Alkalinity (Pf, Mf & Pm) – Water Based Mud Testing
Test to determine nature and source of alkalinity in the mud and give an indication of mud condition. Correct interpretation of the results will highlight Carbonate / Bicarbonate contamination of mud which can lead to increased gel strength and YP.
One sample of filtrate is used for determination of Pf and Mf; the Mf is measured after the Pf has been determined.
A pH meter can also be used for this test instead of indicators, in which case, the Pf / Pm end point should be determined at . . .
