Drilling Knowledge: pH in the drilling mud
Drilling Knowledge: pH in the drilling mud

pH in the drilling mud. PH is a value representing the concentration of hydrogen ions in the liquid. We use it to indicate the acidity or alkalinity of the drilling mud in particular water-based mud .General talk pH. The pH is presented in a numerical value (0-14) which means an inverse measure of the concentration of hydrogen in the liquid.
