METHOD OF ASSESSING CHEMICALS IN PRODUCED FLUIDS

摘要

A method of monitoring water-soluble treatment chemicals in a fluid that is immiscible with water and which may or may not contain some aqueous fluid, the method using at least one reagent that produces an optically detectable product, the detection step can take place without separation of the aqueous phase containing the treatment chemicals from the fluid immiscible with water.

主权项

1. A method of monitoring water-soluble treatment chemicals in a fluid that is immiscible with water and which may or may not contain some aqueous fluid, where said water-soluble treatment chemical is a hydrate inhibitor, the method comprising:
a. obtaining a sample of said fluid; b. adding a first reagent to the fluid sample, wherein the first reagent is an oxidising agent being reactive with the treatment chemical to produce a first product, wherein the first product is an aldehyde; c. adding a second reagent to the fluid sample, wherein the second reagent is an aldehyde reactive reagent being reactive with the first product in step (b) to produce an optically detectable second product; and d. detecting an optically detectable product;wherein the detection step takes place without separation of the aqueous phase containing the treatment chemicals from the fluid immiscible with water.
