Asphaltenes represent the heaviest fraction of crude oil, which are known to precipitate when the crude is added to aliphatic solvents such as n-pentane or n-heptane and yet remain soluble in light aromatic solvents such as benzene or toluene.

The 2-year downturn in oil prices has been a challenge for operators and service companies alike, but operators appear to have turned a corner, going by the most recent fourth-quarter earnings.

SPE President Janeen Judah writes, "When the upturn occurs—and it will happen—are we ready to move forward with a next-generation workforce?"

The current oil and gas commodity prices have posed several challenges to oil and gas companies operating in shale plays trying to generate revenue or even becoming cash neutral.

Early testing suggests that grains of proppant so small they need to be measured in microns can add production by slowing the notoriously rapid declines in unconventional wells.

Industry trends in production monitoring and surveillance continue to demonstrate significant input from the academic and research fields, practical applications, and new-technology introduction. Market conditions similar to those of the previous year are driving some of the same discussions.

With newly discovered fields and the extension of existing areas, the challenges related to reservoir heterogeneity, tight rock, layered systems, and field maturity have led to innovative ideas and to testing and application of technologies.

Advancement of the integration of seismic with other oilfield disciplines has been fueled by two factors. First, advances in seismic technologies naturally led to more-powerful integration. Second, developments in seismic were motivated in direct response to the needs of interpreters and engineers.

Cost optimization in heavy-oil production can be achieved through numerical modeling to suggest general optimal strategies and development plans or by using proper real-time data acquisition … for prompt decisions while operations are ongoing.

Recent studies have found that the viscosities of borate gels at actual downhole pressure conditions may be 80% less than those from standard high-pressure/high-temperature rheometer measurement (which uses 400-psi top pressure).
