Since the last report, the well has been drilled ahead in 121/4 inch (311 mm) hole to a section depth of 882 metres and the 9 inch (244 mm) casing string
has been run and cemented to 880 metres.
The major advantage of casing centralizer is protection of casing string
and reduces drag when running casing.
Rather than extending a single casing string
to the top of the wellbore, the technology enables suspending the liner below the ground.
Houston, TX, November 12, 2018 --(PR.com)-- Abrado Successfully performs two complex dual casing string
windows using its proprietary Medusa[R] Expandable Section Milling Technology for Super Major on International P&A project to mitigate sustained casing pressure.
Meanwhile, at Opuama-11, the OES rig has drilled the well to the total vertical depth of 7,914 feet and the final casing string
has been run and cemented.
Then, build a stress field calculation model and analyze the stress status of steam injection string and the casing string
in the well.
Then, the dummy steel casing is attached to the cradle boring machine by placing the casing string
into a cradle on the front of the machine.
After drill bits were advanced 600 feet past the casings, specialized casing driver adaptors were used to add 300 feet of wash-over casing to each platform's casing string
The 01RX Cobalcescu South Exploration well in Block EX-28 Est Cobalcescu, offshore Romania, is at 1,629 metres and cementing the 13 3/8" intermediate casing string
. The well is evaluating the hydrocarbon potential of Pontian (upper Miocene) aged sands at various levels.
After the setting of the intermediate casing string
, the plan was to drill and evaluate three primary targets in the Cretaceous, with a Shiranish Fm being the uppermost prospective reservoir.
