During the process of steam thermal recovery heavy oil, channeling seriously affects production and ultimate recovery. In this study, fly ash was used as plugging agent, then a series experiments based on results two-dimensional (2D) were conducted to study effect breakthrough channels. The experimental show that inorganic particle agent made from had good suspension stability, consolidation st...

Orphaned oil and gas wells are abandoned for which the cost of environmental impacts usually falls on governments general public. Government agencies responsible well plugging often face funding shortfalls many orphaned remain unplugged. To address this support natural industry, federal already spending, or considering billions dollars to plug wells. Here, we analyze data United States Canada i...

Steam is essential in petrochemical industries for the transportation of thermal energy and usage some reforming process. Superheaters are heat exchangers that convert saturated steam to dry by utilizing waste from flue gas stream. Medium pressure superheaters prone tube deterioration due service at elevated temperatures erosion presence liquid phase steam, leading plugging after failure. This ...

Abstract Polymers with shape memory property and gel resistance to high temperature can be both used for plugging formation, but they also have shortcomings. Nevertheless, it is possible mix polymer(SMP) particles in the solution use formation stimulate them complete morphological transformation achieve purpose of plugging. This mutual combination method help reduce shortcomings between each ot...

The transport and placement characteristics of proppant in rough fracture is great significance for optimizing fracturing parameters making to the deep part effective support. This paper scans surface morphology rock samples after fracturing, generates based on scanned data, uses high-order interpolation function generate with different roughness, establishes a numerical model roughness Euler-E...
