Patent number: 9416594Abstract: A system and method is provided for drilling a wellbore including a rotary drill bit with a bit body having a plurality of mechanical cutters to cut away formation material as the wellbore is formed; and a directed energy mechanism to direct energy into the formation such that energy from the directed energy mechanism causes fracturing of surrounding material to facilitate drilling in the direction of the directed energy. The energy from the directed energy mechanism is used to enhance the cutting of the mechanical cutters by fracturing surrounding material to facilitate drilling in the direction of the directed energy.Type: GrantFiled: September 25, 2013Date of Patent: August 16, 2016Assignee: Schlumberger Technology CorporationInventors: Benjamin P. Jeffryes, Iain Cooper, Simon H. Bittleston, Geoffrey C. Downton

Publication number: 20140286126Abstract: A method of controlling a streamer positioning device (18) configured to be attached to a marine seismic streamer (12) and towed by seismic survey vessel (10) and having a wing and a wing motor for changing the orientation of the wing. The method includes the steps of: obtaining an estimated velocity of the streamer positioning device, calculating a desired change in the orientation of the wing using the estimated velocity of the streamer positioning device, and actuating the wing motor to produce the desired change in the orientation of the wing. The invention also involves an apparatus for controlling a streamer positioning device including means for obtaining an estimated velocity of the streamer positioning device, means for calculating a desired change in the orientation of the wing using the estimated velocity of the streamer positioning device, and means for actuating the wing motor to produce the desired change in the orientation of the wing.Type: ApplicationFiled: June 3, 2014Publication date: September 25, 2014Inventors: OYVIND HILLESUND, SIMON H.

Patent number: 7822552Abstract: A control device or “bird” for controlling the position of a marine seismic streamer is provided with an elongate, partly flexible body which is designed to be electrically and mechanically connected in series with a streamer. In its preferred form, the bird has two opposed wings which are independently controllable in order to control the streamer's lateral position as well as its depth.Type: GrantFiled: November 7, 2003Date of Patent: October 26, 2010Assignee: WesternGeco L.L.C.Inventor: Simon H. Bittleston

Patent number: 7703517Abstract: Methods and apparatuses for sampling fluid from a subterranean formation penetrated by a wellbore are provided. The subterranean formation has clean formation fluid therein, and the wellbore has a contaminated fluid therein extending into an invaded zone about the wellbore. A shaft is extended from a housing and positioned in a perforation in a sidewall of the wellbore. At least one flowline extends through the shaft and into the housing. The flowline(s) are adapted to receive downhole fluids through the perforation. At least one fluid restrictor, such as a packer, injection fluid or flow inhibitor, may be used to isolate at least a portion of the perforation whereby contaminated fluid is prevented from entering the isolated portion of the perforation. At least one pump selectively draws fluid into the flowline(s).Type: GrantFiled: November 25, 2008Date of Patent: April 27, 2010Assignee: Schlumberger Technology CorporationInventors: Jeffrey A. Tarvin, Julian J. Pop, Simon H. Bittleston, Angus J. Melbourne, Rogerio T. Ramos

Patent number: 5284207Abstract: Once the drilling of an oil or gas well is finished the bore must be cased and cemented. It is important that the cement lining be complete, and to ensure this it is necessary to sweep out the mud in the annulus ahead of the rising cement. Unfortunately, this often proves difficult, and various procedures and mechanisms have been devised in the past to improve the chances of achieving efficient mud-removal and forming a complete cement lining, though none have been truly successful. One of the techniques presently employed involves the utilization of a wash, but it has been noted that such a wash, even when turbulent, has very little component of its movement in the annulus in a direction other than up along the annulus, and that as a result it has very little effect on gelled mud deposits, especially those in the small casing/bore inter-distance of a severely eccentric casing.Type: GrantFiled: May 14, 1992Date of Patent: February 8, 1994Assignee: Schlumberger Technology CorporationInventors: Simon H.
