Abstract During the unconventional hydrocarbon development. the irregular shaping and uneven sand concentration of proppants banks in the staged multi-cluster fracturing of horizontal wells are key factors determining the fracture conductivity and post-fractured well productivity. To compensate for the limitation of small-scale sand filled core conductivity research that cannot accura... https://www.bekindtopets.com/mega-grab-SDS3113-High-Tea-Single-6-top-grab/
