BACKGROUND

The disclosure generally relates to the field of drilling operations, and more particularly to bias correction for a gas extractor and drilling fluid sampling system used for drilling operations.

During the drilling of subterranean wells, a fluid is typically circulated through a fluid circulation system that includes a drilling rig and fluid treatment and storage equipment located substantially at or near the surface of the well. The fluid is pumped by a fluid pump through the interior passage of a drill string, through a drill bit and back to the surface through the annulus between the well bore and the drill string. As the well is drilled, fluids including gasses and liquids from the formation may be released and captured as the fluid is circulated. In some instances, the gasses may be wholly or partially extracted from the fluid for analysis, and the fluids may otherwise be analyzed. The gas and fluid analysis may be used to determine characteristics about the formation.
