Patent number: 10961835Abstract: A method for hydraulically fracturing a subterranean formation includes preparing and sending a first command signal from a master controller to a plurality of pumps of a pump system. The first command signal specifies a flow rate output for each in pump to achieve a first target flow rate for a fracturing fluid being injected into the subterranean formation. A pressure of the fracturing fluid injected into the subterranean formation at the first target flow rate is monitored and, based on the pressure, the master controller determines when to increase a flow rate of the fracturing fluid to a second target flow rate. The master controller prepares and sends a second command signal to the plurality of pumps to specify the flow rate output for each pump to achieve the second target flow rate.Type: GrantFiled: December 30, 2016Date of Patent: March 30, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Mehdi Mazrooee, Matthew Lewis Lahman, Stephen Byrne Persac, Michael Linley Fripp, Mark Allen Adams

Ink-jet print head assemblies with a spacer surrounding an ink fill port and method of manufacturing
Patent number: 10780704Abstract: A print head assembly for an ink-jet printer operable with a continuous ink supply system is disclosed, with an ink compartment, a foam insert, an ink fill port, and a spacer. The ink fill port receives ink fed from an external supply and to be printed by the print head assembly. The ink compartment stores the ink to be printed. The foam insert is in the ink compartment and takes up the ink to be stored. The spacer extends into the ink compartment, provides for the formation of a clearance between the foam insert and the ink fill port and surrounds the ink fill port either completely or with one or more gaps having a gap width. The gap width of none of the gaps presents an aperture angle of more than 25% of 36° with respect to a center of the ink fill port.Type: GrantFiled: July 1, 2016Date of Patent: September 22, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Aidan O'Reilly, Tommy O'Connor, John Oliver, David Kelly, Stephen Byrne -

Patent number: 10436004Abstract: Methods including isolating a first treatment zone comprising an opening into a subterranean formation. A high-viscosity treatment fluid (HVTF) is introduced through the opening and incrementally increased fracturing rate steps (IIFRSs) are applied to create or enhance a dominate fracture, wherein between each IIFRS a downhole pressure slope over time will increase, decline, or stabilize at a measured pressure slope. The measured pressure slope is evaluated to determine whether an increasing pressure slope, a stabilizing pressure slope, or a declining pressure slope exists to determine whether and when to apply a subsequent IIFRS. The result is increasing a volume of the dominate fracture due to efficient dominate fracturing with generated back pressure until a first maximum fracturing rate is reached.Type: GrantFiled: September 23, 2015Date of Patent: October 8, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Philip D.
