Based on the successes of Extreme Limited Entry (XLE) in other basins, Great Western Petroleum (GWP) performed an experiment to test XLE in the first zipper group of a two-zipper group pad. The goal was to find a design that would yield the same production, but with less cost. Based on the results from zipper one, the best design could then be implemented on the same pad in the second zipper group. This allowed for a direct comparison of hydraulic fracturing designs, minimizing geologic impact. The primary focus in this study involved Distributed Acoustic Sensing (DAS) using wellbore fiber optic cable. An opportunity was seen to test the data quality of the latest deployment methods, specifically a pump-down single-use fiber optic cable. This DAS acquisition also provided offset strain and microseismic data in the first and second zipper groups. High level observations resulting from this project include: 1) The data quality associated with the single-use fiber looked comparable to the other fiber optic deployment methods; 2) The Uniformity Index was high for most designs; 3) Results from the offset strain and microseismic analysis from tighter and more clusters per stage showed less interference than with legacy designs; and 3) RTA showed that the production was better with the new hydraulic fracture design.
