HOUSTON, Feb. 18 -- Enventure Global Technology used its solid expandable tubular technology to install a 3,068-ft, 13-3/8 x 16-in. open-hole liner (OHL) in an ExxonMobil Corp. well in the Caspian Sea off Azerbaijan.
It claimed a length record for the system and called it the Caspian's first solid expandable.
Enventure said ExxonMobil included the OHL system in its original casing design to avoid borehole tapering, as formations to be penetrated demanded more casing strings than conventional pipe allowed.
Caspian Sea wells frequently encounter high formation pressures, multiple pressure regressions, and narrow margins between formation pressure and fracture gradient.
