Patent number: 11603748Abstract: A sand separating apparatus for use with a production tubing string includes (i) a housing assembly forming an outer tubular and (ii) an inner tubular within the housing assembly to define an annular passage between the inner tubular and the housing assembly. A helical member occupies part of the annular passage below production openings in the housing assembly whereby a flow of production fluids entering from the wellbore is directed downwardly along a helical path within the annular passage as dictated by the helical member and subsequently upwardly through the inner tubular. The helical member extends radially outwardly from the inner tubular beyond a boundary surface at an outer perimeter of the annular passage to prevent formation of a gap at the tip of the helical member as it wears. A fluid passage in alignment with the helical member extends radially from inside the inner tubular to the annular passage.Type: GrantFiled: May 27, 2022Date of Patent: March 14, 2023Inventor: Brian Ellithorp

Patent number: 11591891Abstract: Pumping of wellbore fluid to a surface may have a detrimental effect on the pump performance due to high gas concentrations in the fluid. A pump system that utilizes a helix gas separator provides greater pump efficiency by effectively removing the gas phase of the fluid. The wellbore fluid received at a pump system is directed from an intake to a gas separator that utilizes a stationary auger. The stationary auger induces rotational motion of the wellbore fluid causing the wellbore fluid to separate into a gas phase and a liquid phase. The stationary auger utilizes a tapered diameter and an opening between one or more helixes or vanes to separate a gas phase more efficiently from a liquid phase of a fluid.Type: GrantFiled: June 22, 2021Date of Patent: February 28, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Casey Laine Newport, Donn Jason Brown, Ketankumar Kantilal Sheth

Patent number: 11560778Abstract: An apparatus and method according to which a perforating gun includes a volume fill body. The volume fill body is positioned in the space between a charge tube and a carrier tube. The fill body occupies at least part, and sometimes all, of the free volume space between the charge tube and carrier tube thereby reducing the free volume space. In certain downhole applications, large free volume space can lead to significant reductions in wellbore pressure, causing dynamic underbalance, which is undesirable. The presence of the volume fill body prevents, or at least reduces, dynamic underbalance and its effects. Also, the volume fill body aligns the charge tube with the carrier tube, further assisting perforation.Type: GrantFiled: July 8, 2021Date of Patent: January 24, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Brenden Michael Grove, Richard Ellis Robey, Christopher C. Hoelscher
