We need to measure the Electric Power consumption (kW power intake) of electric motors driving Pump Jacks in oil wells.
I am pretty sure this requires the use of a special type of meter due to the cyclic nature of the pump operation (along its cycle it goes from high to low % Load values)...

Would certainly appreciate comments/opinions on this.
Here is the case:
A premium (higher price) is paid at receiving terminals for Crude from upgrading processes (e.g. delayed coking) depending on its temperature when it reaches destination. The particular case I know of refers to terminals...
I am not EE and need to understand this issue a bit better (from the process energy use optimization perspective).
When an AC Induction motor operates under partial load conditions, the Power Factor and the motor Efficiency go down. There are a number of ways to resolve this issue but any of...
Centrifugal pump manufacturers specify a Low Flow Rate Limit value for a given pump . In addition, there are a number of "rules of thumb" etc. to estimate the value of that low flow limit (e.g. don't go below 30 % of nominal flow etc.).
The manufacturer's figure as well as most of the estimates...
When a centrifugal pump is driven by a VSD (AFD), there is a different Head (H) vs. Flow Rate (Q) characteristic curve for each value of the speed (rpm).
Using Affinity Laws, it is possible to calculate points of the same efficiency over the different curves (e.g. from the values of H and Q of...
Does anybody know if there are recommended values (list, table etc) for maximum velocities of crude oil in pipelines depending on crude API and type (e.g. waxy, asphaltenic etc) ??
Thanks and regards,

For a preliminary cost assesment/comparison of surface facilities, I need to estimate the capital cost for a SEPARATION STATION (e.g. total equipment cost without installation as this could vary depending on location, accessibility, transport costs etc).
The estimate does not include the tank...
