Patent number: 10968713Abstract: A technique employs the use of oscillations downhole to facilitate a desired functionality of a downhole tool. According to this technique, a tool is initially conveyed downhole and operated to perform a function that relates to a downhole application. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e.g. freeing the tool from a stuck position.Type: GrantFiled: October 12, 2016Date of Patent: April 6, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Edward Harrigan, Jahir Pabon, Satish Kumar, Sashank Vasireddy, Murat Ocalan, Shunfeng Zheng

Patent number: 10119370Abstract: A downhole kinetic energy storage system for wellbore completions is configured for installation downhole for extended periods of time, such as 10 year or more. The kinetic energy storage system receives power from a low power source, which can be due to a “power bottleneck” to the downhole location such as inductive coupling, optical fiber, downhole energy harvesting, and/or subsea wellhead configurations. The system stores the available low-power as rotational energy in a flywheel and then when demanded converts the rotational energy into electrical energy at a temporary power level exceeding the low power source. The temporary high power energy is used for wellbore completion applications such as actuating a flow control or other downhole valve.Type: GrantFiled: June 1, 2015Date of Patent: November 6, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Murat Ocalan

Patent number: 9803462Abstract: Techniques for axial vibration control of wireline tools and cables during logging operations. In undesirable cases the axial vibrations may lead to or exasperate the stick-slip problems of the logging tool. Control systems and strategies to minimize vibrations and techniques for identifying and inhibiting the sticking of the cable. A system includes a surface actuator and a sensor. The actuator generates an axial wave on the wireline cable which travels down the cable. If there is sticking of the cable, a reflection can also occur at the location of sticking. This shift in the transmission of the wave on the wireline cable is used to identify the onset and/or presence of sticking.Type: GrantFiled: July 10, 2015Date of Patent: October 31, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Murat Ocalan, Jahir Pabon, Daniel Palmer, Hitoshi Tashiro

Patent number: 9187981Abstract: A first wireline tool embodiment includes a segmented tool body having a joint deployed between each adjacent pair of tool body sections. The joint may be configured to extend axially (causing a relative axial displacement of the adjacent tool body sections) when the wireline tool is subject to an axial load. The joint may include, for example, a compliant joint or a protractible joint. The joint may be further configured to cause a relative rotation between the adjacent tool body sections when the wireline tool is subject to axial load. A second wireline tool embodiment includes a plurality of standoff rings deployed about an outer surface of a rigid tool body. The standoff rings engage helical grooves in the outer surface of the tool body such that axial displacement of the tool body causes the standoff rings to rotate.Type: GrantFiled: November 1, 2012Date of Patent: November 17, 2015Assignee: Schlumberger Technology CorporationInventors: Murat Ocalan, Jahir Pabon

Patent number: 8936095Abstract: An apparatus and method of conveying magnetic particles into a wellbore is disclosed. A plurality of particles which are magnetically attracted to one another in response to exposure to a magnetic field are delivered downhole via a degradable material.
