In Colombia, the Schlumberger Drilling Group Petrotechnical Engineering Center provided well placement services and proprietary workflows on a horizontal well with complex lithology in the Apiay field for Ecopetrol. The integrated solution included use of PERFORMView* real-time drilling visualization, collaboration, and analysis software. The well was drilled and placed as planned, without sidetracks or lost-in-hole events.In Alberta, Canada, Schlumberger Managed Pressure Drilling (MPD) services were used for Shell to reduce well drilling times in the Duvernay unconventional gas play. The horizontal sections of these wells have narrow pressure windows and extend to lengths beyond 7,000 ft. In order to overcome these challenges, the application of engineered MPD as part of a larger set of improvements to well design has helped Shell improve drilling rates by up to 124%.
