DISCONTINUED OPERATIONS

In the first quarter of 2018, in a continuing effort to streamline our business and align our business strategy for further integration of services and products, the Company committed to divest the business of our full range of permanent downhole monitoring systems and related services, which had been part of our Production Enhancement segment. We anticipate the sale of this business line will occur by the end of the first quarter of 2019.
