Controlling Preferential Water Flow Through Crosslinked Polymer Systems

Chemical System: Anionic Polyacrylamide + Phenolic Resin Crosslinking System

Challenge

In high-water-cut oil wells, preferential water flow and heterogeneous reservoir conditions can significantly affect production performance.

Solution

A crosslinked polymer gel system was applied for water shutoff and profile control to improve flow distribution within the formation.

Result

Water cut reduced from 99.3% to 82.1% and from 98.4% to 65.5% in reported wells, with effective water-control and oil-increasing performance.

Improving Oil Displacement Through Surfactant–Polymer Systems

Chemical System: Surfactant + Polymer Alternating Injection

Challenge

Improve reservoir displacement efficiency by modifying interfacial properties and controlling fluid mobility.

Solution

Surfactants and polymers were alternately injected to improve oil displacement and mobilize remaining oil.

Result

Oil production increased to about 5.8× pre-treatment level; overall water cut fell 6.3 points; 83.3% effective response rate across 24 treatments.
