Right¡¡. Now I've adjusted two controls in the VSD: PID control using downhole and surface measurements to calculate the fluid level, the pump speed is changed to maintain that level. Also low load control, adjusted following the pump manufacture curve, if the pump load is below to the load of...
Thank four your comments
This is a hypothetical situation. As you know, the principal problem in CBM is the fluid level in the casing which is needed to protect the pump ( any pump).
The installation of the downhole sensor is expensive in most of the cases, and I'm just trying to find a way...
In Order to estimate the fluid level in CBM's wells, without using downhole sensors is possible say:
Fluid Level = (Pr -Q/j - Pcasing)* 2.35
Where J and reservoir pressure are known and they can be considered the same during definited time
Is possible to say that the Pump Intake pressure =...
