After long-term water injection, mature reservoirs are encountered with the adverse
consequences of the treatment, including erosion, rock formation destruction and drastic …

In recent years, polymer micro/nanogels which are re-crosslinked polymers with 3D
networks, have attracted a lot of interest in Enhanced Oil Recovery (EOR) field. In size of …

Despite rapid advances in renewable energy extraction and utilization, global oil demand
continues to rise. Oil displacement technologies are widely studied and applied because …

Low elastic polymer microsphere (L-EPM) has been proposed as a functional polymer
microsphere these years. L-EMP has the excellent deformation ability in the porous medium …

Polymer gel systems have been widely applied to control excessive water and improve oil
recovery (IOR) in petroleum reservoirs. They are usually divided into two main types, in-situ …

Particle migration in porous media is of great significance in the areas of formation-water
filtration and oil field development. The current theories and methods ignore the effect of …

Heterogeneity is well known to reduce sweep efficiency during oil development processes.
Self-adaptive micro gel (SMG) as a agent for in-depth profile control is significantly limited to …

The oil production rate decreases rapidly after a short period of high yield from acidizing or
fracturing in low-permeability reservoirs. In this paper, nanospheres are applied before the …

This paper presents the results of CDG nano gel based sandpack flooding, IFT and rheology
laboratory measurements. CDGs viscosity had an inverse relation with shear rate, and …

Low elastic polymer microsphere (L-EPM) had been a promising conformance control agent
with the wide application of polymer microspheres. The filtration loss characteristics, core …
