ASSET RETIREMENT OBLIGATIONS

ASSET RETIREMENT OBLIGATIONS

In connection with our well servicing activities, we operate a number of saltwater disposal (“SWD”) facilities. Our operations involve the transportation, handling and disposal of fluids in our SWD facilities that are by-products of the drilling process. SWD facilities used in connection with our fluid hauling operations are subject to future costs associated with the retirement of these properties. As a result, we have incurred costs associated with the proper storage and disposal of these materials.

Annual accretion of the assets associated with the asset retirement obligations were $0.2 million, less than $0.1 million and $0.6 million for the year ended December 31, 2017, for the periods from December 16, 2016 through December 31, 2016 and from January 1, 2016 through December 15, 2016 and for the year ended December 31, 2015, respectively. The application of fresh-start accounting with the effectiveness of the Company's Plan of Reorganization has resulted in the financial statements of the Predecessor and Successor not being comparable. A summary of changes in our asset retirement obligations is as follows (in thousands):
