2/5/2013 | Frac Stimulation in the Greater Wattenberg Area
1. At least seven (7) days prior to fracture stimulation, the operator is to notify all adjacent operators of nonoperated wells within 300’ of the wellbore to be fracture stimulated of the anticipated stimulation date and
the recommended Best Management Practice to shut-in all wells within 300’ of the stimulated wellbore
completed in the same formation. If adjacent operators do confirm or respond that they will comply, operator
will notify the Commission via email.
2. The operator will monitor the bradenhead pressure of all wells within 300’ of the well to be fracture
stimulated if adjacent wells are completed in the same zone.
3. Bradenhead pressure gauges are to be installed 24 hours prior to stimulation by operator and adjacent
well operators. The gauges are to read at least once during every 24-hour period until 24-hours after
stimulation is completed. The gauges are to be of the type able to read current pressure and record the
maximum encountered pressure in a 24-hour period. The gauge is to be reset between each 24-hour period.
The pressures are to be recorded and saved. Alternate electronic measurement may be used to record the
prescribed pressures. Data shall be kept for a period of one year.
4. If at any time during stimulation or the 24-hour post-stimulation period, the bradenhead annulus pressure
of the treatment well or offset wells increases more than 200 psig, as per Rule 341, the operator of the well
being stimulated shall verbally notify each other and the Director as soon as practicable, but no later than
twenty-four (24) hours following the incident. Within fifteen (15) days after the occurrence, the operator and
adjacent operator shall submit a Sundry Notice, Form 4, giving all details, including corrective actions taken. |

2/5/2013 | Storm water management Plans (SWMP) will be in place to address construction, drilling and operations associated with Oil and Gas development throughout the state of Colorado in accordance with Colorado Department of Public Health (CDPHE). BMP’s will be constructed around the perimeter of the site prior to or at the beginning of construction; BMP’s used will vary according to the location, and will remain in place until the pad reaches final reclamation.
Spill Prevention Control and Counter Measures (SPCC) plans will be in place to address any possible spills associated with Oil and Gas operations throughout the state of Colorado in accordance with CFR 112. In accordance with COGCC Rule 1002.f.(2)A. & B., shall provide a designated storage area for dry bulk chemicals and miscellaneous fluids. The storage area shall be covered to prevent contact of precipitation with chemicals, shall be elevated above storm- or standing water, and shall provide sufficient containment to prevent release of spilled fluids or chemicals from impacting soil, surface water or groundwater and will prevent the co-mingling of spilled fluids or chemicals with other E & P Waste.
Housekeeping will consist of neat and orderly storage of materials and fluids. 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 storm water 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 will consist of patrolling the roadways, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of properly and promptly.

2/5/2013 | Great Western – Anti-collision Best Management Practice
Prior to drilling operations, Operator will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottomhole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. For the proposed well, upon conclusion of drilling operations, an as-constructed gyro survey will be submitted to COGCC with the Form 5. |
