  • Patent number: 8191416
    Abstract: An example instrumented formation tester for injecting fluids and monitoring of fluids described herein includes a downhole tool which can be deployed in a wellbore via a wireline or a drill string. The downhole tool may facilitate the injection of fluids into an underground formation, and the monitoring of the directions in which the injected fluids flow in the formation in an open hole environment. In particular, the downhole tool may be configured for removing the mud cake from a portion of the wellbore wall for facilitating a fluid communication with the formation to be tested.

  • Publication number: 20070175642
    Abstract: The invention generally relates to an apparatus and/or a method for moving an round flexible member into and out of a well bore, and particularly, to an injector with two or more gripping members which bind the outer surface of the round flexible member; two or more actuators which cause the gripping members to bind or release the round flexible member; and at least one reciprocator for translating a gripping member to move the round flexible member, or for repositioning the gripping member. A method of translating a round flexible member is also provided which includes the steps of binding the outer surface of a round flexible member with at least one gripping members by engagement with an actuator, and translating a gripping member by reciprocator to move the round flexible member.

  • Publication number: 20060219406
    Abstract: A system and method is provided for creating a packer in a wellbore for utilization in a variety of wellbore applications. The packer is created by flowing a slurry of particular matter and liquid to a desired location. At the desired location, the slurry is dehydrated, leaving deposition of the particulate matter to create a packer.

  • Publication number: 20050230101
    Abstract: An apparatus for use in a wellbore comprises a housing having a longitudinal axis and a mechanism having one or more impact elements adapted to move along the longitudinal axis in an oscillating manner to impart a back and forth force on the housing to vibrate the housing. In another arrangement, an apparatus for use in a wellbore comprises a housing and at least one impact element rotatably mounted in the housing. The at least one impact element is rotatable to oscillate back and forth to impart a vibration force to the housing.
