... have good physicochemical performance and transport ability in porous media. According to the reservoir adaptability evaluation, the matching relationships between particle size and core permeability is obtained, to provide guidance for field application scheme. By using NMR andCT techniques, its micro...

... surface and characteristic of the mineral surface affects the nucleation kinetic. Additional factors such as interface-specific area, pore-volume, and pore size distribution are connected with particle size. Therefore, the particle size of unconsolidated media is expected to play a critical role...

... on-the-fly and bullheaded into the wellbore as it will not invade the rock matrix because of particle size. Treatments are usually pumped in stages because the fracture, void, or fissure capacity is unknown. Ideally, placement of the WSP system should reflect an increase to pressure, which is an indication...

... to determine whether or not PPGs reduce the permeability of low-permeable rocks. Daqing (DQ) gel was used as a PPG sample for our filtration experiments. DQ is a strong gel particle with an elastic module of ~6500 Pa at 1% of NaCl (wt%). The particle sizes of the gel ranged from 30 to 120 meshes. Filtration...

... of polymer based drill-in fluids and dry bulk of sized calcium carbonate in terms of return permeability determination, change in particle size distribution, and weight loss. Results indicated that the generated acid mainly targeted fine particles of calcium carbonate present in drill-in fluids and dry bulk...
