“Purple Haze” changed the landscape for rock guitar by introducing the world to an unparalleled talent in Jimi Hendrix. Similarly, Eclipse Resources’ Purple Hayes super-lateral in Guernsey County, Ohio, announced the Utica Shale in a major way when the company released the well’s figures earlier this year.
The well is the largest onshore horizontal lateral ever drilled in the country. It has a total measured depth of 27,048 ft that was drilled in less than 18 days, with a completed lateral extension of about 18,500 ft.
The State College, Pa.-based company has been rapidly expanding its lateral lengths—from 2013 to 2015, lengths increased 200% from 6,000 ft to 13,500 ft, according to Oleg Tolmachev, Eclipse’s senior vice president of drilling and completions, who spoke at Hart Energy’s recent DUG East Conference & Exhibition.
This figure is increased even more when Purple Hayes is factored in, jumping to 300%.
The total drilling and completion costs for the well were $850 per lateral foot, which Tolmachev said will improve well economic costs in the region.
“Drilling a super-lateral creates a huge step change…by making the area more economical and resilient in a low commodity price environment. We expect 20% to 30% improvement in [finding and development] F&D costs by reducing the number of vertical penetrations to develop the reservoir, which will reduce the associated costs such as well pads and rig movements,” he said.The rest of this article is available by clicking here.
