What is Solids Control Equipment its importance
in the Drilling Process

• During the drilling process, solids need to be
  removed from the fluids in order for it to be
  reused.
• There are two options available in order to
  keep control of the percentage of Solids
• 1- Dilution
• 2- Solids Control Equipment

Concepts

• Partical Size

Category Size Example
Colloidal lt 2 ? Bentonite, Clays and very fine solids
Silt 2-74 ? Barite, Silt and fine solids
Sand 74-2.000 ? Sand and solids
Gravel gt 2.000 ? Solids, Gravel and Coal

SHAKERS

• 1st line of defense in the process of extracting
  solids from the fluids.
• The Shaker is the only piece of equipment that
  removes the solids based on particle size.

Linear Movement
Even Eliptical Movement

Cover Angles
High inclination covers with angles (gt 3)
reduce solids transportation and separates soft
solids through the screens.

Degassers

• Used to remove bubbles of gas suspended in the
  mud.

Mud Cleaner

• Hydroclones mounted over a shaker.
• Solids are passed through the Hydroclones and
  separated particles pass through the shaker on
  screens.
• Fine solids pass through the screen .
• Bigger Particles remain on the screen and are
  removed manually.

Centrifuges

• Important points to operate centrifuges
• The process of the Centrifuge
• Remove solids of high and low gravity
• Centrifuge Bowl Adjustment Deep for an optimum
  cut, and less depth for more volume.
• High RPMS for more G force
• Low RPMS For solids with more specific gravity.
• The operator has to look for the optimum
  adjustment depending on the process.
• The Function of the Centrifuge
• To remove the solids which are the most dangerous
  to the mud which are 5-10 microns in size
• produce a dry cutting.
• Barite recovery
• De - watering Solids and fluids separation with
  polymer enhancement.
