Permeability of Coal Cores with a Drainage Fracture with a Monolayer of Proppant

Permeability of Coal Cores with a Drainage Fracture with a Monolayer of Proppant

The article describes the studies on permeability of coal cores with a through drainage fracture with and without a monolayer of a proppant. The experimental procedure is descried. The parameters of the jointed structure of test long-flame coal are given. The efficiency of wedging drainage fractures...

Description
Summary:The article describes the studies on permeability of coal cores with a through drainage fracture with and without a monolayer of a proppant. The experimental procedure is descried. The parameters of the jointed structure of test long-flame coal are given. The efficiency of wedging drainage fractures by a sparse proppant monolayer in building up permeability of deep-seated coal is demonstrated.
