Drilling
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 guest editorial addresses the need for high-temperature directional drilling technologies as the number of rigs used to develop next-generation geothermal wells is set to rise in the coming years.

Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed. -
Wellbore position is computed from survey measurements taken by a measurement-while-drilling (MWD) tool in the bottomhole assembly (BHA).
-
Cementing is central to the discussion of zonal isolation and well integrity.
-
Saudi Aramco operates a large offshore oilfield development that has driven achievements in multilateral and extended-reach directional wells.
-
Eight of the world’s 10 longest wells have been drilled by ExxonMobil as operator of the Sakhalin-1 project in Russia.
-
This work demonstrates cement design that includes evaluating cement-sheath mechanical integrity in intercalated salts.
-
Operators in the North Sea have been concerned about the ability of the cement sheath to maintain sealing integrity because of the increasing number of reported failures in mature wells. This paper presents results from a new laboratory setup to visualize the source of issues.
-
Many wells in the Cana-Woodford shale suffer from chronic sustained casing pressure (SCP) because of poor cement-sheath bonding.
-
The development of multilateral wells and long-reach wells has become important to maximizing recovery for many fields. These technologies are often applied in offshore environments, where large reservoir areas are drained from one or more platforms.
-
Automated particle-size analyzers are something you will not see on most drilling rigs, but some think this outside-the-oil-field technology will play a big role in the future of the drilling sector.
