McCrometer V-Cone steam-injection flow meters available from AMS Instrumentation and Calibration support enhanced oil recovery (EOR) technologies that produce heavy oil from demanding environments, such as shallow oil sands deposits and other challenging formations.

Steam injection is an increasingly popular thermal process for third stage oil production. Steam flooding as an EOR method is used to restore pressure, reduce viscosity and improve flow to prolong the life of the oilfield. Used for shallow oil reservoirs with heavy viscous oil, this method can reach recovery rates of 50-80%.  

In steam flow, the pressure difference exhibited between the V-Cone’s static line pressure and the low pressure created downstream of the cone is measured via two pressure sensing taps, with one tap placed slightly upstream of the cone and the other located in the downstream face of the cone itself. The pressure difference is then incorporated into a derivation of the Bernoulli equation to determine the flow rate of the steam.  

Featuring unique differential pressure (dP) technology, McCrometer’s self-conditioning V-Cone flowmeters provide superior flow measurement accuracy and repeatability over a broad flow range regardless of fluid dynamics. With virtually no maintenance or recalibration requirements, the V-Cone flow measurement equipment also operates over a long life with a low cost of ownership.  

Key features of McCrometer V-Cone steam-injection flow meters:  

  • Accuracy is ±0.5% with repeatability of ±0.1% over a wide turndown 
  • Reduces permanent pressure loss by 75% compared to a traditional orifice plate 
  • Rugged no-moving parts design with nothing to foul or break in harsh oil production environments 
  • Contoured shape of the V-Cone’s beta edge prevents it from dulling like that of an orifice plate beta edge, eliminating costly periodic inspection and replacement of plates 
  • Inherently more accurate than traditional orifice plates and venturi tubes as the flow conditioning function is built into the design 
  • Centrally located cone interacts with the steam, reshaping the velocity profile to provide a stable signal that increases measurement accuracy 
  • Built-in flow conditioning helps reduce the upstream/downstream straight pipe run required by orifice plates and venturi tubes by up to 70% 
  • Reduction in pipe requirements enables significant savings in material and installation labour costs
