Abstract: An apparatus for protecting a wireline at a top of a well from wear due to flow of fluid about the wireline includes a valve assembly coupled to a wellhead for introducing fluid into a well. A wireline adaptor section passes the wireline from outside the well and adaptor section into the well through the wellhead. The wireline adaptor section includes a hollow rigid tube passing from the wireline adaptor section into a flow passage for the fluid and has an end extending away from the adaptor section. A flexible bushing is coupled to an extends beyond the end of the tube in a direction toward the wellhead. A wireline is slidable from the outside of the adaptor section the tube and bushing and out the end of the tube.

Abstract: A method and means is provided for receiving and passing data up hole to the top (22) of a well bore (20a) while passing fracturing fluid (54,60) down hole to a geological formation (44) at a zone (29) in the well bore. A flexible line (36) has suspended thereform, a receiver (34) for receiving data signals from a separate sensor (30) and transmitter (28), and a stiffener (32). The stiffener is positioned up the well bore from a lower extremity (29b) of the receiver. The flexible line is adapted for passing data signals representing a parameter represented by the received data signals up to the top (22) of the well bore.

Abstract: Method and an arrangement are disclosed for recovery of data signals representing a parameter from down hole to the top of a well bore (20a). The well bore has conductive fluid (54,60) and the data signals represent a parameter down hole in the well bore. An exposed electrode receiver (34 ) is lowered in the well bore suspended from a flexible line (36) while the line extends to the top of the well bore. Electrical potentials representing the parameters are received by the receiver from the conductive fluid. Data signals representing the parameter represented by the received potentials are passed over the flexible line to the top of the well bore.

Abstract: Method and apparatus are disclosed for recovery of data in an oil or gas well having a well bore (20a) for passing fluid (54), transversely across a side (29a-29b) of the well bore, at a down hole location (29a-29b ) of the well bore and longitudinally in the well bore, between a geological formation (44) located at the down hole location and a top portion (22) of the well bore. A sensor (30) senses, substantially at the down hole location, a parameter of the fluid. A transmitter (28) transmits into the well bore, data signals which represent the sensed parameter. A receiver (34) and a flexible line (36) are lowered in the well bore separate from the sensor and transmitter, while the receiver is suspended from the flexible line. The data signals from the transmitter are received with the receiver. Data signals, which represent the parameter, which is represented by the received data signals, are passed over the flexible line to the top portion of the well bore.
