Drilling
The service giant shares how its new technology can sense rock properties 50 ft ahead of the bit in horizontal wells.
This paper describes the development of a method of predicting drillstring-friction coefficient during tripping operations that can be used for early warning of stuck pipe.
This paper proposes a time-series analysis approach to build a reliable, easy-to-use tool to automatically detect stuck pipe accurately and early.

By creating a different sort of partnership for a drilling project with close cooperation and greater efficiency built into every detail, including the contracts, Statoil was able to halve the cost of drilling eight wells at its Johan Sverdrup field. -
Along its journey to full-automation, the US drilling sector is facing a series of important crossroads that will determine what the so-called “rig of the future” really will be.

The quick turnaround times and low-risk nature of shale developments need to be replicated in the deepwater business, according to the CEO of Murphy Oil.
-
Multilateral wells with smart completions controlled by different flow-control technologies offer great operational flexibility, with each lateral able to be operated and optimized independently.
-
This paper demonstrates how the latest generation of connections has been tested and validated to extreme loads before being installed in the wellbore.
-
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.

Despite cement’s remarkable properties, the search continues for enhancements in the areas of cost and isolation performance. Efficiencies and enhancements have been explored even to the point of replacing cement with other materials.
