.... On this basis, the effects of particle size, flow rate, and concentration on the blockage performance were discussed. Yao et al. (2012 ) and Li et al. (2019 ) investigated the migration and shunt flow characteristics of polymer microspheres and revealed the deep conformance control mechanism. Based...

... the effect of sediment particle size and type of promoter on the kinetics of the methane hydrate formation and dissociation in the combined system. Environment-friendly amino acids (L-valine, L-methionine & L-histidine) and surfactant Sodium dodecyl sulfate are used as a promoter with four different...

... interface for all τ, depending on the boundary configuration. For arrays of packed spheres Λ = 3 16 , attains the most accurate boundary representation ( Khirevich et al., 2015 ). fracturing materials fracturing fluid Simulation particle size complex reservoir concentration profile...

... 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...

... with reasonable properties and favorable particle size distribution (PSD) were designed to meet the challenging task of MRC drilling. MRC wells have proved their success as a productivity enhancement and economical option for field development in Saudi Arabian fields. 4 The objective of the study...
