Case Study Lukoil Saves USD 6.8 Million Using First Extended-Reach Intelligent TAML 5 Multilateral Well
Integrated technologies address numerous technical challenges in challenging oil rim environment in the Caspian Sea.
Well barrier for isolating wellbore and reservoir fluids while minimizing risks
Prevent formation damage and minimize workover costs with isolation valves that safeguard reservoirs by providing a reliable barrier within the completion string. Simultaneously minimize risks by isolating the formation and containing reservoir fluids, which increases efficiency by enabling batch drilling and completion operations.

ISO 28781 and API Spec 19V are international standards that prescribe the requirements for subsurface barrier valves and related equipment for use in the petroleum and natural gas industries. Subsurface barrier valves provide a means of isolating the formation or creating a barrier in the tubular to facilitate the performance of well operations before production or injection starts. Barrier valves are also available for the postproduction or postinjection phase.
