On a rig, mud does a lot more than land on your coveralls. The mud that circulates through a well bore is instrumental to oil and gas drilling.
In last week’s blog post, we gave you a look at a day in the life of a Derrickhand. The Derrickhand’s responsibilities include maintaining the rig’s mud systems and mud properties. This week, we want to give newcomers to the drilling business a guide to the sophisticated world of mud!
What role does mud play in the drilling process?
When a hole is being drilled, drilling fluids or “mud” is circulated through the well bore. This mud performs many functions including:
- Bringing “cuttings” to the surface (cuttings are fragments of rock dislodged by the bit)
- Cooling and lubricating the drill bit
- Controlling pressure
- Stabilizing the hole
