How to Analyze and determine Fluid Density and type from RFT Data in MS Excel

Analyzing Fluid Density and Type from RFT Data in Excel
This video dives into analyzing RFT (Repeat Formation Tester) data using Microsoft Excel to determine fluid density and type.
The Process:
1. Import RFT Data: Learn how to properly import RFT data into Excel, avoiding potential errors from copy-pasting.
2. Data Visualization: Create a pressure vs measured depth graph to reveal trends in the data.
3. Data Grouping and Analysis: Separate the data into individual trends and calculate the fluid gradient for each using the trendline slope.
4. Fluid Density Calculation: Explore how to convert the fluid gradient into fluid density using Excel's CONVERT function and appropriate conversion factors.
5. Fluid Type Differentiation: Understand how fluid density can help identify fluid types, with the caveat that density alone might not be sufficient.
Key Points:
• Density values are for demonstration only; actual fluids have overlapping density ranges.
• Temperature, pressure, and other factors can influence fluid density. Consider additional RFT data for more robust identification.
• The obtained densities represent downhole conditions. Use formation volume factors to convert them to surface conditions if needed.
• RFT data can also reveal information about fluid contacts (oil-water, gas-oil).
• Specialized reservoir evaluation software might offer more streamlined tools for this analysis.
