Product Description
Permeation-absorption oil recovery agents utilize the spontaneous permeation-absorption mechanism of surfactants. By reducing the interfacial tension between oil and water and altering the wettability of rock surfaces to make them water-wettable, they enable crude oil to overcome capillary forces, spontaneously permeate and be drawn out of fine pores, and converge into larger pores. In particular, they promote the spontaneous permeation and absorption of crude oil from “dead” pores, thereby increasing single-well production and ultimate recovery rates.
The product is particularly suitable for the fracturing and pressure-driven recovery stages in unconventional reservoirs such as low-porosity, low-permeability formations, shale oil, and tight oil.
Product Features
1. Significantly reduces the capillary resistance of crude oil, allowing it to spontaneously permeate and desorb from fine pores.
2. Based on the spontaneous permeation mechanism of surfactants, it promotes the spontaneous permeation of crude oil from “dead” pores.
3. Reduces the oil-water interfacial tension and alters the rock surface wettability to water-wetting.
4. It accelerates the desorption and effective dispersion of crude oil from the rock, drives the migration of residual oil, improves oil recovery efficiency, and thereby increases the recovery rate.
Capillary Action
Application
The product is particularly suitable for fracturing and pressure-driven recovery stages in unconventional reservoirs such as low-porosity, low-permeability reservoirs, shale oil, and tight oil.

Directions for Use
1. Suitable for unconventional reservoirs such as low-porosity, low-permeability, shale oil, and tight oil reservoirs: ≤50 mD.
2. Preferably used in formations with large swept volumes or as the leading component of fracturing fluids.
3. Suitable for oil-wetting reservoirs; even more effective in water-wetting reservoirs.
4. In terms of process, variable-volume pulsed water injection can be employed; a pulse interval of 10–30 hours is recommended, with 3–4 pulses being optimal.
