We continually test new technologies that reduce our environmental exposure and risk. We use dissolvable plugs or dissolvable ball and sleeve completion systems during hydraulic fracturing for intra-stage isolation, reducing the need to drill out or remove the plugs or balls. Instead, they dissolve with time in the downhole environment. Using dissolvable technology increases the safety of our employees by reducing the number of well clean-outs in high-pressure conditions.
At the end of 2015, 40 of 50 wells in our Rockies assets were hydraulically fractured using dissolvable technology. In 2016, 100% of our wells will be utilizing dissolvable technology in North Dakota and Utah. We also plan to utilize dissolvable plugs on many of our wells in the Mid-Continent where feasible based on the downhole environment.
