Core Handling and Evaluation
Cores are taken in order to measure accurately the reservoir parameters in hydrocarbon and water bearing formations, and for geological purposes. Whether a conventional steel/aluminium inner barrel coring or fibreglass inner barrel coring technique will be used for a particular well is specified in the drilling or test programme and is based on the expected formation conditions. In certain circumstances it may be necessary to change the technique, e.g. a pay zone may be found to be much more viable than expected.
