How To Calculate Drilling Mud “ Lag Time “ & Wellbore Wall " Wash Out “

It is better to be: Dr. Helmi students, Drilling Fluids Engineering course: In this video,the 2 important equations of Lag time - in pump strokes - calculations are shown. One equation quantifies Lag In and the other Lag Up. Wash Out in Barrels/Mud is also calculated/explained. Lag Time in - Pump Strokes - is of daily use by the Drilling Rig Team, Wellsite Geologist, and Mud Logging Team. It accurately determines the "Wash Out" in Barrels. Part I of my Drilling Fluids Engineering Course. Enjoy the Video.

The Title this time is correct but the Gentleman who helped me to post the video here copy/pasted my message to him into the description as it is!!!!! This is the second time to upload the video!!

Very good explanation Dr. Ahemed..

Eff = initiative 😁

Thank you for taking time to put these calculations into a video, but do you need to factor in your pump efficiency? liner and swab size are factors in these calculation as well? triplex pump example|| Output bbl/stk =
0.000243 x (Liner ID inches)2 x Stroke inches x Eff % Im just a curious youtube viewer who works on rigs

Hallo sir, I have pump for acidizing, how search calculation plunger pump???

Thank you

[@georgerichardson964]

the equation should be ID" X OD" / 1029,4. the ,4 makes a big difference.

Thanks for this correction.
