Patent number: 9891153Abstract: A system is described for evaluating coagulation of particles in a downhole fluid-particle mixture based on dielectric measurements. An example downhole treatment is one in which flocs are used to plug a high-permeability subterranean formation zone as part of a stimulation procedure. An injection tube is positioned within the wellbore to the high-permeability zone. An instrumented section of tubing includes one or more dielectric probes that are positioned and configured to make dielectric measurements of the particle-fluid mixture flowing in the tubing or in the annulus. The downhole dielectric measurements are used to indicate whether or not the particle-fluid mixture has the desired structural properties. An operator on the surface can make adjustments in real-time according to the received dielectric measurements.Type: GrantFiled: September 19, 2013Date of Patent: February 13, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Mustapha Abbad, Khaled Hadj-Sassi, Stephen Dyer

Publication number: 20160201440Abstract: Improved notching techniques are described for transverse fracture initiation from the wellbore (cased or open).

Publication number: 20150322760Abstract: Systems and methods are described for controlling the location where a fracture initiates and the fracture direction at the initiation point. A mechanical device is positioned in a main wellbore or partially or fully in a side hole off of the main wellbore. The mechanical device is actuated so as to contact the formation walls and induce stress in the formation. According to some embodiments, fractures are also initiated using the mechanical device. A hydraulic fracturing process is then carried out to fracture and/or propagate fractures in locations and/or directions according to the actuation of the mechanical device.Type: ApplicationFiled: October 11, 2013Publication date: November 12, 2015Inventors: Mohammed Badri, Stephen Dyer, Reza Taherian

Publication number: 20150308224Abstract: Systems and methods using enhanced flow control devices are described. The flow control devices can be selectively closed completely or have its effective flow area reduced to restrict production (or injection) by use of a chemical trigger mechanism. In addition, some of the systems described herein deploy specific targeted chemical tracers, dissolvable in the unwanted production fluid (e.g. water or gas). These chemical tracers once dissolved will enter the production stream and be identified at the surface. The identification will determine which segment of the completion is producing the unwanted fluid. According to some embodiments, an appropriate chemical trigger is placed, for example, by pumping down through the tubing and utilizing intelligent completion valve to place the chemical, or by spotting with coiled tubing and bullhead to the formation, or by other methods of chemical placement. The chemical trigger will only trigger the active chemical in the appropriate flow control device.Type: ApplicationFiled: July 7, 2015Publication date: October 29, 2015Inventors: Stephen Dyer, Athar Ali, Frank F.
