Core Laboratories (CLB)

The company reports through two main businesses: Reservoir Description and Production Enhancement. Reservoir Description provides laboratory analysis, field services, and interpretation of core samples, reservoir fluids, and related geological data. These services help customers assess reservoir quality, estimate reserves, model production potential, and determine how crude oil and natural gas can be recovered and processed more efficiently. This segment is typically the company’s largest source of revenue.

Production Enhancement supplies technologies and services used to increase output from existing and newly completed wells. Its offerings include diagnostic tools, completion products, and systems that support perforating, stimulation, and reservoir monitoring. Core Laboratories also manufactures specialised equipment used in its laboratory and field-service activities, giving it a proprietary product base alongside its consulting and analytical work.

The company serves oil and gas producers around the world and is closely tied to upstream spending, reservoir development activity, and the industry’s focus on extracting more value from existing assets. Its competitive position rests on patented technologies, long-standing customer relationships, and technical expertise in reservoir evaluation rather than on large-scale drilling or commodity production.
