Polytamp-2 grade A is an orthosilicic acid polyesters (varying polymerization degrees) mixture with special additives. The grouting material is capable to tamp, under various conditions in accordance with the technical specifications for each individual well, without the addition of other components, including water, while it is capable to form a homogeneous (by liquid) system with water.
Polytamp-2 grade A is designed for water inflow elimination and gas and oil recovery increasing during squeeze job in gas and oil wells with a temperature of formations +10°C - +300°C.
Based on the technical specifications, the material is produced with deliberately agreed characteristics (individually for each well).
Polytamp-2 grade A limits the fluid inflow only from the water-saturated part of the seam, and preserves the permeability of oil-saturated areas.
Insulation work during the repair of wells:
Before use, the material is diluted with water (1-12 parts by weight of water or more per 1 part by weight of material).
The material is not corrosive, its application does not require the formation pre-treatment, it is applied using standard equipment (including coiled tubing units).
The work is carried out with and without lifting the downhole equipment in wells with any method of operation.
Polytamp is recommended to be stored in tightly closed original packaging at a temperature between -60°C and + 40°C, in a cool, dry, well-ventilated place, away from areas that pose a fire hazard. Protect from direct sunlight and moisture.
The guaranteed shelf life in original container is 12 months. The actual period of application is up to 3 years or more, which is associated with the high stability of the Polytamp.
Storage over the date specified on the label does not necessarily mean the product is unusable. In case, if store more please check the properties of product before use.
Steel barrels with a capacity of 100 dm3, 110 dm3, 200 dm3, 273 dm3.
Grouting material Polytamp-2 grade A is a flammable, explosive liquid. Observe the fire safety technique when processing.
