Drilling
A report commissioned by Havtil, the Norwegian Ocean Industry Authority, calls for better dialogue regarding pore-pressure uncertainty and higher-end drilling techniques like managed pressure drilling as methods to reduce the risk of well-control events.
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.

West Africa has seen a significant shift in drilling activity, mainly in deep water. Many of the major international operators are carrying out important exploration-and-development activities there. -
One of the defining features of the 21st century will undoubtedly be the changing relationship between humans and automated machines.
-
The development of conventional reservoirs has typically involved minimal logging-while-drilling (LWD) technology, usually consisting of survey, gamma ray, and possibly resistivity tools.
-
A new measurement-while-drilling (MWD) tool has been designed that can operate reliably at 200°C and 207 MPa, providing real-time direction and inclination surveys, azimuthal gamma ray, annular and internal pressure while drilling, and shock and vibration measurements.

Looking after the human factors in daily operations is good business because it increases employee safety and improves work performance.

This paper describes the planning and execution of use of mud-cap fluid in the drilling of an ultranarrow-margin (0.50-lbm/gal window at the planning stage) high-pressure/high-temperature (HP/HT) well from a jackup rig.
-
The Burgan reservoir consists of vertically stacked channel sands along with a fault network connected to the aquifer and contains highly viscous reservoir fluid.
-
The paper discusses two gas/condensate-development projects offshore Vietnam that deploy managed-pressure-drilling (MPD) technology.
-
Approximately one-half of all offshore conventional oil and gas resources are known or thought to be undrillable with conventional, open-to-atmosphere circulating fluids systems for safety, economic, and/or technical reasons.
-
This study concerns the mature Gyda reservoir, where some recent production wells have underperformed relative to equivalent initial wells.
