OKLAHOMA: TECHNOLOGY 28 | November 2018 | hartenergy.com produce natural polymers that can then be func- tionalized to become specific types of oilfield chem- icals—surfactants, clay control agents, etc. Again, what we are looking for is chemistry that creates the performance that's required firstly and also has a more benign, tolerable impact on the environment itself. We are all about both of those things." SpringBoard to success Oklahoma-based Continental Resources generates 39% of its 287,000 boe/d average production from the region's Scoop/Stack area. Scoop/Stack pro- duction is up 26% compared to early 2017. One of the marquee projects for the operator in the area is the recently announced Springer devel- opment located on 70 sq miles of contiguous lease- hold in the Scoop. "For us, we're probably most excited in Okla- homa about the efficiencies we expect to see from our SpringBoard project," said Gary Gould, senior vice president of production and resource devel- opment for Continental. "While the term Spring- Board is emphasizing the Springer zone in the Scoop, Springer is really just Phase 1 for us. Under- lying the Springer is Phase 2, which is our Sycamore and Woodford development." Continental is going to ramp up to five rigs running in the Springer, and it is expected to take the company about three to four years to complete the Springer program, according to Gould. "Some- thing that a lot of people don't always recognize is that the Pyle well in our SpringBoard project is actually a Woodford oil well. The Pyle is sig- nificantly outperforming our current Woodford oil type curve, which already has been improv- ing over the past few years," he said. "So we are also looking forward to developing the Sycamore and Woodford when we enter Phase 2 of Project SpringBoard. Concentrating five rigs here, along with associated completion crews, is expected to develop additional cost efficiencies for ourselves as well as our service companies, because we are concentrated in one area where we own approxi- mately 75% working interest in our operated units. So that is a real positive." The Pyle well, located southwest of Continen- tal's Triple H Unit, boasted a 24-hour IP of 1,812 boe/d (81% oil). Early results from the Triple H Unit have seen four wells with 2-mile laterals com- bine for a 24-hour IP of 6,065 boe/d (88% oil). "On these more recent Woodford oil wells, we are completing these laterals with around 180- to 200-ft stages, and about 2,000 to 2,500 pounds per foot of sand," Gould said. "We are continuing to test tighter cluster spacing so we can get more entry points along the lateral. Obviously, our comple- tions do continue to improve over time. Our type curve has increased from 855,000 boe in 2015 to 1.5 MMboe in 2018, and our Pyle well is doing even better. These production improvements have been generated through a combination of longer lateral lengths and optimized completion technology." Project SpringBoard is said to hold up to 400 MMboe of resource potential. Phase 1 will consist of about 100 Springer wells. Phase 2, the Wood- ford/Sycamore development, is targeting about 250 wells. Continental's well design on the Scoop Woodford eliminates the need for an intermediate casing string and reduces well cost by $1 million to $11.7 million per well, such that the econom- ics generate a 70% rate of return based on $65/bbl West Texas Intermediate and the 1.5 MMboe type curve EUR. Getting wired One technology application that has continued to proliferate through the Scoop/Stack is the use of fiber optics or wired pipe designed to gather new data on well performance and other subsurface details. Operator Newfield Exploration has been a champion of fiber optics use, most recently with its 12-well, four-pad Velta June Meramec devel- opment, which featured an assortment of fiber optics and high-resolution pressure monitoring. Although permanent operations for fiber optics is ideal, it is not the only worthwhile application. "Apache has not run permanent fiber optics in our Scoop/Stack play yet," said Rana Roy, drilling and completions manager for Apache. "But we have run fiber optics in some wells post-frack- ing operations and also after the well had been producing for some time on coiled tubing. It is not the best way to monitor continuous well per- formance, but it gives us a good snapshot at that
