What is Bentonite? |
It is an Absorbent Aluminium phyllosilicate, basically a impure clay , it is usually formed by weathering of volcanic ash, and mostly in the presence of water.
Sodium Bentonite is one of the major families it’s properties cause it to expand when wet and possible absorbing several times it’s own mass in water. Because of it’s excellent colloidal properties, makes this possible to be used as a drilling fluid in the drilling for oil, gas, water, geo-technical and environmental areas |
Where does Bentonite come from? |
It’s first discovery was in the USA around the 1890’s but it is now found in germany, australai, Greece, turkey and China but one of the puriest sources found is in Wyoming USA |
What is the PH of neutral water? |
= 7
Less than 7 indicates acidic
Greater than 7 indicates Alkaline |
What is the Density of fresh water? |
Density of fresh water is. SG= 1 |

|
What are the major critera when drilling a bore hole?
Drilling is a intrusive action. |
- Keep the hole as stable as possible.
- keep invasion and damage to a minimum
- keep stable
- remove cutting’s efficiently
- Cutting action to be correct
- have good solids control
|
What are the functions of a drilling fluid? |
- Flush cuttings from the hole being drilled.
- Lubricate the drill string.
- To keep the drilling bit assembly cool.
- control Formation fluid pressures as needed.
- prevent loss of fluids into permeable zones.
|
What costs of drilling is the drilling fluid? |
The average cost is approximately 8% of the drilling cost, but has a great effect on all the other costs. |
What are the Main Reasons for choose of drilling fluids and Company? |
