Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.

A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.

I am disappointed to see public opposition to hydraulic fracturing, because I think, for the biggest part, it is unfounded. It would be inaccurate to deny that there can be problems. But an objective look reveals that its benefits far outweigh its potential risks.

US companies began selling crude oil on the international market last month shortly after the US Congress ended the country’s 40-year-old ban on oil exports.

This work presents a real field example in which the integration of well-testing and geological interpretations increased the understanding of a complex, heterogeneous reservoir.

Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.

Although the wellbore is in a nonisothermal environment, heat transfer between the fluid in the wellbore and the formation is often ignored and temperature is usually assumed constant in data interpretation, which will lead to misunderstanding of the pressure profile.

Developers of the latest generation of unconventional hydraulic fracturing models are hoping that current weak oil and gas prices will generate newfound interest in their software technology.

Without serious climate policy restrictions, the use of cheaper oil will likely grow and extend its life expectancy throughout the global energy system.

It was my pleasure to go through 169 papers submitted to SPE in this field over the past year and select three for inclusion in this issue as well as three for additional reading.
