  • Patent number: 9938796
    Abstract: The sealing device (1) includes an elongated body (5) adapted to be introduced into a tube-shaped channel (2) and including a sealing fluid placement section (6) arranged between a first and a second annular flow barrier (7, 8). The elongated body further includes a sealing fluid activation section (11) arranged between the second annular flow barrier (8) and a third annular flow barrier (12) and including a sealing fluid activation device (13) adapted to at least initiate or accelerate curing of the sealing fluid (17). In operation, the elongated body may be displaced along the tube-shaped channel until the sealing fluid activation section is placed at a position where sealing fluid has been ejected by the sealing fluid placement section, and the sealing fluid activation device may be activated. Thereby, sealing fluid may be cured at selected locations along the tube-shaped channel after ejection of sealing fluid.

  • Patent number: 9650557
    Abstract: A drilling fluid composition for horizontal directional drilling is a flowable aqueous slurry of biodegradable, non-toxic, preferably edible plant particles. The particle size of the plant-derived particles depends on the drill bit used. The particles should be small enough not to clog the fluid jet orifices in normal use. The slurry is pumped through to the drill bit in a warm or preferably hot state, e.g. 80-100° C. After ejection, the slurry cools rapidly, causing solidification and creating a lining on the tunnel wall.

Upon application of a thermal stimulus the cup reverts to a functional cup seal shape by engaging the rim and parts of the cup to the surrounding wellbore. The shape change can also involve a shortened axial dimension that results in the cup shape moving away from the end ring to which it is unattached. The stimulus is provided with well fluids or artificially through heaters or other techniques. External elongated protective elements can be provided to overlay the cup seal during run and bend outwardly with the cup seal during reversion to its functional shape.

  • Patent number: 8616278
    Abstract: Certain viscous oil reservoirs are too deep to be commercially mined but lack an adequate top seal to employ in situ recovery methods such as SAGD. Without an adequate top seal, gases from the reservoir can rise into overlying aquifers and potentially to the surface. While ice-like hydrates would not normally form above the oil reservoir during in situ recovery, an additive can be added to promote hydrate formation. In this way, a hydrate barrier can be formed to act as a top seal to contain these gases.

Generally the methods comprise placing the flowable material in proximity to a radial wall of a wellbore. The methods also include running an energy generator into the wellbore. In one aspect, energizing the nano-particles in the filter cake causes the nano-particles to be activated, and increases a temperature within the flowable material to a temperature that is greater than an initial circulation temperature of the flowable material.

    Abstract: The methods described herein generally relate to preparing and delivering a fluid mixture to a confined volume, specifically an annular volume located between two concentrically oriented casing strings within a hydrocarbon fluid producing well. The fluid mixtures disclosed herein are useful in controlling pressure in localized volumes. The fluid mixtures comprise at least one polymerizable monomer and at least one inhibitor. The processes and methods disclosed herein allow the fluid mixture to be stored, shipped and/or injected into localized volumes, for example, an annular volume defined by concentric well casing strings.

  • Publication number: 20120006545
    Abstract: The present invention relates to methods and compositions useful for isolating a portion of a wellbore. In one embodiment, a method includes preparing a sealant composition containing two phases. The sealant composition is placed into the wellbore where one phase sets upon subjecting the sealant composition to a thermal source followed by the setting of the other phase.

  • Publication number: 20110247814
    Abstract: Systems and methods used in treating a subsurface formation are described herein. Some embodiments also generally relate to barriers and/or methods to seal barriers. A method used to treat a subsurface formation may include heating a portion of a formation adjacent to a plurality of wellbores to raise a temperature of the formation adjacent to the wellbores above a mobilization temperature of bitumen and below a pyrolysis temperature of hydrocarbons in the formation; and allowing the bitumen to move outwards from the wellbores towards a portion of the formation comprising water cooler than the mobilization temperature of the bitumen so that the bitumen solidifies in the formation to form a barrier.

  • Patent number: 7798222
    Abstract: A system for preventing the migration of unconsolidated and/or loosely consolidated material into a wellbore. Such prevention is accomplished by introducing a well treatment medium comprising an expandable fluid and a bonding agent into an unconsolidated zone proximate the wellbore. The expandable fluid is allowed to expand and flow through the unconsolidated zone while the bonding agent cures, thereby forming a consolidated zone having sufficient porosity to allow fluid flow therethrough.
