Publication number: 20170145760Abstract: A method for conveying an interventional tool downhole in a substantially self-piloting fashion. The method includes moving the tool in the well while using a communicative conveyance line coupled to a winch at the oilfield surface. Thus, real-time readings regarding downhole tool speed, line tension, etc. may be analyzed at surface and utilized to adjust the moving of the tool in an ongoing feedback loop. As a result, the adjustments are made based on true circumstances downhole as opposed to surface-based readings which may otherwise be less accurate. Therefore, efficiency of the operations may be maximized, operator time freed and the likelihood of catastrophic line based failures reduced.Type: ApplicationFiled: June 27, 2014Publication date: May 25, 2017Inventors: Jean-Pierre Poyet, Todor K.

Publication number: 20160237812Abstract: A system for delivering a fiber optic slickline through a deviated well with a battery powered tractor. The system includes a tractor having an efficiency rating of at least about 30% so as to adequately serve as a conveyance aid without the requirement of surface supplied power. For example, regulating of drive sections of the tractor may take place through a hydraulic section. Thus, arms of the tractor may be hydraulically locked in an open position without the requirement of continuous power to maintain the arms in an open position. At the same time, however, the hydraulic section may include accumulator capacity so as to allow for temporary responsive collapse of the arms for sake of navigating a restriction in the well.Type: ApplicationFiled: September 30, 2013Publication date: August 18, 2016Inventors: Pierre-Arnaud Foucher, Matthew Billingham, Todor K.

Patent number: 9376887Abstract: This stuffing box (46) defines a circulation passage (66) of a cable working line (28), a packer (70), and a back-pressure resistant valve (74). The passage (66) extends between an upstream end (62) of the stuffing box (46), intended to be connected to a well, and a downstream end (64). The back-pressure resistant valve (74) is arranged in the passage (66) to prevent, in case of break of the line (28), the back-pressure of a fluid from the upstream end (62) towards the downstream end (64). The or each packer (70) is situated between the upstream end (62) of the stuffing box (46) and the back-pressure resistant valve (74). No packer (70) is arranged between the back-pressure resistant valve (74) and the downstream end (64).Type: GrantFiled: April 26, 2011Date of Patent: June 28, 2016Assignee: GEOSERVICES EQUIPMENTSInventors: Yvon Bernard, Pierre-Arnaud Foucher, Francois Girardi

Patent number: 9260956Abstract: A system is provided that is conducive to multi-stage stimulation in a near-continuous fashion. That is, unlike conventional stimulation systems, embodiments herein may operate without the requirement of traditional plug-setting, perforating and fracturing interventions on a zone by zone basis for a cemented completion. Rather, the system is outfitted with frac sleeves that may be shifted open to expose the bore to the formation while simultaneously achieving a seal through a ball drop technique. Once more, this manner of operation is rendered practical by the sleeve being of a passable configuration such that cementing of the casing is not impeded.Type: GrantFiled: June 3, 2013Date of Patent: February 16, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Wade D.
