Drilling
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 study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.

The only wells that are straight or follow a smooth curve are in the pictures in well plans. Real wellbores are shaped by the mechanics of directional drilling tools, the skills and attention of drillers, the force of gravity, and the path followed by hydrocarbon-rich seams of rock. -
With the innovation of extended-reach and directional drilling, running casing and liner strings has become increasingly difficult.
-
While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.
-
The understanding and proper application of rotary-steerable systems will continue to provide a step change in the way fields are developed. Technology developed and implemented during the boom will receive closer scrutiny and evaluation during the bust.

Drilling the Severnaya Truba field in Aktobe, Kazakhstan, has been costly and time consuming.
-
Vimlesh Bavadiya is leading a team of engineering students at the University of Oklahoma (OU) to repeat its victory in SPE’s Drillbotics competition next year.
-
Despite hostile wellbore conditions, an operations team overcame challenges of drilling-fluid design and management to drill the first ultrahigh-pressure/high-temperature (HP/HT), deep-gas well offshore Malay Peninsula.
-
In an effort to optimize drilling operations and economics, an operator examined the effect of adding hollow glass spheres (HGSs) directly to the drilling fluid instead of performing underbalanced drilling.
-
The strength and conductivity of proppant packs are key parameters for assessing their performance. This paper introduces a new analysis technique based on interpretation of acoustic measurements to quantify mechanical damage in propping agents.
-
This paper presents experimental research in which a significant fracture-pressure increase was achieved in shale and the predominant wellbore strenghtening mechanism was identified.
