  • Patent number: 5749417
    Abstract: A production log which is developed by data recorded in a downhole memory in a well tool as a function of real time and data recorded at the earth's surface as a function of time and merged to produce a log of data as a function of depth. The well tool is moved with a velocity selected to obtain fluid velocity data as a function of time and the velocity of the tool is measured at the earth's surface as a function of time. The functions of time are on a common basis so that a true velocity of fluid flow can be obtained as a function of depth.

  • Patent number: 5554804
    Abstract: A pressure and temperature system for monitoring pressure and temperature conditions in a permanent installation in a high temperature production well traversing earth formations where the system in a pressure tool incorporates a programmable logic array device and a low density memory device. Each of a number of independent pressure tools is programmed to respond to a distinct digital polling signal for selecting a particular tool so that a single wire conductor can be used for data and control signal communication between the pressure tools placed downhole and a computer system situated at the earth surface. The system in a tool is powered up and down for each selected operation to conserve individual component useful life and the number of downhole components subject to high temperature is minimized.

  • Patent number: 5482331
    Abstract: A quick connect coupler for interconnecting pressure sealed housings with pin and socket members where the socket member has a sealing bore and locking grooves. The pin member has a first rotatable ring assembly and a second rotatable ring assembly is mounted on the first ring assembly. A rotatable pawl member in the second ring assembly interlocks the socket member and the ring assemblies against axial and rotational movement. When actuated, the pawl member releases to permit relative rotation to an unlock position where the pawl member is used as a cam member to move the assemblies axially relative to one another to release the sealing connection as well as the locking interconnection.

  • Patent number: 5457988
    Abstract: A system for providing D.C. power at the earth's surface to a downhole well tool in a case hardened side pocket mandrel using an inductive coupling system where the mandrel has a pressure sealed probe member sealingly attached in a side pocket of the mandrel. The probe member extends externally to a cable conductor and is enclosed in a protective housing. A surface located D.C. power source is connected by the cable to a downhole square wave oscillator with a full wave driver to power an inductive coil in the probe member. The end socket of the tool has an inductive coil connected to a full wave rectifier in the tool for providing power to the tool. Pressure sensors in the tool are used to develop frequency shifted key signals to the cable via the inductive coils which provide a digital current modulation and which is detected at the earth's surface.

  • Patent number: 5443124
    Abstract: A stage valve with particular use in cementing a well bore annulus where the stage valve has pressure operated valve member for opening a flow passage in the stage valve and the valve member has differential pressure areas which maintain the valve member open while a fluid moves through the flow passage in one direction and which can be closed by fluid moving in an opposite direction. The flow passage has a choke to develop a pressure differential from the flow of fluid. Spring members can be used with the valve member to close the flow passage when the pressure differential of the fluid flow in one direction is insufficient to maintain the valve member in an open position.
