  • Patent number: 10689944
    Abstract: A method of isolating an open-hole section of a wellbore includes positioning, a liner, a valve, and a liner hanger that are attached to a working string adjacent an interface between the open-hole section and a cased section of the wellbore. The method includes injecting cement through the liner and the valve to form a first balanced cement plug within the open-hole section of the wellbore. Generally, the liner, the valve, and the liner hanger are secured within the balanced cement plug. After the balanced cement plug is set, the liner hanger is actuated and the liner, the valve, and the liner hanger are detached from the working string, which causes the valve to close and creates a mechanical barrier between the balanced cement plug and the working string. Additionally, the mechanical barrier is covered in cement to form another balanced cement plug.

  • Patent number: 10661236
    Abstract: A system and method for delivering a treatment fluid to a wellbore by emulsifying the treatment fluid with a continuous fluid in a flowline. The treatment and continuous fluids are combined in a mixer that is separate from containers that retain the fluids. In an example where the mixer is a venturi, the continuous fluid flows into an inlet on an entrance end of the venturi, and the treatment fluid flows into an inlet that is at a flow restriction in the venturi. The continuous fluid experiences a localized decrease in pressure at the restriction, which is due to a localized increase in flow rate at the restriction. The pressure decrease induces the treatment fluid into the venturi, where the treatment fluid is dispersed into droplets within the continuous fluid, and that forms a treatment emulsion. The treatment fluid escapes from within the treatment emulsion when in the wellbore.

  • Patent number: 10584569
    Abstract: A method starts wells with electrical downhole heating and injects solvent(s) or NGL mixes as a preconditioning for a steam injection process. The downhole electrical heating and solvent injection recovers oil and reduces the reservoir pressure. Once oil has been recovered for a period of time and the operating pressure and temperature has been reduced, steam or steam and solvent(s) may be injected to produce high oil recoveries at faster production rates than downhole heating or downhole heating and solvent(s) injection alone. The method reduces heat losses due to steam injection at lower pressure and temperature and therefore, improves efficiency and lowers operating costs. Operating at lower pressure and temperature also reduces the risk of melting the permafrost and consequent well failure issues.
