Bentonite for drilling works are used for preparation of drilling fluids.
Bentonite powders types PBMA and PBMB have the following quality characteristics:
Specifications | Unit | Type | | | PBMA | PBA | PBB | Slurry yield, not less | m3/t | 22 | 20 | 17 | Moisture mass fraction | % | 10 | 10 | 10 | Filtration, not more | cm3 | 14 | 15 | 15 |
There is a possibility to produce special types of bentonite powders according to customers’ requirements.
The company also produces bentonite powder which meets the requirements of API 13A specification. The suspension properties of bentonite powder are listed below:
Specifications | Value | Suspension properties | API 13А specification | Actual value | Effective viscosity at 600 rpm | Minimum 30,0 | 39,0 | Yield point/plastic viscosity ratio | Maximum 3,0 | 3 | Filtrate volume | Maximum 15,0 см3 | 14,0 | Suspension sieve residue, 75 m | Maximum 4,0% | 2 | Powder moisture | Maximum 10,0% | 10,0 | Bentonite powders composition can be adopted due to customer’s requirements and allow reducing binding agent qty and improve the quality of drilling fluid.
