The largest of Concho's core areas, our Delaware Basin position, which includes our asset on the New Mexico Shelf, spans 640,000 gross acres. The Delaware Basin is a large geographic area spanning the southwest corner of New Mexico and parts of west Texas.
The Delaware Basin has rapidly advanced from an exploration play to large-scale development and some of our best projects are here. We continue to optimize lateral placement, completion techniques and well spacing to maximize recovery from the prolific multi-zone resource. The move to manufacturing-style development, combined with application of advanced technology is accelerating innovation and improving productivity. We remain focused on high-grading the Delaware Basin position through asset trades to further block up acreage for drilling long-laterals and manufacturing development.
