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).

This paper presents full-scale tests that show it is possible to obtain good cement placement when the tubing is left in the hole.

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.

Momentum is building for what is being called the “peak demand” theory—that before too long global oil demand will begin to fall.

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.

One of the challenges for those involved with understanding an unexpected decline in well performance is identifying the exact causes for the reduced productivity. Consideration of all data available can eventually point toward one factor that could explain productivity decline.

Around the top of the list of ways to make hydraulic fracturing more efficient is by expanding the area that is effectively fractured. There is growing evidence of the need for methods to do this that are cost-effective, reliable, and repeatable in wells that vary widely.

Following my theme for the year on risk and reward, this month’s column looks at how partnerships affect the risk/reward balance. Our industry is full of partnerships—it’s how we share the risk in a very risky business.

The unique properties of deepwater formations pose significant ­challenges to the capabilities of conventional drilling rigs. Using automated drilling equipment, including MPD, efficiency and cost savings can accompany safety.

With an uncertain future spawning from the Brexit referendum, the British government is seeking to maintain as much consistency in its energy policy as possible.
