  • Patent number: 10738567
    Abstract: Methods of plugging a hydrocarbon well by a through-tubing technique wherein the tubing is left in place, and only very short (<5 m) sections are cut, milled, perforated, ruptured and expanded, or combinations thereof. A blocking device is sent downhole if needed to block a bottom of the plug section, and resin dropped onto the blocking device to make a first plug, then cement is deployed onto said first plug to form a second plug. Therefore, the final interval is plugged with a two material binary plug. Once completed, and both primary and secondary barriers are in place, the well can be closed and the Christmas tree removed. A rock-to-rock plug can be set by removing or partially removing the tubular and the outer casing, or just inner casing/tubulars can be removed if the exterior cement and casing are of sufficient quality.

  • Patent number: 10738592
    Abstract: Systems, apparatus and methods are described for purposes of initiating a response to detection of an adverse operational condition involving a system including a drill rig and an inground tool. The response can be based on an uphole sensed parameter in combination with a downhole sensed parameter. The adverse operational condition can involve cross-bore detection, frac-out detection, excessive downhole pressure, a plugged jet indication and drill string key-holing detection. A communication system includes an inground communication link that allows bidirectional communication between a walkover detector and the drill rig via the inground tool. Monitoring of inground tool depth and/or lateral movement can be performed using techniques that approach integrated values. Bit force based auto-carving is described in the context of an automated procedure.

  • Patent number: 10724355
    Abstract: Downhole tools for isolating and analyzing one or more gases include a gas separation assembly in fluid communication with a gas specific analyzer. The gas separation assembly includes a piston disposed within a housing and a separation volume defined between the piston and the housing. The piston is movable to separate a gas component and a liquid component from a downhole formation fluid within the separation volume. The gas specific analyzer is operable to measure one or more properties of the gas component. In some configurations, the gas specific analyzer is an optical assembly containing a light source, an optical detector, and a gas cell that contains an observation volume. The optical assembly is operable to measure one or more properties of the gas component within the observation volume via the light source and the optical detector.

  • Patent number: 10724356
    Abstract: A downhole separator performs the function of removing gas from liquids before the liquids enter the well pump. The formation fluid enters into a first, lower, chamber, of the separator and exits through channels to helical passageways on the exterior of the separator body. A shroud surrounds the separator body to serve as an outer wall of the helical passageways. Spiraling movement of the fluid forces the heavier liquids outward and causes separation of the lighter gas. The liquids and gas are ejected from the top of the separator body. The separated liquids drain downward by gravity pull to a liquid reservoir. Liquids in the reservoir are driven upward and flow through channels on the exterior of the separator body into a second, upper chamber, in the separator body which is coupled by tubing to the inlet of the pump.

  • Patent number: 10718201
    Abstract: 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.
