Receivables [Abstract]  
Accounts Receivable and Allowance for Credit Losses Accounts Receivable and Allowance for Credit Losses
We extend credit to customers in the normal course of business. Our customers are predominantly oil and gas exploration and production companies located in the U.S. and the Middle East. Our receivables are short-term in nature and typically due in 30 to 60 days after the billing for the product that has been delivered or the services that have been provided to the customer. We typically do not accrue interest on delinquent receivables. Accounts receivable includes both amounts billed and currently due from customers, as well as unbilled amounts resulting from accrued revenue associated with products delivered and services performed for which billings have not yet been submitted to the customers. Total unbilled revenue included in accounts receivable as of March 31, 2026 and December 31, 2025 was $170.8 million and $39.4 million, respectively.

We maintain an allowance for credit losses to provide for the amount of billed receivables we believe to be at risk of loss. In our determination of the allowance for credit losses, we pool receivables with similar risk characteristics based on customer size, credit ratings, payment history, bankruptcy status and other factors known to us, and then apply an expected credit loss percentage. The expected credit loss percentage is determined using historical loss data adjusted for current conditions and forecasts of future economic conditions. Accounts deemed uncollectible are applied against the allowance for credit losses. The following is a roll-forward of our allowance for credit losses.
