Systems, apparatus, and methods for controlling a well blowout comprising: a flow control device such as a blowout preventer on a wellbore, the primary throughbore of the flow control device comprising internal dimensional irregularities creating a non-uniform flow path in the primary throughbore which as sufficient fluid rate may enhance pressure fluid pressure drop therein; a control fluid aperture fluidly connected with the wellbore for introducing a control fluid through a control fluid aperture and into the primary throughbore while wellbore fluid flows through the wellbore; a weighted fluid aperture positioned in the wellbore conduit below the control fluid aperture for introducing a weighted fluid into the wellbore while control fluid is also being introduced into the wellbore through the control fluid aperture.

Wellbore dynamic top kill

The present techniques are directed to a system and method for generating power and recovering methane from methane hydrates. The system includes a low emissions power plant configured to generate power, wherein an exhaust gas from the low emissions power plant provides a gas mixture including nitrogen and carbon dioxide. The system also includes a methane recovery system configured to recover methane from methane hydrates by injecting the nitrogen and the carbon dioxide from the gas mixture into the methane hydrates.

Power generation and methane recovery from methane hydrates

Systems, apparatus, and methods for controlling a well blowout comprising: a flow control device such as a blowout preventer on a wellbore, the primary throughbore of the flow control device for introducing control fluid into the primary throughbore portion of the wellbore throughbore to create a pressure drop within the primary throughbore sufficient to overcome the flowing blowout fluid pressure within the primary throughbore and optionally introducing control fluid into the primary throughbore using a conduit inserted directly into the wellbore throughbore to further enhance introduction of control fluid into the wellbore throughbore; and optionally a weighted fluid aperture may be positioned in the wellbore conduit, preferably below the control fluid aperture for introducing a weighted fluid into the wellbore throughbore while control fluid is also being concurrently introduced into the wellbore through the control fluid aperture.
