Draco OGDP Cumulative Impacts Analysis

Now that the Draco OGDP application has been deemed complete by the ECMC, the documents submitted with the application are available to view/download. Here, we’re taking an opportunity to analyze the submitted Form 2B Cumulative Impacts Data Identification Form and share some new information.

  • Extraction plans to spend 9 weeks constructing the location, 18 weeks to drill the wells, and 23 weeks to complete the wells for Draco, for a total of 50 weeks of pre-production activities, assuming two concurrent electric drilling rigs will be used. The wells will be in production for 20 years.
  • The operator estimates 158,125 diesel vehicle miles will be driven before the wells are put into production to deliver sand, pipe, and other materials to the site.
  • The project will use 3.27 million pounds of proppant/sand during completions activities.
  • They plan to use 12,885,000 barrels of water to frack the 26 wells at Draco, for a total of 541 million gallons of water and an average of 20.8 million gallons per well.
  • They will not be recycling produced water because “the infrastructure necessary to reuse or recycle water does not exist in this area.”
  • Extraction plans to plug and abandon 22 wells at 18 locations, as well as removing 24 oil tanks and 13 produced water tanks.

The following tables were included in the Form 2B materials, showing the various quantities of VOCs and other pollutants that will be emitted by these operations.
