OKLAHOMA: PRODUCTION FORECAST UGcenter.com | November 2018 | 45 the basin include favorable mineralogy, attractive thermal maturities and good availability of well data. On the eastern side of the state lies the Arkoma Basin. The Arkoma Basin is characterized by sub- stantial natural fracturing and faulting. Although this area was quite active in the early years of shale, today it remains relatively quiet. On the northern edge of the state and crossing over into Kansas lies the Mississippian play. The Mis- sissippian could be the most heterogeneous play in North America. To date, it is diffi cult at best to iden- tify any clear sweet spots, or even emerging sweet spot areas in the play. As such, the ability to identify good areas from lesser areas remains a challenge. The Scoop The Scoop is dominated by thick, silica-rich Wood- ford shale characterized by good thickness and high-quality geo-signatures. Continental Resources announced the play in 2012. Similar to the Eagle Ford and Utica plays, the Scoop contains windows for gas, condensate and oil that closely maps changes in thermal maturity. Activity to date has been great- est in and around Grady County, particularly near the transition zone between oil and condensate. Like most unconventionals, the Scoop started life with relatively short laterals of about 4,300 ft in 2012. It wasn't long before operators opted to test various lateral lengths and completion designs. The cumulative result was an increase in the normalized proppant/water usage to 2.1 MMlb per 1,000 ft, an increase of more than 170% from early designs. In time, lateral lengths of 7,500 ft to 7,600 ft gained favor, leading to peak production rates of 1,400 boe/d. Two prizes, the Woodford and the Springer shales, dominate Scoop conversations today. The Woodford—the traditional target in the play—is FIGURE 4. Oklahoma Categories
