Tendeka models ACID inflow control devices

Smart well technology modeled and validated with multi-phase simulation.

A new white paper from completion specialist Tendeka covers autonomous inflow control technology. Managing inflow and reservoir sweep is often a limiting factor on the length of a horizontal well as the benefit of greater reservoir contact is offset by increased differential drawdown and a tendency to cut across formations of different permeability. Passive inflow control devices (ICD) are often used but cannot be adjusted in the event of water or gas breakthrough.

Autonomous ICDs (AICD) offer greater control of fluid influx, mitigating breakthrough. They can lead to greater recovery and lower water cut. To manage such devices, Tendeka has developed a comprehensive multi-phase flow model of AICD performance which can be used to model inflow distribution along the wellbore. The model has been validated by extensive testing in a multi-phase flow loop and real world results from over 10,000 Tendeka AICDs in some 50 wells around the world. Tendeka recommends checking flowing bottom hole pressures with a steady state computation such as provided by Landmark’s NETool for model verification. Tendeka’s AICD evaluation workflow was originally developed by Statoil.
