Publication number: 20220329124Abstract: A method and arrangement is disclosed herein for making a stator with 3D printed end turns. The stator includes a stator lamination stack with semi-closed slots. Straight I-pin wire segments are housed in the slots of the stator lam stack and form the in-slot segments of a stator winding arrangement. The end turns of the winding arrangement are provided by a conductive material that is 3D printed material at both axial ends of the straight I-pins. The end turns result in a winding arrangement with diamond coils that are inter-locked. The 3D printing of the end turns makes the winding arrangement possible, as the winding arrangement is configured such that it cannot be inserted into the lamination stack in a radial direction (i.e., via any slot openings at the inner diameter or outer diameter).Type: ApplicationFiled: April 8, 2022Publication date: October 13, 2022Inventors: Gabriel Domingues, Joshua B. Lahrman, Matthew R. Conner, Kirk Neet, David A. Fulton

Patent number: 11333788Abstract: A wellbore trajectory survey, having an ordered plurality of survey points, is acquired. Each of the plurality of survey points has a measured depth, an inclination, and a geographic location of the point in the wellbore corresponding to the survey point. The wellbore trajectory survey is ordered on measured depth. The processor identifies a minimum lateral measured depth (min_LMD), a maximum lateral measured depth (max_LMD). The processor identifies a mid-lateral point (mid_LMP) in the plurality of survey points whose measured depth (mid_LMD) is greater than min_LMD and less than max_LMD.Type: GrantFiled: December 28, 2017Date of Patent: May 17, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Manisha Bhardwaj, Dwight David Fulton

Patent number: 11280176Abstract: A wellbore trajectory survey includes an ordered plurality of survey points, each of which has a measured depth, an inclination, and a geographic location. The wellbore trajectory survey is ordered on measured depth. A minimum lateral measured depth (min_LMD) as a measured depth of a first point in the ordered plurality of survey points for which the inclination exceeds an inclination threshold angle is identified. A maximum lateral measured depth (max_LMD) as a measured depth of a last point in the ordered plurality of survey points for which the inclination exceeds the inclination threshold angle is identified. The processor determines from the wellbore trajectory survey that the wellbore at measured depths between the min_LMD and the max_LMD exhibits porpoising into and out of a formation.Type: GrantFiled: December 28, 2017Date of Patent: March 22, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Manisha Bhardwaj, Dwight David Fulton

Publication number: 20220025753Abstract: The disclosure is directed to methods to design and revise hydraulic fracturing (HF) job plans. The methods can utilize one or more data sources from public, proprietary, confidential, and historical sources. The methods can build mathematical, statistical, machine learning, neural network, and deep learning models to predict production outcomes based on the data source inputs. In some aspects, the data sources are processed, quality checked, and combined into composite data sources. In some aspects, ensemble modeling techniques can be applied to combine multiple data sources and multiple models. In some aspects, response features can be utilized as data inputs into the modeling process. In some aspects, time-series extracted features can be utilized as data inputs into the modeling process. In some aspects, the methods can be used to build a HF job plan prior to the start of work at a well site.Type: ApplicationFiled: December 27, 2018Publication date: January 27, 2022Inventors: Peyman Heidari, Manisha Bhardwaj, Harold Grayson Walters, Dwight David Fulton
