Scenario:
A drilling engineer is working on a new oil well in a region with high formation pressure. They need to prepare a drilling fluid with a density of 11.5 pounds per gallon (ppg). They have a base drilling mud with a density of 9.8 ppg.
Task:
Calculate the amount of KCl (in pounds) needed to be added to 1000 gallons of the base mud to achieve the desired density.
Use the following formula:
Mass of KCl = (Desired Density - Base Mud Density) * Volume * KCl Density
Instructions:
Mass of KCl = (11.5 ppg - 9.8 ppg) * 1000 gallons * 1.98 ppg Mass of KCl = 1.7 ppg * 1000 gallons * 1.98 ppg Mass of KCl = 3366 pounds
Therefore, 3366 pounds of KCl are needed to be added to 1000 gallons of the base mud to achieve the desired density of 11.5 ppg.
