Cairn Energy PLC is an independent oil and gas exploration and development company. The company engages in exploration activities in Greenland, Europe, and western Africa. Cairn gains access to potential fields through government-issued licenses and uses survey techniques to identify hydrocarbon reservoirs offshore. Exploration and appraisal drilling is used to determine if prospects exist, and to establish field size and appropriate production methods. Cairn counts on different drilling and well stimulation techniques to maintain peak production levels in its assets. Production can be exported directly from offshore facilities or connected to a nearshore or onshore facility for processing and export.
