Fluids/Chemicals
Reference SSG9975P19/05
Date 12/8/2018
Location Asia
Scope The company announces its need for supply of 1000 bags of resineated Lignite (25 Kg/ Bag). High Temperature High Pressure Fluid Loss And Rheology Control Agent.

The instruments to be supplied are as follows: -
- Item 001 Qty=1000 of High Temperature High Pressure Fluid Loss and Rheology Control Agent.

1. Physical State :
The material, as received, should be black or brown coloured free flowing powder, free from lumps, dirt and foreign matter.
2. Moisture Content, measured at 105 +/- 2 DegC., % by mass Maximum. : 15.00
3. Solubillity in Distilled water at 26 +/- 2 DegC, % by mass minimum : 70.00
4. Apparent Viscosity of 2 % solution in distilled water at 26 +/- 2 DegC, cp, maximum. : 3.00
5. Caking Tendency : Should not display any caking tendency when heated to 50 DegC
6. Chemical Assy % by mass :
(i) Element Iron maximum : 1.80
(ii) Elemental Chromium maximum : 0.10
7. Performance Test : A In Fresh Water Mud :
(i) Preparation of base mud Prepare a 10% (w/v) bentonite suspension in distilled water using OI approved bentonite and stir the suspension in a multimixer for 15 minutes so that no lumps are left after the stirring period. Age the suspension for 72 hrs. at 90 +/-2 DegC. After the lapes of the aging period. cool the suspension and adjust the apparent viscosity to 52.5 +/- 2.5 cp by dilution with distilled water, if necessary Divide the mud into two parts.
(ii) Untreated mud Age first part of base mud at 160 +/-2DegC in rolling condition for 24 hrs. cool the mud and stir in a multimixer for15 minutes. Determine apparent viscosity at 26 +/- 2 DegC and HPHT fluid loss at 160 DegC and 500 PSI differential pressure.
(a) Apparent viscosity, cp : To determine
(b) HPHT fluid loss, ml : To determine
(iii) Treated mud. Treat second part of base mud with 2.0 % (w/v) of the resinated lignite sample and stir the mud for 30 minutes in a multimixer. Adjust the PH of the mud to 9.5 - 10.0 by addition with 5N NaOH solution, if necessary. Age the treated mud at 160 +/- 2 DegC for 24 hrs. in rolling condition. cool and stir for 15 minutes in multimixer. Determine apparent viscosity at 26 +/- 2 DegC and HPHT fluid loss at 160 DegC and 500 PSI differential pressure which should be as follows.
(i) Apparent viscosity, cp, maximum : 40 % of 7A (ii,a).
(ii) HPHT fluid loss, ml maximum : 50 % of 7A (ii,b)
B In Saline Water Mud :
(i) Preparation of base mud Prepare a 10% (w/v) bentonite suspension in distilled water using OIL pproved bentonite and stir the suspension in a multimixer for 15 minutes so that no lumps are left after the stirring period. Age the suspension for 72 hrs. at 90 +/-2 DegC. After the lapes of the aging period. cool and stir the suspension for 15 minutes in multimixer and determine apparent viscosity which should be 85 +/- 5 cp To this mud add 4% Nacl (w/v) (LR grade ) and stir for 30 minutes in a multimixer. Age the mud 24 hrs. at 26 +/- 2 DegC .After aging,stir the mud again for 15 minutes and determine apparent viscosity at 26 +/- 2 DegC which should be 32.5 +/- 2.5 cp. Divide the mud into two parts. by dilution with distilled water, if necessary Divide the mud into two parts.
(ii) Untreated mud. Age the first part of saline mud for 24 hrs. at 160 +/-2DegC in rolling condition cool the mud stir for 15 minutes and measure apparent viscosity 26 +/- 2 DegC and HPHT fluid loss at 160 DegC and 500 PSI differential pressure.for 24 hrs. cool the mud and stir in a multimixer for15 minutes. Determine apparent viscosity at 26 +/- 2 DegC and HPHT fluid loss at 160 DegC and 500 PSI differential pressure .
(a) Apparent viscosity, cp : To determine
(b) HPHT fluid loss, ml : To determine
(iii) Treated mud. Treat the second part of the saline mud with 2. % resinated lignite sample and stir the mud for 30 minutes in multimixer. Age the treated mud for 24 hrs at 160 +/- 2 DegC in rolling condition. cool the mud and stir in multimixer foe 15 minutes. Determine apparent viscosity at 26 +/- 2 DegC and HPHT fluid loss at 160 DegC and 500 PSI differential pressure which should be as und
(i) Apparent viscosity, cp, max. : should not be more than that of 7B (ii,a).
(ii) HPHT fluid loss, ml max. : 50 % of mud of 7B (ii,b).
8. Packing :The material should be packed in good quality moisture proof multiply paper bag strong enough to withstand rigours of transit and storage. Capacity 25 kg net per bag.
9. Marking : Each bag should have clear legible marking as given below .
(i) Name of the product.
(ii) Name of the supplier/manufacturer.
(iii) Date/Month/Year of Manufacturer.
(iv) Supply order No. against which the present supply is made.
NB:The apparent viscosity shall be measured by a Fann VG meter and the HPHT fluid loss shall be measured in standard HPHT fluid loss apparatus using nitrogen gas as the pressure source.
