Inventories

Inventories consisted of the following at December 31:

(In thousands)	2022		2021
Raw materials:
Fluids Systems	$	110,623	$	119,242
Industrial Solutions	3,966		4,939
Total raw materials	114,589		124,181
Blended fluids systems components	29,244		27,793
Finished goods — mats	5,738		3,367
Total inventories	$	149,571	$	155,341

Raw materials for the Fluids Systems segment consist primarily of chemicals and other additives that are consumed in the production of our fluids systems. Raw materials for the Industrial Solutions segment consist primarily of resins, chemicals, and other materials used to manufacture composite mats, as well as materials that are consumed in providing ground protection and other services to our customers. Our blended fluids systems components consist of base fluids systems that have been either mixed internally at our blending facilities or purchased from third-party vendors. These base fluids systems require raw materials to be added, as needed to meet specified customer requirements.

The decrease in inventories in 2022 was primarily attributable to a $36.6 million decrease related to our divestitures described in Note 2, including the impact of related inventory impairments, partially offset by activity-driven increases and raw materials cost inflation in the Fluids Systems segment.

The Fluids Systems segment operating results for 2022 includes $8.0 million of total charges for inventory write-downs included in impairments and other charges, primarily attributable to the reduction in carrying values of certain inventory related to the exit of our Gulf of Mexico operations to their net realizable value.
