03/16/2016 | A closed loop system must be implemented during drilling (as indicated on the Form 2 and Form 2A). All cuttings generated during drilling with oil based mud (OBM) must be segregated from water/bentonite based mud-(WBM-) generated drill cuttings and placed separately on the well pad. All OBM-generated drill cuttings must be kept in tanks/containers, or placed on a lined/bermed portion of the well pad; prior to disposition. The moisture content of any OBM-generated drill cuttings in a tank, cuttings containment area, or pile shall be as low as practicable to prevent accumulation of liquids greater than de minimis amounts. The operator has indicated that ‘Cuttings Disposal’ will be “OFFSITE” and that the ‘Cuttings Disposal Method’ will be “COMMERCIAL DISPOSAL” (as shown in the ‘DRILLING WASTE MANAGEMENT PROGRAM SECTION’ of the Form 2A#400958033; OGCC ID#414127). All liners associated with oil-based drilling mud and OBM-generated drill cuttings must be disposed of offsite per CDPHE rules and regulations.
Any changes to drill cuttings management and disposal at this location will require submittal (via a Form 4 Sundry Notice) and approval of a Waste Management Plan detailing the changes (specifying cuttings characterization methods, cuttings management, amendment, and onsite disposal location[s]). At the time of closure, if the drill cuttings (either OBM- or WBM-generated) are to be left onsite (cuttings management area, the cut portion of the pad, cuttings trench, dry cuttings drilling pit, beneficial reuse during reclamation), they must also meet the applicable standards of Table 910-1. Although “landfarming” of E&P waste is prohibited on the location; this shall not preclude onsite disposal of E&P waste in accordance with COGCC Rules and permit conditions. Any material which does not meet Table 910-1 criteria will either be manifested and disposed offsite at an approved commercial facility, or amended further onsite to comply with Table 910-1.
If operator determines that long-term onsite management of OBM-generated drill cuttings is necessary, an approved Form 27 remediation plan and an approved Form 4 Sundry Notice requesting a reclamation variance, will be required. |

01/27/2021 | Following the anticipated acquisition of certain assets owned and operated by SandRidge Energy in Jackson County, Colorado, SandRidge acknowledges Gondola Resources plans to modify SandRidge’s pending Gas Capture Plan for the Hebron 0780 4-7H well and the six additional wells on the Mutual Pad. Gondola will install one natural gas-powered CAT driven 400 KW generator at the Mutual Pad and use natural gas from the wells to power the engines on the pad. This work is expected to commence in the Spring of 2021 and conclude in the Summer of 2021. Remaining gas volumes will be routed to the Big Horn Pad where Gondola will be installing a mobile data center and energy intensive computing facilities located on the Bighorn Pad. Gondola anticipates this arrangement to be deployed and operational by year end. |
