How does barite/baryte work in oil/gas drilling industry?
Drilling grade Barite (BsSO4) 4.1 ~ 4.2 Specific Gravity is used to
increase the weight of fluids. Barite or baryte is a mineral
consisting of Barium Sulfate.
Some 77% worldwide is used as a weighting agent for drilling fluids
in oil and gas exploration to suppress high formation pressures and
prevent blowouts. As a well is drilled, the bit passes through
various formations, each with different characteristics. The deeper
the hole, the more barite is needed as a percentage of the total
mud mix. An additional benefit of barite is that it is non-magnetic
and thus does not interfere with magnetic measurements taken in the
borehole, either during logging-while-drilling or in separate drill
- To clean cuttings from the well bottom.
- Flush those cuttings to the surface.
- Cool and lubricate the drill bit.
- Deposit a “filter cake’ layer on the well bore wall to prevent
loss of the circulating fluid.
- Prevent formation fluids entering the borehole and mixing with
- Support the walls of the well bore without damaging the
- Control pressures under the surface.

Communication with customers:
A: Hello Tokusyo, are you the barite/baryte mine owner?
B: Yes dear, we are the barite mine owner, and our mines locate in
A: Can you provide 10,000tons of barite lump monthly.
B: Yes off cause, we can provide more than that number, it’s about
A: What is the packing condition of your barite/baryte lumps.
B: If your quantity is more than 3,000 tons, we can ship them
through bulk loading, and if your quantity is less than 3,000 tons,
we suggest the container lose loading.
A: What are your payment terms?
B: T/T and LC is workable for us, so it is up to you.
A: How do you control your quality to make sure your product could
meet our requirements?
B: We have various kinds of methods to control our quality. First
of all, we have a full set of test machines in our factory such as
specific gravity testing machines, particle size testing machine,
and moisture testing and whiteness testing machine. And besides we
work with the third party inspection institution SGS, we can
arrange the inspection according to customers’ requirements before
the product shipped. We can be 100% sure that we can deliver the
right product to your hands.
A: that is perfect, and i can feel that you are very professional
supplier and let’s try it.
