; and
a gas outlet in fluid communication with the gas extraction chamber so as to allow gas separated from a drilling fluid within the gas extraction chamber to exit the gas extraction chamber; and
a gas analyzer including an optical analyzer and an optical source that are situated outside of the gas extractor, wherein a gas analysis zone in fluid communication with the gas extraction chamber is optically connected via at least one fiber optic cable to the optical source and the optical analyzer, wherein the gas extractor includes the gas analysis zone.

Abstract
A system for analyzing gas extracted from drilling fluid is provided. In one embodiment, the system includes a gas extractor having a gas extraction chamber within a gas extractor housing and a gas outlet for gas separating from the drilling fluid within the gas extraction chamber. Further, the system includes a gas analyzer, which has an optical analyzer and an optical source that are situated outside of the gas extractor. A gas analysis zone is in fluid communication with the gas extraction chamber and is optically connected via at least one fiber optic cable to the optical source and the optical analyzer. Additional methods, systems, and devices are also disclosed.
