APPARATUS AND METHOD FOR COMMUNICATING DATA BETWEEN A WELL AND THE SURFACE USING PRESSURE PULSES

摘要

In one aspect, wellbore apparatus is disclosed that includes a conduit that contains a non-circulating liquid therein and is configured to be placed in a well, and a transmitter that is configured to transmit pressure pulses through the liquid in the conduit. In another aspect, a method is disclosed that includes placing a conduit in the wellbore that is closed at one end and contains a liquid medium therein, and transmitting information in the form of pressure pulses through the liquid medium in the conduit.
