A comparison study was done in the Marcellus to measure production of wells completed with StackFRAC systems compared to surrounding offset wells in the field completed using the CCPP method. The two study areas were in Washington County, PA and Susquehanna County, PA and cumulative production was compared at 6, 12 and 24 months. In both areas the StackFRAC wells were drilled and completed between 2007 and 2009, while the CCPP wells included those completed in the same time period to newer wells completed in 2011. The StackFRAC wells were completed with an average of 8 stages in both counties and an average lateral length of 2,500 ft and 1,800 ft in Washington and Susquehanna County, respectively.
In both study areas, the wells completed with StackFRAC systems outperformed the CCPP completed wells in terms of production. The StackFRAC wells produced from 43% to 84% higher than the offset CCPP average in Washington County (Figure 1). These results were also seen in Susquehanna County with the StackFRAC wells increasing production by up to 37% compared to the offset CCPP average. In addition to higher production as demonstrated by this study, StackFRAC systems also provide improved efficiency and cost savings compared to the CCPP method. StackFRAC completed wells can be stimulated in less than a day compared to approximately 2 to 3 days required for CCPP wells. This efficiency also reduces equipment and personnel costs.
With the ongoing success of the StackFRAC system throughout the U.S., Packers Plus is focused on developing technology that will continue to improve production results for operators. For example, the QuickFRAC® system is allowing operators to increase stage numbers available in the StackFRAC HD system. Packers Plus has run multiple jobs with this new technology, achieving over 40 stages in a single well. With this and other technologies being developed by Packers Plus, operators can continue to achieve improved results moving forward in the Marcellus Shale.
