Drilling
Developing the theory of mechanical specific energy from the perspective of instantaneous drilling power rather than the compressive strength of the formation leads to an improved understanding of drill-bit mechanical efficiency.
The oilfield service company will supply power plants capable of electrifying 180,000 US homes with geothermal energy.
This article is the fourth in a Q&A series from the SPE Research and Development Technical Section focusing on emerging energy technologies. In this piece, David Reid, the CTO and CMO for NOV, discusses the evolution and current state of automated drilling systems.
-
A North Sea field development included installation of long 4½-in. completion liners in the horizontal reservoir sections of each well. To minimize overall risk, the operator planned to use managed-pressure drilling (MPD). -
A field well was designed, built, and used to demonstrate the concept of real-time monitoring of the flow of drilling mud and smart cement and the hardening of the cement in place.
-
This paper discusses an expandable-liner-hanger (ELH) system that provides liner rotation during the liner deployment and the cementing operation while providing a hydraulically energized liner-top seal upon setting.
-
Norway’s Statoil on 24 April played down concerns that drilling in the Arctic is risky, days before it starts its drilling campaign in the Barents Sea, where the country believes around half of its remaining resources could be located.
-
Aggressive drilling growth in the Permian and other shale plays belies the cost of those wells, which in many cases are in the red.
-
Deepwater operators continually face technical and environmental challenges to drilling and completing wells safely and efficiently.
-
This paper focuses on the application of radio-frequency-identification technology to enable an operator to eliminate an intervention run (or intermediate liner) for a 10,000-ft reservoir section.
-
One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost.
-
Pore-pressure prediction plays an important role in well planning as exploration targets shift to deeper, overpressured reservoirs.
-
The industry has developed a deep and healthy respect for systems-engineering processes and the associated full considerations during the deployment of new technologies. The result has been a significant improvement in the successful use and broader deployment of these attractive technologies.
