Publication number: 20090314499Abstract: A multi-string well has an electric submersible pump (ESP) that can be removed without killing the well. A slotted liner is sealingly secured externally to casing and internally to a guide string that remains in the wellbore when the ESP is removed. A ported sub is part of the guide string and a concentric screen that can have instruments that moves relatively to the guide string can selectively allow flow in an annulus between them and to the ported sub or that annulus between the guide and concentric strings can be blocked off by manipulation of the concentric string to close the ported sub. With the lower portion of the well now blocked off, the wellhead can be removed so that the ESP can come out with the production string. The device has particular application to steam assisted gravity drainage (SAGD) systems as well as other downhole applications.Type: ApplicationFiled: June 18, 2008Publication date: December 24, 2009Applicant: Baker Hughes IncorporatedInventors: Terry R. Bussear, Kirk J. Huber

Publication number: 20080202748Abstract: A method of producing a well utilizes a submersible pump run on a line, such as braided wire rope, that includes power conductors. The operator sets a packer in the casing, the packer having a check valve and a tieback receptacle. The operator pressure tests the integrity of the casing above the packer, and if it passes, then runs the pump assembly on the line. The pump assembly has a shroud with a downward extending extension that seals to the passage of the packer. If the pressure test of the casing fails, the operator runs a liner into the well and engages the tieback receptacle. A smaller diameter pump is then lowered on a line into the liner and into engagement with the packer.Type: ApplicationFiled: February 28, 2007Publication date: August 28, 2008Inventors: Terry R. Bussear, Grant F. Smith

Patent number: 7104331Abstract: An apparatus and methods are disclosed for using optical sensors to determine the position of a movable flow control element in a well control tool. A housing has a movable element disposed within such that the element movement controls the flow through the tool. An optical sensing system senses the movement of the element. Optical sensors are employed that use Bragg grating reflections, time domain reflectometry, and line scanning techniques to determine the element position. A surface or downhole processor is used to interpret the sensor signals.Type: GrantFiled: November 7, 2002Date of Patent: September 12, 2006Assignee: Baker Hughes IncorporatedInventors: Terry R.

Patent number: 6712141Abstract: A method and apparatus for placing acoustic devices in wellbores. The method comprises: providing a tubing with at least one anchoring device in the wellbore, where the anchoring device is extendable to the wellbore to exert a force on the wellbore; attaching at least one acoustic device to at least one anchoring device; placing the tubing in the least one acoustic device attached to the at least one anchoring device in the wellbore; and setting the anchoring device to extend to the wellbore to exert a force on the wellbore, thereby coupling the acoustic device to the wellbore. The wellbore system comprises a tubing that has an annular space between the tubing and the wellbore. At least one anchoring device is disposed on an outer surface of the tubing and extends to and exerts a force on the wellbore.

Publication number: 20020179364Abstract: A system and method for utilizing a surface located oscillator to generate seismic signals at a downhole location. The system includes a vibratory source for generating axial vibrational energy in a tubular string anchored in the borehole at a suitable location. The vibratory source may be operated at a predetermined frequency or may generate a swept frequency signal. The axial vibrations are transmitted through the tubular string and impart a seismic signal through the anchor to the formation.. In different configurations, the system imparts broadband seismic signals into the formation. Sensors are mounted on the vibratory source and downhole anchor for monitoring the system operation. Seismic receivers are deployed on the surface, in offset wells, or in the source well. Signals from the receivers are transmitted to a control unit. The control unit utilizes the sensor and receiver signals to control the operation of the vibratory source.Type: ApplicationFiled: January 15, 2002Publication date: December 5, 2002Applicant: Baker Hughes IncorporatedInventors: Terry R. Bussear, Michael W. Norris
