Mechanism of action of water-locking agents: Solving the water-locking problem from multiple dimensions

The reason why water-locking agents can effectively relieve reservoir water-locking damage and restore and improve reservoir permeability lies in the synergistic effect of multiple mechanisms, which solve the water-locking problem from multiple dimensions such as improving fluid properties, adjusting reservoir…

Oilfield decongestant technology system, classification and mainstream type application strategy

In the mid-to-late stages of oilfield development, reservoir blockage has become one of the core issues restricting production capacity. Whether in conventional sandstone reservoirs or unconventional tight reservoirs, during long-term water injection development, fracturing, or production operations, factors such as…
