Low tox drilling mud is water based.
Yes, it is. Drilling fluids, the circulating fluid for drilling operations, is a mixture of the fluid, the solid and chemical agents. It is usually known as the "mud" or the "blood of drilling" deriving from its distinctive significance.

Yes, minorly, it is drilling mud.

Mud conditioning is a term used in well drilling operations. It is simply, the treatment and control of drilling mud to ensure proper gel strength, viscosity, density etc.
how we envalution PHPA in mud drilling?
Drilling mud is like blood of the drilling well without their ciculation drillling isn't possible, then u can imagin how much important its?
Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulfate (barite), calcium carbonate (chalk) or hematite.
whenever you are drilling through the pay zone, gas contained zones or shallow gas zones there is the risk of having gas in the mud. As you are circulating the mud throthe annulus if the hydrostatic pressure of the column of mud in the annulus is less than the formation pressure then the gas will rise. Note that the gas can be contained in the mud which is called gas cut mud.
