DOWNHOLE MEASUREMENT APPARATUS

摘要

A downhole measurement apparatus (10) comprises a downhole flow control device (22) comprising a tubular body having an internal flow path and at least one fluid port (24) for permitting flow of a fluid between the internal flow path and an external location. The apparatus further comprises a sensor assembly (26) comprising a tubular body and a sensor arrangement (28) configured for use in determining a fluid pressure externally of the flow control device (22) and a fluid pressure within the internal flow path of the flow control device (22).
