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.

This paper describes experiences, challenges, and approaches to solving the problems related to creating an advanced early kick-detection system suitable for floating mobile offshore drilling units. -
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.
-
Implementation of new technology can require that leadership and key team members be willing to step outside their comfort zones.
-
Large areas of the North Sea contain Cretaceous sediments, which form a massive hard layer of chalk that historically has presented a major drilling risk and expense to operators in the area.

Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.
