Pwf from surface Conditions

Post by jriad »

Is there are method that would give you an accurate (or as accurate as possible) to achieve bottom hole flowing pressure from casing pressure & fluid level?

Any help or insite would be appreciated.

You can estimate the BHP from surface WHFP and flow rates by known well deviation and wellbore sketch.
Use PROSPER software for these nodal analysis

actual calculations wud involve selection odf tubing performance model...depends upon the flow survey tests to select a suitable model....

modified Hagedorn Brown model should give fairly good results..

actual equations can be found in any poduction book....or google it out

look at Kermit's or Beggs' books production technology books. you will see nodal analysis graphs.
THE TECHNOLOGY OF ARTIFICIAL LIFT METHODS by Kermit Brown
