Oil-field chemistry solutions
Drilling reagents
Reagents to control loss of circulation during drilling
- Spacer (plug), formulation of fiber and polymers for generation of filter cake
- Loss of circulation:
Capsular product to be activated by boring tool for instantaneous elimination of high losses
Solutions for the applications as follows:
- Moderate losses (at any temperature)
- Critical losses (20 to 80°С)
- Critical losses (60 to 120°С)
Cementing additives:
- Gas filtration and migration control;
- Bottom-hole pack-off, production horizon shut-off;
- Protection of aquifers against contamination;
- Cement retarders for high temperatures.
Range of products for acid treatment and hydraulic fracture
Aquifer shut-off
Reagents to control water influx:
- Water influx control combined with acid treatment
- Principle of operation: gelling upon rise of acid value to normal pH=7 (under conditions of acid use)
- New concept
- Reversible (viscosity reduction) by re-addition of acid
Suitable for carbonates and sandstone
