Patent ID: 7844400

Claim:
A low maintenance adjustable fluid sampling system for use with a flow line of a drilling rig for a well, the system comprising: a. a gas analyzer for analyzing gas samples from a well being drilled; b. a sample conditioning and filtering device in fluid communication with the gas analyzer for removing moisture from the gas samples; and c. a gas trap in fluid communication with the sample conditioning and filtering device, for collecting the gas samples; wherein the gas trap comprises: i. a plurality of couplings connected in parallel; wherein each coupling secures to a flow line of the drilling rig for the well; ii. a plurality of hammer unions; wherein each hammer union engages one of the couplings; iii. a plurality of base manifold pipes; wherein each base manifold pipe engages one of the hammer unions; iv. a base manifold flow line for flowing gas samples from each of the couplings to a chimney pipe; v. a controllable valve in communication with the chimney pipe; vi. a connector integral with the chimney pipe for providing a pressure safety release; vii. a reducer connected to the chimney pipe opposite the base manifold flow line for modifying the diameter of the gas sample flowing from the flow line; viii. an expansion chamber component connected to the reducer having an expansion chamber diameter greater than the reducer; ix. a restrictor connected to the expansion chamber component opposite the reducer; wherein the restrictor has a diameter no more than one third the diameter of the expansion chamber component diameter; and x. a conduit connection connected to the restrictor for engaging a conduit.
