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 CASTLE 0780 8-17H20 well and the eight additional wells on the Gregory Pad. Gondola will install one JT Unit on the pad and one Arrow 90T genset for each well on the 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. In addition, Gondola will engage an established third party to utilize and route remaining field gas from the Gregory Pad to power a mobile data center and energy intensive computing facilities located on the Big Horn Pad. Gondola anticipates this arrangement to be deployed and operational by year end. |

01/29/2021 | 1) Flaring of natural gas shall comply with COGCC Rule 903.
2) Report metered volumes on Form 7, Operator’s Monthly Report of Operations for gas flared, sold or used on location.
3) The operator is required to obtain and maintain any required air permits from CDPHE.
4) The expectation for permanent flares controlling separators or residual gas will be an enclosed combustion device with a 98% design destruction efficiency for hydrocarbons. Operator shall manage this well so that production volumes do not exceed the combustor capacity.
5) Operator is to provide prior notification to the local emergency dispatch or the local governmental designee of any flaring or venting event.
Operator shall have an approved Gas Capture Plan or have sought and received a variance from the COGCC Commission for continued production without gas infrastructure, prior to January 15, 2022 or wells must be shut in by January 15, 2022.
