"What separates EOG from other operators is how it looks at source rock stimulation. Operators have historically thought the deeper fractures would produce the most resource as it intermingled with the existing fractures. EOG is focusing on creating fractures close to the horizontal leg. Not only would the pressure create more and better fractures, it could possibly increase the number of locations per square mile. This would reduce the chances of communication between wells. With fractures closer to the well bore, it is easier to get the water and proppant pushed deeper into the source rock. In essence, we will see more pressure from the pump trucks exerted over a shorter distance. This would increase the fractures per square foot. In response, more proppant and water would be needed per foot. Tighter stages would be beneficial as this would produce additional fracturing."
