Problem Solution:
Decline in production rate of producing wells and injectivity of injection wells equipped with small‑diameter liners (102 mm, 114 mm), with zenith angles up to 92°, in low‑permeability reservoirs (ANPD), caused by blockage of the perforated interval in the productive formation by plugs of various origins.
