Bottom Hole Nodal Oil Guo-Ghalambor Method

This spreadsheet calculates flowing bottom hole nodal pressure based on tubing head pressure and tubing flow performance using Guo-Ghalambor Method.

Bottom hole nodal oil spreadsheet is tools to calculate bottom hole pressure and based on tubing head pressure and liquid fluid rate.

On this spreadsheet user have to fill some parameter such as :

Input Data:

• Reservoir pressure: 3000 psia
• Total measured depth: 7.000 ft
• Average inclination angle: 20 deg
• Tubing I.D.: 1,995 in.
• Gas production rate: 1.000.000 scfd
• Gas specific gravity: 0,7 air=1
• Oil specific gravity: 0,85 H2O=1
• Water cut: 30 %
• Water specific gravity: 1,05 H2O=1
• Solid production rate: 1 ft3/d
• Solid specific gravity: 2,65 H2O=1
• Tubing head temperature: 100 oF
• Bottom hole temperature: 160 oF
• Tubing head pressure: 300 psia
• Absolute open flow (AOF): 2000 bbl/d
