Patent number: 10119383Abstract: A gas and solids separation system is disclosed to separate gas and solids in a subterranean wellbore thereby preventing the gas and solids from interfering with down-hole equipment. The system includes shrouds and diverters that directs the gas away from the intake of the down-hole artificial lift equipment and also utilizes solids collection chambers and shields which separate and trap solids.Type: GrantFiled: May 11, 2015Date of Patent: November 6, 2018Assignee: NGSIP, LLCInventor: Daryl V. Mazzanti

Publication number: 20170191355Abstract: A two-step artificial lift system and method is proposed which provides for lifting of reservoir fluids without fluid injection using a first step system and lifting of reservoir fluids with fluid injection using a second step system. The second step system reuses the components of the first step system. The system and method aids in lifting reservoir fluids from vertical, deviated, and horizontal wellbores.Type: ApplicationFiled: January 4, 2017Publication date: July 6, 2017Applicant: NGSIP, LLCInventor: Daryl V.

Patent number: 9322251Abstract: A system and method for lifting reservoir fluids from reservoir to surface through a wellbore having a first tubing string extending through a packer in a wellbore casing. The system includes a bi-flow connector in the first tubing string, a second tubing string in the first tubing string below the bi-flow connector, and a third tubing string in the first tubing string above and connected with the bi-flow connector. A fluid displacement device in the third tubing string is configured to move reservoir fluids to the surface. The first tubing string allows pressured gas to move from the surface through the bi-flow connector to commingle with and lift reservoir fluids through annuli defined by the first and second tubing strings and defined by the casing and the first tubing string. The bi-flow connector is configured to allow simultaneous and non-contacting flow of the downward pressured gas and lifted reservoir fluid.Type: GrantFiled: March 10, 2015Date of Patent: April 26, 2016Assignee: NGSIP, LLCInventor: Daryl V.

Publication number: 20110278015Abstract: An artificial lift system removes reservoir fluids from a wellbore. A gas lift system is disposed in a first tubing string anchored by a packer, and a downhole pump, or alternative plunger lift, may be positioned with a second tubing string. A dual string anchor may be disposed with the first tubing string to limit the movement of the second tubing string. The second tubing string may be removably attached with the dual string anchor with an on-off tool without disturbing the first tubing string. A one-way valve may also be used to allow reservoir fluids to flow into the first tubing string in one direction only. The second tubing string may be positioned within the first tubing string and the injected gas may travel down the annulus between the first and second tubing strings. A bi-flow connector may anchor the second string to the first string and allow reservoir liquids in the casing tubing annulus to pass through the connector to the downhole pump.Type: ApplicationFiled: July 25, 2011Publication date: November 17, 2011Applicant: Evolution Petroleum CorporationInventor: Daryl V.

Patent number: 8006756Abstract: An artificial lift system is disclosed for removing reservoir fluids from a wellbore. A downhole pump and a gas lift system are disposed in the wellbore. The gas lift system includes a first tubing string, and the downhole pump may be positioned with a second tubing string. Injected pressured gas from the gas lift system may commingle with and raise reservoir fluids from the wellbore through the first tubing string. The commingled gas and reservoir fluids may be separated in the wellbore, and the reservoir liquids may be brought to the surface through the second tubing string by the pump.Type: GrantFiled: December 10, 2007Date of Patent: August 30, 2011Assignee: Evolution Petroleum CorporationInventor: Daryl V.

Publication number: 20090145595Abstract: An artificial lift system is disclosed for removing wellbore fluids from directional or horizontal wellbores. The artificial lift system incorporates a dual tubing arrangement in which each string contains (respectively) a downhole pumping system or a gas lift system. In one string, a gas lift system, preferably intermittent, is utilized to lift reservoir fluids from below a packer assembly to above a packer assembly. This same tubing string is sealingly engaged to the packer and also contains a concentric inner tubing string which extends through and below the packer into the deviated well bore section. This concentric tubing arrangement provides a conduit for the injection gas and also a conduit for the return of commingled reservoir fluids and injection gas where the commingled fluids exit into the annular void between the dual tubing arrangement and the casing, located above the packer.Type: ApplicationFiled: December 10, 2007Publication date: June 11, 2009Inventor: Daryl V.
