SEGMENT REPORTING

We operate our business in three reportable segments:  (1) Reservoir Description, (2) Production Enhancement and (3) Reservoir Management.  These business segments provide different services and utilize different technologies.

• Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.

• Production Enhancement: Includes products and services relating to reservoir well completions, perforations, stimulations and production. We provide integrated services to evaluate the effectiveness of well completions and to develop solutions aimed at increasing the effectiveness of enhanced oil recovery projects.

• Reservoir Management: Combines and integrates information from reservoir description and production enhancement services to increase production and improve recovery of oil and gas from our clients' reservoirs.

Results for these business segments are presented below.  We use the same accounting policies to prepare our business segment results as are used to prepare our Consolidated Financial Statements.  We evaluate performance based on income or loss before income tax, interest and other non-operating income (expense). All interest and other non-operating income (expense) is attributable to the Corporate & Other area and is not allocated to specific business segments. Summarized financial information concerning our segments is shown in the following table (in thousands):
