Paper Number: SPE-180217-MS
... Abstract The Denver-Julesburg (DJ) Basin has seen oil and gas production for more than a century. It is going through a new cycle of development with horizontal drilling and high-intensity hydraulic fracturing. Since the first horizontal wells in 2008 nearly 4,000 Niobrara and Codell...

Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180215-MS
... Abstract Hydraulic fracturing operations require large amount of water which, in some cases, could reach six million gallons per treatment. Fresh water, from surface and subsurface sources, is usually used to formulate the fracturing fluid. The use of produced water in hydraulic fracturing has...

... can create localized "pressure sinks." When a nearby infill well is fractured, the hydraulic fracture grows towards areas of lowest stress (the depleted area), which can damage the parent well. Subsequently, the production potential of the new well is decreased because it is now draining from the same...

... of hydraulic fracture and multi-stages fracturing can mitigate the negative effects on the formation of condensate bank, but the effects cannot be completely removed. A huff-n-puff methane injection has been proven to be an effective method to reduce the effect of condensate by maintaining the reservoir...

.... In this study, we use both methods to history match the production of hydraulically fractured unconventional wells, followed by forecasting future production to establish a well's EUR (Estimated Ultimate Recovery) for reserves determination purposes. This study's goal is to quantify the differences one might...

... injection rate and light-weight proppant are beneficial in transporting proppant through fracture junctions to reach further in both hydraulic fractures and natural fractures. Proppant transport models developed in this work fully incorporate the interaction between proppant particles and carrying fluid...

... Abstract Surfactants are one of the essential additives included in hydraulic fracturing fluids to decrease interfacial tension to improve flow back to the surface for better well productivity. The surfactant can be adsorbed on the formation surface, changing reservoir wettability, which can...
