Disaggregation of revenue

 

We disaggregate our revenue from contracts with customers by geography, as disclosed in Note 5 above, as we believe this best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Additionally, we disaggregate our revenue into areas of capability.

 

The following table sets forth the total amount of revenue by areas of capability as follows (in thousands):

 

  

Year Ended December 31,

 
  

2021

2019

 

Well construction

 $112,126  $-  $- 

Well management

  713,636   675,026   810,064 

Total

 $825,762  $675,026  $810,064 

 

Contract balances

 

We perform our obligations under contracts with our customers by transferring services and products in exchange for consideration. The timing of our performance often differs from the timing of our customers’ payments, which results in the recognition of receivables and deferred revenue.

 

Unbilled receivables are initially recognized for revenue earned on completion of the performance obligation which are not yet invoiced to the customer. The amounts recognized as unbilled receivables are reclassified to accounts receivable upon billing. Deferred revenue represents the Company’s obligations to transfer goods or services to customers for which the Company has received consideration, in full or part, from the customer.

 

Contract balances consisted of the following as of December 31, 2021 and  December 31, 2020 (in thousands):

 

  

December 31,

Accounts receivable, net

 $236,158  $159,421 

Unbilled receivable

 $94,659  $45,500 

Deferred revenue

 $17,038  $29,063 

 

The Company recognized revenue of $15.4 million, $6.3 million and $8.9 million for the years ended December 31, 2021, 2020 and 2019, respectively, out of the deferred revenue balance as of the beginning of the applicable year. As of December 31, 2021, $15.7 million of our deferred revenue was classified as current and is included in “Other current liabilities” on the consolidated balance sheets, with the remainder classified as non-current and included in “Other non-current liabilities” on the consolidated balance sheets.

 

Transaction price allocated to remaining performance obligations

 

Remaining performance obligations represent firm contracts for which work has not been performed and future revenue recognition is expected. We have elected the practical expedient permitting the exclusion of disclosing remaining performance obligations for contracts that have an original expected duration of one year or less and for our long-term contracts we have a right to consideration from customers in an amount that corresponds directly with the value to the customer of the performance completed to date.
