Description
Qiming Zheng and co-authors (2025) developed gel particles that survive the heat of deep oil reservoirs. In high-temperature fields, injected water finds easy channels and bypasses oil, and the usual gels break down in the heat. Their particles, called DPAG, are built with heat-stable building blocks and a double network of chemical bonds plus electric attraction.
Tests confirmed the particles formed evenly and in good shape. They swelled to nearly fifteen times their dry size and held strength far better than a conventional gel. After thirty days in the heat they had lost under a fifth of their strength. Pumped at low concentrations, they plugged flow paths with up to 98.7 percent efficiency while still moving deep into rock. In core flooding tests they raised oil recovery by 22.4 percent. The authors present DPAG as a strong candidate for conformance control in hot oilfields.
