Drilling
The company said that its AD-300, a 50-m-high automated island drilling rig that walks between wells, was delivered 3 months ahead of schedule.
A report commissioned by Havtil, the Norwegian Ocean Industry Authority, calls for better dialogue regarding pore-pressure uncertainty and higher-end drilling techniques like managed pressure drilling as methods to reduce the risk of well-control events.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.

This work demonstrates cement design that includes evaluating cement-sheath mechanical integrity in intercalated salts. -
Many wells in the Cana-Woodford shale suffer from chronic sustained casing pressure (SCP) because of poor cement-sheath bonding.
-
The force required to drill through a rock is a direct test of its strength and stiffness. Developing a reliable measure of the properties of rock based on the force required to drill a long lateral is a large challenge.
-
What is observed when an unconventional well is fractured is often at odds with what was expected by those who planned the job.
-
The operator of an offshore jackup rig in the North Sea required safe and efficient deployment of the completion string without killing the well during tripping.
-
Many of us work in strong functional environments, where all too easily we can deploy solutions that have the potential for repercussions on other aspects of well design, construction, completion, and performance.

The Shearwater field is a deep, high-pressure/high-temperature (HP/HT) reservoir located in the UK Central Graben of the North Sea.

A pilot project carried out by Hess demonstrates how quickly automated drilling technology is able to take a rig from the bottom of the pack in terms of performance and push it to the top.

This paper discusses the first multilateral well with a Level-4 junction combined with an inflow-control device (ICD) planned, designed, and drilled in the Upper Burgan reservoir of Raudhatain field, north Kuwait.

As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.
