Biopolymer as Viscosifier (H T) Supplier and Manufacturer

Biopolymer as Viscosifier (H T)


Detailed product Description

Biopolymer as Viscosifier (H T) is a high molecular weight polysaccharide produced by viscous fermentation.
Its unique functionality compared to other commercial polysaccharides is provided by the Actual structure of the xanthum gum molecule. It is widely used as a thickener and stabilizer.
Oil drilling and exploitation grade xanthum gum is specially produced mud additives for Oil drilling and exploitation. Being environmentally friendly and high efficiency mud additives, Oil drilling and exploitation grade xanthum gum has an excellent tolerance to the change of temperature acid, alkaline and salt. Meanwhile it can extremely increase the products penetrating ability and suspending performance to small solid materials, and reduce the pressure loss during drilling. 
This xanthum gum can not only fasten the well bore, but decrease the damage to oil formation. It can also greatly raise the efficiency of drilling, work over and completion. As a biotype oil Driver, Oil drilling and exploitation grade xanthum gum can improve oil extraction rate and utilization factor of natural resources. The more important point is that it can furthest and protect natural environment.

Physical Properties

(1). Physical State :

The material shall be a free flowing powder, free from visible impurities.

(2). Performance Test 

(i) Disperse 2% (w/v) Polymer Solution in Distilled Water by maintaining pH of 9.0 — 9.2 and stirring in a Hamilton Beach Mixer for 10 minutes. Divide the dispersion into two portions. Hot roll one portion of the dispersion for 18 hours at 70 ± 2 0C and the other at 140 ± 2 0C. Cool both the portions to 24 ± 2 °C °Cover a period of 1 hourand stir in the Hamilton Beach Mixer at high speed for 15 minutes. Determine Apparent Viscosity ( cP) at 24 ± 2 °C 0C for both the hot rolled dispersions using Fann VG Meter or Equivalent.

Apparent Viscosity of dispersions hot rolled at both 70 ± 2 ° C and 140 ± 2 C should not be less than 50 cP.
(ii) Keep the two portions of the cooled Polymer dispersions at 2 (i)above for 24 hours at 24 ± 2 °CC and stir in HEM at high speed for 15 minutes again determine Apparent Viscosity ( cP) at 24 ± 2 °C o C.
There should not be any decrease in values of Apparent Viscosity obtained for the portions of the dispersions at 2 (i) during the retention period.

(3). Insoluble Residue In 15% (w/w) Hydrochloric Acid, percent by mass on Dry Basis..............10.0 (Maximum).

(4). Acid Degradability Test :

Prepare a Cross-Linked Gel by treating a 8% (w/v) Biopolymer dispersion in Distilled Water with 0.3%    (w/v) AR Grade Borax and heating at 90 ± 20C for 45 minutes. Cool the gel to 24 ± 20C over a period of one    hour and digest with 20% (v/v) HC1 for 2 hours at 90 ± 2    °C. Cool the digested gel to 24 ± 2 °CC.
Apparent Viscosity of the digested gel should not be more than 5.0 cP. 
The Behavior Index (n') of the digeste gel should be in the range of 0.99 — 1.00.

(5). Performance Test with Bentonite Suspension:

(i)    Prepare a 10% (w/v) Bentonite Suspension in Distilled Water using VISION approved Bentonite by stirring with laboratory stirrer (5000 - 6000 rpm) for 30 minutes. Age the suspension for 72 hours at 90 ± 2 °C. After lapse of aging period, cool the Suspension to 24 ± 20C. Dilute it with Distilled Water and bring Apparent Viscosity to 15 ± 1 cP, using a Fann VG Meter or Equivalent Also determine the Yield Point (lbs/100 sq. ft) of the suspension at 24±20C.
Record Apparent Viscosity and Yield Point of the Bentonite suspension.
(ii) Treat the Suspension 5(i) with 1% (w/v) Biopolymer with stirring in a Hamilton Beach Mixer at high speed for 10 minutes and maintaining a pH of 9.0 — 9.2. Hot roll this Mud in a roller oven at 140 ± 2 0C for 24 hours. Cool to 24 ± 2 °O Cand stir again in the Hamilton Beach Mixer at high speed for 10 minutes. Determine the Apparent Viscosity (cP) and Yield Point (lbs/100 sq. ft ) at 24 ± 2 °O C. Also measure its Lubricity Coefficient, using a Lubricity Tester.
Apparent Viscosity of the treated suspension should not be less than 2 times the value obtained for suspension 5(i).
Yield Point of the treated suspension should not be less than 1.5 times the value obtained for suspension 5(i).
Lubricity Coefficient of the treated suspension should not be more than 0.30.
