Patent number: 10718201Abstract: A system and method for installing casing in a blind horizontal well for blind horizontal directional borings. The system and method may include an example of an offset transmitter sonde assembly that contains an open central passage through which well casing can be inserted, and an example of a drill bit assembly that may be remotely uncoupled from a drill string, leaving the bit in the bore created. Remote uncoupling of the drill bit assembly tends to allow a casing to be installed in the bore while the drill string and bit remain in the bore for support during casing installation. After installation of the casing the drill bit assembly may be uncoupled from the drill string, allowing the drill string to be withdrawn from the bore, with the drill bit assembly remaining in the bore.Type: GrantFiled: March 13, 2018Date of Patent: July 21, 2020Assignee: ELLINGSON DRAINAGE, INC.Inventors: Michael D. Lubrecht, James M. Doesburg, Daniel W. Ombalski, James Ditto

Patent number: 10465486Abstract: An improved well screen with an integrated filter or treatment media assembly. An integrated assembly for use in horizontal well installations in which the well screen may be installed without special procedures, and without necessitating the use of a sand pack. An inner extrusion supports a textile sock that may include reactive material. The material is protected by an outer well screen.Type: GrantFiled: October 19, 2015Date of Patent: November 5, 2019Assignee: ELLINGSON DRAINAGE, INC.Inventors: Michael D. Lubrecht, James M.

Patent number: 10036240Abstract: A drill assembly with a drill body coupled to a drilling string and a sonde body having a least one chamber defined therein for receiving locating electronics therein. In disclosed embodiment, the one or more chambers may be provided and the electronics can include a battery, a sensor, a transmitter, an antenna and connecting wires. One or more secure windows may be provided in the sonde body to allow the locating electronics to wirelessly transmit outside of the sonde body. The electronics may be potted within the chamber with a solidifying potting agent to improve durability of the electronics in a drilling environment.Type: GrantFiled: November 6, 2015Date of Patent: July 31, 2018Assignee: DIRECTED TECHNOLOGIES DRILLING, INC.Inventors: Michael D Lubrecht, James M Doesburg, Daniel W Ombalski

Patent number: 9777467Abstract: A system for a water supply well that incorporates a vertical well with one or more horizontally drilled collectors extending therefrom. All of the horizontally drilled collectors may be constructed using horizontal directional drilling techniques with the main drilling equipment positioned on the ground surface and thereby defining a surface port for accessing the horizontal collector. The horizontal collector may be cleaned and maintained through the surface port without requiring access through the vertical well.Type: GrantFiled: June 6, 2014Date of Patent: October 3, 2017Assignee: DIRECTED TECHNOLOGIES DRILLING, INC.Inventors: Daniel W. Ombalski, James M. Doesburg, James Ditto, Michael D. Lubrecht

Patent number: 6390192Abstract: An integral well filter and screen and a method for making and using it are described. A first embodiment includes a perforated cylindrical well screen with a filter assembly in its interior. The filter assembly includes a pliable filter material bonded to a filter support. The filter support is a plastic lattice rigid enough to hold the shape of the filter assembly and keep the filter material in contact with the inner surface of the well screen, yet deformable enough that the filter assembly can be formed into a shape consistent with the interior of the well screen. A second embodiment includes a well screen with a filter made of a rigid, porous material placed inside the well screen. Because the filter is rigid, it needs no filter support. Methods of manufacturing each of the embodiments are presented.Type: GrantFiled: March 31, 1998Date of Patent: May 21, 2002Assignee: Well, Well, Well, Inc.Inventors: James M. Doesburg, Michael D. Lubrecht

Patent number: 4688999Abstract: A well pump includes a piston and an inlet and/or outlet valve assembly of special structure. Each is formed of a body of organic polymer, preferably PTFE. Each includes a cavity in its upper portion and at least one passage leading from the cavity to the bottom of the block. A screen covers each cavity and a valve disk covers each screen. Flexible sealing flanges extend upwardly and downwardly from the periphery of the piston block. The outlet valve block has a sliding block and sealing fit with the piston rod.Type: GrantFiled: April 8, 1986Date of Patent: August 25, 1987Assignee: Battelle Devepment CorporationInventors: Kenneth R. Ames, James M. Doesburg

Patent number: 4669536Abstract: A groundwater monitoring system includes a bore, a well casing within and spaced from the bore, and a pump within the casing. A water impermeable seal between the bore and the well casing prevents surface contamination from entering the pump. Above the ground surface is a removable operating means which is connected to the pump piston by a flexible cord. A protective casing extends above ground and has a removable cover. After a groundwater sample has been taken, the cord is disconnected from the operating means. The operating means is removed for taking away, the cord is placed within the protective casing, and the cover closed and locked. The system is thus protected from contamination, as well as from damage by accident or vandalism.Type: GrantFiled: September 27, 1984Date of Patent: June 2, 1987Assignee: Battelle Development CorporationInventors: Kenneth R.
