  • WELL COLLAPSE RECONNECT SYSTEM
    Publication number: 20220018202
    Abstract: The invention relates to a method and apparatus for remediating damaged casing or liner in a hydrocarbon well, e.g. caused by collapsed formation. Damaged liner is milled away and a straddle joint (20) located in the exposed ends of liner (8,9), bridging the gap between them and restoring most of the inner diameter. The straddle joint (20) includes cement ports (25) through which cement may be injected into any cavity (4) in the rock surrounding the straddle joint (20), thereby supporting the rock and helping to prevent further collapse.

  • Dissolvable thread tape and plugs for wells
    Patent number: 11053762
    Abstract: Methods of plugging a hydrocarbon well by using degradable plugs plus a degradable tape to ensure pressure testing to 10,000 psi. When the plug is no longer needed, a degradation fluid or fluids are pumped downhole and that fluid or fluids degrade the degradable plugs and degradable tape, thus avoiding the production of any solids large enough to clog or block equipment.
    Type: Grant

    Assignee: CONOCOPHILLIPS COMPANY
    Inventors: Gregory E. Gill, Charles Colpitt
  • Degradable pump in shoe
    Patent number: 10605043
    Abstract: By incorporating a dissolvable or degradable material into the wiper dart and/or float equipment, a fluid can be pumped during the cement phase (or spotted by other means) to begin degradation of the dissolvable material. Once the material is dissolved, a flow path is exposed, allowing communication to the backside or formation of the wellbore through the plug set and shoe track.
