ABSTRACT:
An improved technique for monitoring subterranean formation test data is provided utilizing an electric wireline to transmit data in real time from sensors positioned downhole in a test string to surface computing and readout equipment. The electrical connection between the downhole sensor and the wireline is made by a current coupler technique which reliably allows for transmission of signals representative of downhole test parameters, with the transmitted signals being insensitive to the presence or conductivity of the well fluids. A transmitter/receiver coupler half is carried in the well via conductor wireline on a latch tool for coupled electrical engagement with a mating receiver/transmitter coupler half contained in a downhole landing receptacle. The latch tool may be electrically activated to mechanically latch and electronically or mechanically activated to unlatch from the landing receptacle, so that a full bore passage is provided through the landing receptacle when the latch tool is not interconnected with the landing receptacle. Two-way data transmission is possible, so that downhole instrumentation and equipment can be activated from the surface via control signals transmitted through the coupler device, and data from downhole sensors can be transmitted in real time to surface computing and recording equipment.
