Hi guys...

I am looking for some spreadsheets (excel) or software to calculate the ECD in drilling operations (circulatin, drilling, coring, etc). If you have the M-I , BJ fluids or QMAX spreadsheets i will appreciate it.

Anyway, if you have your own calculations (taking into account the drilling string RPM, type of fluid, relationship between hole OD and string OD, mud properties...) please upload it or send it to me

regards
