What Are The Names And Types Of Drilling Fluids Used In Oil And Gas Company
During Drilling?
Drilling fluid (in the vernacular, Mud) is three base types, water, oil, and synthetic.
My Experience As a Driller
The vast majority of my experience through most of California has been water
base mud. As mentioned, we use a variety of additives but the biggest component
is Bentonite. It helps to lubricate the hole, build the wall cake, and helps build
viscosity to help carry cuttings to the surface. There are numerous other potential
additives bases on water pH, formation composition, and even wellbore design.
Oil base is a very limited application. I DESPISE oil base. The only times I've ran oil
base has been in high deviation well bores. The oil helps tools to make the bends
and direction changes easier to reduce potentials for key hole and differential
sticking. When it comes to being 6500 ft Measured depth (not TVD), and the well
path makes extremely tight turns, dives, and even uphill sections, getting stuck
SUCKS!
Synthetic mud’s… I've only used a few times in extremely high deviation well
bores with directional work. I'm talking, like laying the string horizontally across
the bottom of the pay zone! Synthetic is extremely expensive and turns the
drilling floor into a dangerous slip and slide! It is extremely viscous while also
being absurdly slick. Think about a massive blob of snot and you're not too far off!
It makes racking pipe back on a trip an adventure!
Now, as for any further specifics, the OP is more than welcome to ask, but this is a
pretty good list of what can be encountered on the drill rig.
