Well integrity/control
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 paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.

Well control training programs for deepwater drillers and key rig personnel are undergoing a major overhaul that has been years in the making. -
More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
-
Offshore drillers have been battered by the plunge in oil prices with falling day rates and a growing number of older rigs headed for demolition.

An ongoing research project started nearly 3 years ago by the US Department of Energy’s National Energy Technology Laboratory (NETL) is shedding new light on what really happens to foamed cement as it is pumped deep down offshore wells during completions.

From 2009 to 2010, there was an increase in the number of well-control incidents on the Norwegian continental shelf reported to the Petroleum Safety Authority Norway (PSA).
-
A scientist hired by federal regulators to look for ways to reduce the risk of well blowouts said it is time for the oil and gas industry to treat kicks taken while drilling the same way doctors treat heart attacks.

In response to the 2010 Deepwater Horizon incident that claimed the lives of 11 men and led to the worst oil spill in United States history, the offshore industry devised new technologies and methods that would allow for a quicker response in the US Gulf of Mexico.
