Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Intangible Assets | Goodwill and Intangible Assets The Company’s amortizable intangible assets relate to third-party customer contracts, which were $15.0 million at December 31, 2020 (Successor). Accumulated amortization of intangible assets was immaterial at December 31, 2020 (Successor). The Company’s non-amortizable intangible assets at December 31, 2020 (Successor) were $28.7 million, consisting of the Company’s interest in OMP GP and seismic data. In addition, the excess of the Successor’s reorganization value over the fair value of identified tangible and intangible assets as of the Emergence Date was reported separately on the Company’s Consolidated Balance Sheets as goodwill. The Company’s non-amortizable intangible assets at December 31, 2019 (Predecessor) were $0.7 million, consisting of seismic data. Based on the carrying value of amortizable intangible assets at December 31, 2020 (Successor), amortization expense for the subsequent five years is estimated as follows:

2021 | $ | 2,723 |

2023 | 2,723 |
2024 | 2,723 |
