Publication number: 20140262251Abstract: Fractures are induced from lobe shaped inflatable members disposed at different axial locations along a string with frac ports in the circumferential gaps between the lobes. The lobes are inflated by landing a ball on a seat on a sleeve that is initially shifted enough to expose a fill port on each lobe. The lobes are inflated to a pressure that initiates fractures in the formation as the lobes extend. Further raising the pressure induces the sleeve to move a second time to open frac ports. The annulus can be cemented and fracturing can penetrate the cement to further propagate the initiated fractures from lobe inflation. The process is repeated at different levels until the zone of interest is completed. Sensors can relay information by telemetry techniques as to the onset of fractures or other well conditions. The sleeve for the frac ports can be moved in a variety of ways without intervention tools.Type: ApplicationFiled: March 13, 2013Publication date: September 18, 2014Applicant: BAKER HUGHES INCORPORATEDInventor: BAKER HUGHES INCORPORATED

Publication number: 20140014334Abstract: A positional feedback system includes a seal assembly coupled to a running tool, the seal assembly having a seal ring and an energizing ring positioned between a hanger and a subsea wellhead. The energizing ring moves relative to the seal ring from an unset position to a set position to seal to the wellhead and the hanger. The system includes a magnet disposed on the energizing ring and having a magnetic field. One or more sensing devices are disposed on running tool and positioned in the magnetic field of the magnet in the set position and the unset position. The sensing devices are configured to communicate with a surface platform when the rare earth magnet passes a magnetic field through the sensing devices.Type: ApplicationFiled: July 13, 2012Publication date: January 16, 2014Applicant: Vetco Gray U.K. LimitedInventors: Guy Harvey Mason, Stephen Paul Fenton

Patent number: 8616288Abstract: A plunger lift system of an oil or gas well and method of use is described. The plunger lift system includes a plunger, a sensor, a flow valve assembly, and a controller. The plunger is positioned within the tube string and travels up and down the string in response to the opening and/or closing of the flow valve assembly. The sensor is connected to the tube string and detects vibrations generated by impacts created by the plunger temporarily catching on gaps in the tube string. The sensor generates a sensor signal in response to the impacts of the plunger which are used by the controller to determine the velocity of the plunger within the tube string. If the velocity of the plunger exceeds a preselected maximum velocity, the controller selectively opens or closes the flow valve assembly to reduce the velocity of the plunger.Type: GrantFiled: December 10, 2010Date of Patent: December 31, 2013Inventors: Paul Byrne, Phillip P. Harris
