Bone Spring, but it will be an enormous play. The Delaware Basin is geographically large, covering over 5 million gross acres with seven zones being drilled as potential targets.” Bone Spring Focus Denver-based Cimarex Energy Co. is one of the independent companies putting its primary Permian focus on the Bone Spring, on both sides of the Texas-New Mexico border. “We have 14 rigs running in the Permian Basin,” explains Mark Burford, vice president of capital markets and planning for Cimarex. “Half of our rigs are operating in the Bone Spring in New Mexico (in Lea and Eddy counties) and three are drilling in the Bone Spring in Texas.” He says Cimarex had drilled 106 gross and 80 net wells through the third quarter of 2011. “I expect we will get to 115 gross and 105 net wells by the end of the year,” Burford projects. Cimarex also has one rig dedicated to drilling vertical wells in the Paddock/Blinebry or Yeso play on the New Mexico Shelf, according to Burford. Calling the Delaware Basin “a large area with different variables,” he says the Bone Spring is primarily an oil play, producing 82 percent oil as well as liquids-rich gas. For example, Cimarex has been drilling horizontal wells primarily in the Second

Concho Resources has expanded from a startup company in 2004 to become the sixth-largest oil producer in the Permian Basin and the largest oil producer in New Mexico. One of the company’s core plays is the Yeso on the New Mexico Shelf. Shown here are drilling operations on Concho’s 1,000th Yeso well.

oil and gas assets last year, giving Concho what Leach described as a “three-legged stool” of exploration and production plays: the Yeso oil production in New Mexico that has been the company’s “bread and butter,” the Wolfberry play in the heart of the basin surrounding the Midland/Odessa area, and the emerging Bone Spring play in the Delaware Basin. By retaining Henry Petroleum’s employees after that acquisition, Leach says Concho’s employees now have drilled more than 1,000 wells in the Wolfberry. Last year’s $1.6 billion Marbob acquisition consisted of half Yeso and half Delaware Basin assets, all in New Mexico. “Johnny Gray of Marbob drilled the first horizontal well in the Bone Spring,” Leach notes. “We were able to retain Marbob’s technical personnel, which gives Concho a leg up as we begin to explore and develop the Bone Spring.” Concho Resources has kept 36 rigs running this year in the Permian Basin, according to Leach, with 12 rigs operating in the Yeso, 17 in the Wolfberry, six in the Bone Spring and one rig that is drilling horizontally in the Abo play north of the Yeso in New Mexico. In all three of Concho’s main play areas, Leach says the company is producing about two-thirds oil and one-third natural gas, which has “a lot of liquids in it.”

Leach says the industry now has 90 rigs running in the Bone Spring in the Delaware Basin. “We still are trying to determine which zones will be most productive in the Bone Spring,” he reports. “There is a lot of science required in the

Cimarex Energy has 14 rigs running in the Permian Basin, nine of which are operating in the Bone Spring play in New Mexico and Texas. As of mid-November, Cimarex had drilled 65 wells in the Bone Spring, drilling to vertical depths of 8,000-9,000 feet and then making the turn to drill 4,500 feet laterally through the formation. The 30-day gross production from the company’s New Mexico Bone Spring wells averages 510 bbl/d equivalent (83 percent oil), and the Texas Third Bone Spring wells average 660 bbl/d equivalent (74 percent oil).
