Statoil is going to work to put its enormous Johan Sverdrup discovery into production, showing that even one of the most explored parts of the North Sea still has significant potential.

In a down market, plugging and abandoning North Sea wells looks like an opportunity. The cost for operators is reduced because the government is paying more than half of the cost of the work, and many service companies hungry for work are offering discounts.

This paper presents experimental research in which a significant fracture-pressure increase was achieved in shale and the predominant wellbore strenghtening mechanism was identified.

The technology described by the authors provides the simplicity of a single-step distillation process for the separation of CO2 from natural gas. The technology has shown the potential to separate CO2 and other impurities from natural gas more efficiently and more cost-effectively.

Shale-gas resources were explored in Saudi Arabia by adopting a “technology-driven” approach against the US-based approach that might be termed the “factory” or “statistical” approach.

Conventional wisdom implies that natural-gas demand will continue to grow, especially in locations where coal is being phased out, nuclear growth has slowed/reversed, and renewables remain a small and intermittent energy source for the foreseeable future.

Liquid loading is a common production problem in mature gas wells. Correct prediction of the critical gas velocity at which the well starts to load is very important for taking action to prevent premature loss of production.

This paper offers insight into an integrated effort at combining analytical information, numerical well-test models, and geological evidence to explain the reservoir behavior observed in the Huntington field.

For thin-oil-rim reservoirs, well placement, well type, well path, and the completion methods must be evaluated with close integration of key reservoir and production-engineering considerations.

This paper gives the recommended MSF horizontal-well spacing for several development scenarios in Saudi Arabian gas-reservoir environments.
