Well integrity/control
This paper describes an automated workflow that helps mitigate sanding caused by excessive drawdown by determining the minimum tubinghead pressure.

Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
This paper presents the characterization and comparison of a metakaolin-based geopolymer as a candidate treatment for remedial operations in oil and gas wells versus conventional state-of-the-art materials.

A large mature onshore Saudi Arabian oil field is producing sour crude oil that multiplies well-integrity challenges. -
The authors describe the development of well-control techniques that allowed successful drilling operations in the Piloncillo Ranch lease in south Texas.
-
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.
-
Making hole has become a more difficult and complex operation as operators move into untapped horizons, especially deepwater and unconventional fields.
-
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.
-
The offshore industry has taken another step toward opening up new deepwater frontiers to exploration with Maersk Drilling ordering the first 20,000-psi blowout preventer (BOP) made by GE Oil and Gas.
-
Many problems that result in BOP downtime could be prevented if only drilling contractors knew which parts of the subsea system to replace and when. BOP monitoring systems have been developed to increase reliability by enabling preventive maintenance.
-
Statistics on well-integrity incidents are difficult to find in the literature. There are some examples of kick and blowout events, but normally they are scarce and focus on the number of incidents and their root causes.
-
The purpose of this work is to investigate typical fracture and collapse models with respect to accuracies in the input data.
