Chemicals - Drilling / Cementing Cement Fluid Loss Additives
Reference: SSG7924P19/05 5/9/2018, Location: Asia
Category: Fluids Drilling, Completion, Workover & Stimulation
Scope of Work
The company announces its need for supply of chemicals - drilling / cementing cement fluid loss additives
low to Moderate Temperature Fluid Loss Additives.
1. Physical State : The material received should be a free flowing powder free from visible impurities.
2. Solubility : Solubility in water at 24 +/- 2 deg.C
- The material should be soluble or dispersible in fresh water.
3. Moisture content : % by mass determined at 105 +/- 2 deg.C
- 10.0 (max)
4. Performance Test :
i) Fluid loss of 44% slurry made from API Class `G' (HSR) type cement and fresh water, at 90 deg.C & 1000 psi.
ii) Fluid loss of 44% slurry made from API Class `G' (HSR) type cement and fresh water and treated with 1.0% of the sample, at 90 deg.C & 1000 psi.
- Fluid loss should be 20% (max) of the reading at 4(i)
iii) The initial and 60 minutes consistency of the slurry,
when temperature is raised from 24 deg.C to 90 deg.C
in atmospheric consistometer during fluid loss
determination.
- Should not exceed 30 BC
iv) Thickening time of 44% slurry made from API Class `G' (HSR) type cement of fresh water at 90 deg.C & 6000
psi raised in 30 minutes.
- Thickening time as per API Specification - 10.
v) Thickening time of 44% slurry made from API Class `G' (HSR) type cement and fresh water and treated with
0.5% of the sample at 90 deg.C & 6000 psi raised in
30 minutes.
- Thickening Time should not exceed 2.0 times (max)
of reading at 4(iv)
Packing : The material to be packed in 50 lbs (22.7 kg)
multiwalled moisture proof paper bags.
