Providing Extreme Pressure Mud Lubricant
Reference: SSG1717P17/01 7/14/2016, Location: Asia
Category: Lubricants, Oils & Greases
Scope of Work
The company invites bids for the supply of 120000 Litres of Extreme Pressure MuThe company invites bids for the supply of Qty= 120000 L, Extreme Pressure Mud Lubricant:-
- Product Description and Use:
Vegetable oil based lubricant used for imparting lubricating property to drilling fluids under normal and extreme pressure conditions.
- Specifications:
1. Physical Properties: The material, as received, should be yellow, brownish yellow, pinkish yellow coloured clear viscous liquid free from suspended materials and other impurities. The material should be vegetable oil based product, non polluting, bio-degradable, non fluorescent and should be environmentally friendly product and should not cause any pollution hazard.
The product should not be produced from petroleum oil and should not produce oil sheen in water.
2. Miscibility/Dispersibility: The material should be dispersible/miscible with water without formation of oil sheen in water.
3. Density at 26 +/- 2 degC. gm/ml: 0.92 - 0.98
4. Performance Test:
A. Lubricity Test: (i) In fresh water mud Prepare a 7.5% (w/v) bentonite suspension in distilled water using OIL approved bentonite and stir for 15 minutes in multi mixer so that no lumps are left after the stirring period. Age the suspension for 72 hrs. at 90 +/- 2 deg C. After the lapse of aging period, adjust apparent viscosity of the suspension to 15 +/- 1 cp by dilution with distilled water. To this, add 0.5% (w/v) of the sample while stirring. After completion of addition, sir further for 30 minutes in a multi- mixer. Measure lubricity co-efficient by using a lubricity tester. Lubricity co-efficient should not be more than 0.15
(ii) In saline water mud - Prepare a 10% (w/v) bentonite suspension in distilled water using OIL approved bentonite and stir for 15 min. in multi mixer so that no lumps are left after the stirring period. Age the suspension for 72 hrs at 90 +/- 2 deg C. After lapse of againg period, add 4% NaCl (w/v) (AR grade) and stir for 15 minutes in a multi mixer. Age the suspension for 24 hrs. at 26 +/- 2 deg C. Adjust the apparent viscosity to 15 +/- 1 cp by dilution with 4% NaCl solution, if necessary. To this saline mud, add 0.50% (w/v) of the sample in stirring condition and stir further for 30 minutes in a multimixer. Measure lubricity co-efficient by using a lubricity tester. Lubricity co-efficient should not be more than 0.20
