Raw materials for the Fluids Systems segment consist primarily of barite, 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 spill containment 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 increase in inventories in the first quarter of 2022 was primarily attributable to a combination of activity-driven increases, purchases supporting the start-up of new international contracts in the Fluids Systems segment, the production of mats in the Industrial Solutions segment for anticipated sales in the second quarter of 2022, as well as raw material cost inflation.
