Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at offsite, suitable facilities. If spills occur prompt cleanup is required to minimize any commingling of waste materials with stormwater runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks. Any waste product from maintenance will be containerized and transported offsite for disposal or recycling. There will be no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the roadway, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of properly. false 1d9c4ac5-78d5-466e-bcb4-74639a500261 401811307 4 Drilling/Completion Operations Bradenhead Monitoring: Noble Energy acknowledges and will comply with COGCC Policy for Braden-head Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012. false 999f8668-754e-4b0f-95e2-814caed5059b 401811307 2 Storm Water/Erosion Control If a skid is performed for the subject well, then the only required BOPE tests are for the BOPE connection bonnet seal breaks, as long as a full BOPE test was performed at the beginning of the pad, and as long as all necessary BOPE tests are completed at least every 30 days during the pad operations. false d9fab306-df12-41bf-abe0-ed8923f83cff 401811307 3 Drilling/Completion Operations One of the first wells drilled on the pad will be logged with open-hole resistivity log with gamma-ray, from the kick-off point into the surface casing. All wells on the pad will have a cement bond log (CBL) with gamma-ray run on production casing (or on intermediate casing if production liner is run) into the surface casing. The horizontal portion of every well will be logged with a measured-while-drilling gamma-ray log. The Form 5, Completion Report, for each well on the pad will list all logs run and have those logs attached.The Form 5 for a well without open-hole logs shall clearly state “No open-hole logs were run” and shall clearly identify the type of log and the well (by API#) in which open-hole logs were run. false 1c5530b7-5be5-4849-9ea6-defd6db306a4 401811307 5 Drilling/Completion Operations Noble Energy will perform an anti-collision evaluation of all active (producing, shut in, or temporarily abandoned) offset wellbores that have the potential of being within 150 feet of a proposed well prior to drilling operations for the proposed well. Notice shall be given to all offset operators prior to drilling. false 401811307 1ST 8 1 2 5 1 2 17 17720 1980 17720 0 PLANNED 401811307 CONDUCTOR 26 16 42 80 144 80 0 0 PLANNED 401811307 SURF 13 3 4 9 5 8 36 1850 658 1850 0 0 PLANNED 401811307 NIOBRARA NBRR 640 GWA Thread was being aborted.
