A simple and effective experimental method is proposed to simulate coal fines migration through the proppant pack; such migration inevitably occurs during the process of fracturing fluid flowback or dewatering and gas production in coalbed methane (CBM) reservoirs.

An experimental study of coal-fines migration in Coalbed-methane production wells
Journal of Natural Gas Science and Engineering, 2015Abstract Coalbed Methane (CBM) has become an important gas resource in the last several decades. The brittle property of coal matrix and overflushing operation make the migration of coal fines inevitable. As the liquid flows below a critical velocity, the coal-fines accumulate in the bottomhole.

Abstract Both fines migration and creep can damage coal permeability during coal seam gas production. This study investigates the individual and coupled effect of fines migration and creep on coal permeability. We perform three types of flow experiments on coal samples: (1) water flow with both fines migration and creep, (2) gas flow with creep and ...

Drilling through coal beds and high initial fluid production rates can lead to shear and compressive failure of coal, resulting in the creation of coal fines. In overbalanced drilling, these fines mix with the drilling fluid and are carried into the near-wellbore zone. During initial water production, the fines are transported to the producing wellbore
