Balanced-Activity Oil Mud
Definition - What does Balanced-Activity Oil Mud mean?
Balanced activity oil mud is a drilling mud that is specifically used to balance out the activity or the vapor pressure of brine when it reacts within the rock formations. The shale sections may not have a steady vapor pressure; however, the balanced activity oil mud instantly adjusts it to an average state. This oil mud is important while carrying out drilling operations because without it, neither the vapor pressure nor the activities inside the wellbore would be stabilized. The mud also balances out the salinity of the brine and mud in the shale sections.
Petropedia explains Balanced-Activity Oil Mud
Different kinds of drilling fluids are used during the drilling of an oil well. A balanced-activity oil mud is a special drilling mud or drilling fluid that is used for stabilization inside the wellbore. When brine fluid is injected inside an oil well, it can react with the rock formations and can disturb the natural pressure of the well. By using the balanced activity oil mud, the activity as well as pressure inside an oil well can be balanced easily. Since brine fluid has salt in it, the salinity can affect the balance inside the shale sections.
