IFM

DOF Engineering Workflows

IFM is a platform to build and integrate business and field management workflows. They are well over 50 workflows available.

Below are illustrated examples of available workflows in IFM:

Equipment Quality Control:

Oil Well Test Analysis

• GOR value check against Solution GOR for Undersaturated Reservoirs
• Water Cut Comparison with Water cut of latest Well Test
• Well Test Validation using Choke Performance
• Check if Downhole Gauge Pressure lies within Fancher & Brown and Duns & Ros (modified) flow correlations
• Sensitivity on VLP Matching parameters
• Current tubing correlation comparison
• Closest tubing correlation
• Sensitivity on Reservoir Pressure
• Sensitivity on Productivity Index

Gas Well Test Analysis

• Calculate the minimum WGR
• Tubing Correlation versus downhole measurement - calculates the pressure at gauge depth for the current model correlation and compares this to the pressure at gauge depth for a reference correlation

GasLift Quicklook Analysis

• QuickLook gaslift diagnostic from PROSPER

Mobility Analysis

• Calculates the Productivity Indices and regresses on relative permeability curves to give estimates of the relative permeability exponents and end points

VLP/IPR calculation (all wells types)

MultiRate Gas well analysis

• Estimates Forcheimer or ‘C and n' using multirate data

MultiRate Oil well analysis

• Estimates Productivity Index & Reservoir Pressure using multirate data

Real Time Calculator:

Well Rate Estimation

• Calculates well rates using four estimation methods based on:
• VLP/IPR calculation
• Choke performance calculation
• Inflow performance curve calculation
• VLP curve calculation

Auto Production Allocation

From the rates calculated in the Well Rate Estimation:

• Calculates reservoir cumulatives
• Updates cumulatives in the reservoir model
• Calculates reservoir pressure in the updated reservoir model
• Updates the PROSPER and GAP model reservoir pressures
