Drilling
The company said that its AD-300, a 50-m-high automated island drilling rig that walks between wells, was delivered 3 months ahead of schedule.
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.

For the past quarter of a century, underbalanced drilling (UBD) has been a niche technology known to many and practiced by few. It has seen acceptance in the North Sea, where UBD is used to drill through depleted reservoirs. -
There are headlines every day that discuss the ethics and safety behind oil and gas operations, particularly hydraulic fracturing.
-
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.
-
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 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.

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.

In order to avoid some of the detrimental effects of formation damage, a key aspect is laboratory testing of representative core material under representative downhole conditions.
