Abstract
A method is for sealing a conduit in a sub terrain well bore, where a fluid is present in the well bore. The method comprises the steps of introducing flexible bodies at a position higher in the well bore than the intended position for the seal and being in fluid contact with the intended position for the seal, the flexible bodies having a density that is higher than the fluid in the well bore, allowing the flexible bodies to settle at the intended position for the sealing, and allowing the flexible bodies to consolidate to form a sealing plug in the conduit. Flexible bodies are for use in the method and a method is for introduction of the flexible bodies.
Claims19
A method for sealing a conduit in a sub terrain well bore, where a fluid is present in the well bore, the method comprising:
- introducing flexible bodies at a position higher in the well bore than the intended position for the seal and being in fluid contact with the intended position for the seal, the flexible bodies having a density that is higher than the fluid in the well bore,
- allowing the flexible bodies to settle at the intended position for the sealing, and
- allowing the flexible bodies to consolidate to form a sealing plug in the conduit.
Elastic bodies for remedial sealing of a subterrain oil or gas well, the elastic bodies being produced from a natural or synthetic elastomer material, wherein the elastic bodies are substantially spherical bodies having a diameter from about 2 to 16 mm.
A method for injection of flexible bodies into a conduit in an oil or gas well, the method comprising:
- filling the flexible bodies into a container, the pressurizing container and connecting the container to a valve opening connected to the conduit to be sealed, and opening the container to allow the flexible bodies provided in the container to flow into the wellbore by means of at least one of gravity, gas flow and vibration.
