Available from AMS Instrumentation and Calibration , McCrometer’s precision V-Cone steam-injection flow meters support enhanced oil recovery (EOR) technologies that produce heavy oil from demanding environments, such as shallow oil sand deposits and other challenging formations.
Featuring unique differential pressure (dP) technology, McCrometer’s self-conditioning V-Cone flow meters provide superior flow measurement accuracy and repeatability for upstream oil/gas engineers over a broad flow range regardless of fluid dynamics.
Accuracy is ±0.5% with repeatability of ±0.1% over a wide turndown. The V-Cone offers a long lifespan and low cost of ownership thanks to zero maintenance and recalibration requirements.
Steam injection has become an increasingly popular thermal process for third stage oil production. This EOR method is used to restore pressure, reduce viscosity, and improve flow to prolong the life of the oilfield. Steam flooding is used for shallow oil reservoirs with heavy viscous oil and can reach recovery rates of 50-80%.
In steam flow, the pressure difference exhibited between the V-Cone flow meter’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.
The V-Cone reduces permanent pressure loss by 75% compared to a traditional orifice plate. In addition, steam flooding requires multiple meters to monitor the process that must operate over the life of the field with low maintenance requirements to make the operation cost-effective.
Key features of McCrometer V-Cone steam-injection flow meters:
- 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, eliminating the need for costly periodic inspection and replacement of plates
- Inherently more accurate design since 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 reduces the upstream/downstream straight pipe run required by orifice plates and venturi tubes by up to 70% increasing material and installation labour cost savings
