Sampling Chamber with Hydrogen Sulfide-Reactive Scavenger

摘要

Systems, methods and devices for analyzing a sample of fluid extracted from a hydrocarbon-producing geological formation to detect a quantitative amount of hydrogen sulfide or disclosed. The systems methods and devices involve including a scavenger within a sample compartment to react with the hydrogen sulfide therein. The concentration of hydrogen sulfide in the sample may be derived as a function of the amount of scavenger remaining in the sample after reaction with hydrogen sulfide, an amount of byproduct of a reaction between the scavenger and the hydrogen sulfide, or an amount of hydrogen sulfide as measured following a secondary reaction that releases the hydrogen sulfide from the scavenger.

主权项

1. A downhole sample chamber for sampling fluid from a formation, the chamber comprising:
a fluid inlet; a fluid outlet; a compartment between the fluid inlet to fluid outlet; and a scavenger volume within the compartment, wherein the scavenger volume is reactive with H2S.
