Reagent Description

RMD-5 is designed for bottom-hole treatment in injection and production wells in clastic and carbonate reservoirs, when the reservoirs are opened using perforation, reperforation of reservoirs, when the well is shifted into upper and lower formation ranges and horizons, and also when the wells are washed.

The reagent is used in oil production processes by adding to various process fluids at the following facilities:
• wells with reduced filtration characteristics in the bottom-hole formation zone;
• wells with a decreased flow rate during operation at constant or increasing reservoir pressure;
• wells with filters contaminated during repair processes.

Features

RMD-5 has an improved set of physical and chemical properties that meets modern requirements. Surface activity of reagent solutions in fresh water is more than double that of alternative reagents, more than 10 times higher in saline water (Figure 1)

It reduces the interfacial tension at the oil-water interface to 0.11 mN/m, regardless of salinity.

RMD-5 reagent is compatible with all types of reservoir water, it can prevent precipitation in reservoir pores.

It reduces capillary resistance to the flow of oil-water mixtures.

It has a synergistic effect that reduces the intensive adsorption of the reagent and increases its surface activity.

It has washing properties that enable the removal from the bottom-hole formation zone of clay particles and other impurities trapped in the formation during drilling, wire-line operations and major workover (Figure 2).

It maintains and restores the reservoir properties of the productive formation.

It washes producing strings and downhole equipment from asphalt, resin, and paraffin deposits (ARPD) and prevents ARPD precipitation.
