  • Patent number: 9752431
    Abstract: In one aspect, a method of obtaining a fluid from a formation is disclosed that in one embodiment may include: pumping fluid received by a first probe from the formation into the wellbore; pumping fluid received by a second probe from the formation into the wellbore; determining when the fluid received by one of the first and second probes is clean; and pumping the fluid received by the first probe into a sample chamber while collecting the formation fluid received by the second probe from the formation into a storage chamber having an internal pressure less than the pressure of the formation.
    Type: Grant
    Filed: January 11, 2013
    Date of Patent: September 5, 2017

  • Patent number: 7258167
    Abstract: A method and apparatus store energy in an energy storage medium located in an energy storage chamber. As a sampling tool descends into the borehole, the energy storage medium is pressurized with hydrostatic pressure. A sample is collected in a sample chamber by pumping formation fluid into the sample chamber against hydrostatic pressure. The energy storage medium applies the energy stored in the energy storage medium to the sample through a pressure communication member. A pressure multiplier member increases the pressure applied on the sample by the energy storage medium through the pressure communication member to keep pressure on the sample. A biasing water pressure is applied to the sample at the surface so that the energy storage chamber can be removed from the sample chamber.

  • Patent number: 5680049
    Abstract: An apparatus for measuring the resistivity of earth formations penetrated by a wellbore having a conductive conduit. The apparatus includes an elongated sonde mandrel, a plurality of electrodes positioned at axially spaced apart locations along the mandrel, the electrodes being electrically insulated from the mandrel and from each other, the electrodes adapted to electrically contact the conduit and positioned collinearly so that the electrodes contact the conduit when the mandrel is radially displaced towards the wall of the conduit. Some electrodes are for injecting electrical current into the conduit, other electrodes are for measuring voltage drop along the conduit at axially spaced apart locations. The mandrel includes selectively extensible locking arms for urging the mandrel into contact with the conduit. The arms are radially positioned opposite to the electrodes.
