I am Certified Automation Professional (CAP) having 25 Yr of experience in Oil&Gas and petrochemical industry, in the field of design, selection, commissioning & maintenance of various type of analytical and gas chromatography. I have designed, commissioned and maintained many innovative solutions for sample conditioning system for SWAT, Furnace Flue gas & 3-ph gas test separators.

Improving Quality & Accuracy of Gas Well Testing by in-situ Water Analyzer.

Innovation in Analytical Techniques

Abstract: Using conventional 3-Ph Fixed Gas Separator for gas well testing is costly, time-consuming, also requires lots of operator intervention. The new emerging trend is to use the Multiphase flow meter (MPFM), which analyze the well fluid without physical separation and calculate gas and condensate produced by well. Since the well fluid also contains water which affects the flow calculated by MPFM, for accurate calculation, it is highly required to know the water content in the well fluid. Water content is a key measurement parameter for any well and it is also necessary for fiscal allocation, reservoir management, and well performance.

The traditional Nr-IR based water analyzer can monitor water content in oil but when it is required to measure the water content in condensate they fail as spectrum used to measure water has the same absorption as condensate. So for accurate monitoring of water in the condensate, we have used water analyzer with added IR-spectrum, technically called the 5th spectrum.

This paper will discuss the challenges faced and how we could overcome while selecting, designing, commissioning and maintaining the water analyzer. It also discusses about how the parameters are optimized to fine tune it for different type of gas well containing different fluid where the GCR (Gas-To-Condensate Ratio) ranges from 80 to 99.9%, water content varies from 0 to 15% and also brine salinity varies lot from reservoir to reservoir and from one well to another well for the same reservoir.
