DOI: 10.1016/j.petrol.2020.107799
Abstract: Abstract In the early production stage of coalbed methane (CBM) wells, especially in low permeability reservoirs, the method of shutting in casing annulus is usually adopted. However, the current commercial numerical simulation software fails to… read more here.
