Cabot announces 10-well pad in the Marcellus

Cabot Oil & Gas Corporation is pleased to announce the results and details of a 10-well pad located in Susquehanna County, Pennsylvania. This is the first of Cabot’s locations in the Marcellus to have 10 wells drilled from one location and is setting a new standard for operational efficiencies and technological advancement.

With the efficiencies gained during the drilling and completions processes, approximately $6 million was saved in total costs of developing the site. With these savings, the natural gas that is coming from the 10-well pad location is being produced for a lower overall cost to Cabot compared to other wells.

This location is also the first Cabot location to have been hydraulically fractured by an entirely bi-fuel truck fleet. The engines of the Baker Hughes fleet were powered by dual-fuel engines via line gas from nearby producing Cabot wells. The natural gas used amounted to 15.1 Mmcf for the entire pad site and displaced approximately 110,000 gallons of diesel during the operations. This project demonstrated that not only is the use of bi-fuel technology during the hydraulic fracturing process on larger scale well pad is possible, it is also economical and provides added benefits to the environment.

The ten wells have started producing and the initial numbers show a strong production rate from all of the wells. The pad showed an initial production rate (IP) of 201 Mmcf per day and a 30-day production rate of 168 Mmcf per day. The IP and 30-day rates per 1,000 ft. of lateral exceeded Cabot’s 14 Bcf type curve – further demonstrating the consistency of results across the Marcellus acreage.


The decreased usage of diesel during hydraulic fracturing has several environmental benefits due to the use of natural gas. Independent third party testing has shown that the substitution of diesel provides a 50% reduction in nitrogen oxides (NOx), a 70% reduction in particulate matter (PM), and effectively brings the level of carbon monoxide down to 0%.

In addition to the environmental benefits, Cabot also realized a cost savings due to the lower cost of natural gas. Throughout the hydraulic fracturing process on the Bray, the overall substitution rate of line gas for diesel varied between 50-70% to optimize the power output for the engines.

Several drilling and completions efficiencies contributed to the overall cost savings on the Bray pad location:

  • Location and road construction
  • Rig mobilization
  • Frac mobilization
  • Zipper frac operations
  • Water resources
  • Utilization of line gas
