Oil and gas production
The oil and gas industry has specific requirements for the quality of the used cement. Kerwood® filler allows to achieve compliance with them, without complicating the process of construction or using harmful substances. In addition, we shouldn’t forget about other advantages of the filler.
Kerwood® as an inertizing additive in grouting mortars provides a number of advantages:
- Possibility of using single-stage cementing instead of a multistage
- Reducing the cost of repairs and restoration work
- Lowering the risk of damage to the reservoir during cementation
- Greater flow rate of the well due to the less impact on the reservoir
- Decrease in the specific gravity of the cement mortar to 1.3–1.5 g / cm3 (for a conventional lightweight gel-cement slurry of 1.52–1.54 g / cm3)
- Maintenance of the given height of the mortar rise
- Non-shrinkage in the formation of the cement stone
- Improving the connection of the layers with the well casing pipes
Backfilling with Kerwood® filler has the following qualities:
- Improved elasticity (resistance to cracks)
- Increased corrosion resistance
- Thermal resistance
- Good adhesion with metals and rocks
- Low shrinkage during hardening
- Low permeability for liquids and gases
- High strength at low density
- Ease of drilling out
We can send results of tests and laboratory studies, as well as conclusions, on individual request.
