Engineering Report of PJSC «Orenburgneft» on the Results of Pilot Industrial Testing (OPI) of the Horizontal Well Cleaning Complex (KOGS) PS‑238
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.
Result:
... It has been confirmed that the time required to bring producing wells to operating mode has been reduced by a factor of 5.2...
... rollout is planned for 2018, with a target of 50 operations at PJSC «Orenburgneft»...
