Patent number: 9598953Abstract: A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer (“BOP”) rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree (“SSTT”) in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.Type: GrantFiled: December 14, 2012Date of Patent: March 21, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Paul David Ringgenerg, Daniel Dorffer, Dalmo Massaru Wakabayashi

Patent number: 9598954Abstract: Provided herein are various embodiments of casing collar locator (CCL) tools, circuits and methods, which enable a CCL tool to selectively operate in passive or active mode. More specifically, a dual-mode CCL tool is provided herein with a mode selection circuit, which may be coupled between a coil of the CCL tool and a wireline of a well survey system. The mode selection circuit may be generally configured to detect a voltage on the wireline, connect the coil of the CCL tool to the wireline if the detected voltage is less than a threshold voltage, and connect the coil of the CCL tool to an amplifier circuit if the detected voltage is greater than or equal to the threshold voltage. The mode selection circuit described herein therefore enables a single CCL tool to be used for a variety of different downhole operations, including but not limited to wireline logging and well perforation jobs.Type: GrantFiled: June 16, 2016Date of Patent: March 21, 2017Assignee: Penny Technologies c/o VistraInventors: Dalong Zhang, Bulent Finci, George Innes, III

Patent number: 9598955Abstract: Systems and methods are disclosed for obtaining distance related wellbore parameters using pulse-echo measurements. For example, the depth of a wellbore may be computed and/or the length of a tubular string positioned in a wellbore may be determined. In an embodiment, a pulsar is deployed into a wellbore along a length of tubular. Once deployed, a fluid pulse is sent form a surface pulse generator and the transmission time is recorded. The downhole pulsar receives the fluid pulse and, in response, returns a second fluid pulse back to the surface. Surface processing circuitry receives the second fluid pulse and records the reception time. The processing circuitry then process the data to determine the total time for travel, thereby determining the length of the downhole pipe or other tubing.Type: GrantFiled: December 23, 2013Date of Patent: March 21, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Bhargav Gajji, Ankit Purohit, Ganesh Shriniwas Pangu, Keshav Parashuram Pujeri

Patent number: 9598993Abstract: A process for reducing the amount of CO2 released into the atmosphere with the exhaust gas stream produced by the combustion of a hydrocarbon fuel in an internal combustion engine (ICE) used to power a vehicle by capturing at least a portion of the CO2 in a liquid sorbent on board the vehicle, recovering the CO2 from the sorbent and compressing the CO2 for temporary storage on board the vehicle, where the process is operated as a semi-closed system in which the liquid sorbent that captures the CO2 serves as a working fluid and retains the CO2 during the power generation cycle to produce mechanical energy or work, after which the CO2 is desorbed for densification and recovery as an essentially pure gas stream and the working fluid is recycled for use in the process.Type: GrantFiled: June 19, 2015Date of Patent: March 21, 2017Assignee: Saudi Arabian Oil CompanyInventors: Mourad Victor Younes, Wajdi Issam Al-Sadat, Esam Zaki Hamad

Patent number: 9598996Abstract: A method for feeding reducing agent to an exhaust gas mass flow in an exhaust gas treatment device provides a reducing agent feed port, a storage catalytic converter storing reducing agent and an SCR catalytic converter for selective catalytic reduction of nitrogen oxygen compounds in exhaust gas. A first dosing strategy is followed, loading of the storage catalytic converter with reducing agent is monitored and a first target conversion rate is determined based on current loading. Reducing agent is fed according to the first target conversion rate. A current conversion rate obtained with the SCR catalytic converter is determined. The current conversion rate is compared to the first target conversion rate and any deviation is registered. A further dosing strategy, not considering the loading of the storage catalytic converter, is used if the deviation exceeds a first threshold value. A motor vehicle and a stationary installation are also provided.Type: GrantFiled: January 5, 2015Date of Patent: March 21, 2017Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventor: Peter Bauer
