One of the key enabling technologies involved with modern Arctic-going vessels is the azimuth thruster. Azimuth thrusters are favored by the cruise industry because they can be tilted at different angles, which reduces propeller-induced vibrations and shock loads on a ship’s hull, allowing passengers to enjoy a quieter voyage. But in the Arctic, azimuth thrusters have…

Although global crude oil production has declined in some regions since the collapse in oil prices began, and there have been massive cuts in company spending, world output has remained stubbornly resilient

The industry’s experience thus far drilling offshore the Arctic is a powerful argument to build a new generation of vessels and drilling rigs purpose built for operations in heavy ice.

Andrew Vaughan, Shell vice president for Abu Dhabi, Kuwait, and Syria, and country chairman for Abu Dhabi, discusses how his company is promoting technology and innovation in the Middle East.

As oil fields throughout the world are reaching maturity and requiring the use of secondary and tertiary recovery techniques, oil companies are looking for new processes and technologies to extract more oil from these aging fields.

Semisubmersible floating production systems (SFPSs) with steel catenary risers (SCRs) are attractive field-development solutions, especially in deeper water of Western Australia. However, SCR design is challenging in the offshore Western Australia environment because of severe cyclonic environments.

The full-field development plan for the Khazzan project in Oman is based on drilling approximately 300 wells targeting gas-producing horizons at measured depths of approximately 6000 m with 1000 m horizontal sections.

Although the use of managed-pressure drilling is helping drilling operation by allowing better pressure control in the annulus, there are also new risks to be taken into consideration.

Pressurized-mud-cap drilling (PMCD) and early kick detection (EKD) are two unconventional drilling techniques that have been used widely individually, mostly in relation to closed and pressurizable systems and to managed-pressure-drilling (MPD) applications.

Smart waterflooding by tuning injection-water salinity and ionic composition has gained attention in recent years. In this study, desalination technologies are reviewed with the objective to develop potential water-treatment solutions that can most efficiently alter injection-water chemistry.
