Novel flexible pipe overcomes challenges in pre-salt subsea developments

Andre Macedo, Mauricio Brandao, Baker Hughes

An innovative technological solution has overcome flexible pipe corrosion cracking in high CO2 content fields, including Brazil’s pre-salt offshore developments. The new pipe system is verified to extend service life by at least 50%, compared to standard flexibles.

U.S. operators working down DUC backlog

Craig Fleming, World Oil

Despite a modest reduction in the DUC inventory, there are still 7,086 wells waiting on completion. With the industry in disarray, it has become increasingly likely that many of these horizontal boreholes may never be completed.

Machine learning for predicting stochastic fluid and mineral volumes in complex unconventional reservoirs

Fred Jenson, Chiranjith Ranganathan, Shi Xiuping, Ted Holden, CGG

A machine learning workflow can quickly, and accurately, predict mineralogy, porosity and saturation in multiple wells to better understand productive layers in unconventional oil reservoirs.
