Abstract: Described herein are methods for accelerating the start-up in SAGD type processes wherein the volume between the injector and the producer is preheated utilizing open-holes drilled between wells. The recovery of hydrocarbons is also improved due to a viscous fluid drive in the open-holes during SAGD operations.

Abstract: The invention relates to a process for treating an aqueous solution from a subterranean formation of an oil and gas operation. The aqueous solution can be removed from the subterranean formation and treated in a heated centrifugal separator. The heated centrifugal separator can separate the kinetic hydrate inhibitor from the aqueous solution, and then the aqueous solution can be reintroduced into the subterranean formation.

Abstract: A method of performing notch compensation and a system to perform notch compensation for a first seismic streamer are described. The method includes disposing the first seismic streamer at a first depth, where the seismic streamer includes a first set of sensors to receive reflections resulting from a seismic source, the reflections indicating a notch at a frequency. The method also includes disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer including a second set of sensors to receive reflections resulting from the seismic source. The method further includes processing the reflections received by the first set of sensors and the second set of sensors together to derive the match filter, and applying the match filter to the reflections received by the first set of sensors of the first seismic streamer to compensate for the notch.

Abstract: The invention relates to the decommissioning of hydrocarbon wells. It concerns the artificial promoting or inducing of creep in the overburden formation 3 surrounding an oil well 1, so that the formation rock 3 encroaches against the casing 5 to form a seal. This avoids the need to plug the annulus between the casing 5 and formation 3 with cement. The overburden may be caused to creep by reducing the pressure in the annulus, by applying heat to the overburden rock or by stressing the rock repeatedly to cause fatigue in the rock 3.

Abstract: The invention relates to a system and method for alloy-based molten material to be delivered to the multilateral junction, wherein the molten materials, such as a eutectic or non-eutectic alloy, is flowed into the junction area and forms a durable seal upon cooling. An expanding alloy may be utilized, which expands upon solidification and which has a melting temperature that is higher than the maximum anticipated well temperature, which alloy is placed within a cavity in the well and held at a temperature above the melting point of the alloy, whereupon the alloy is cooled down to the ambient well temperature and thereby solidifies and expands within the cavity.

Abstract: The invention relates to a system, method and apparatus for removing heavies from natural gas. Natural gas and an external rich reflux gas feed are processed in a single column refluxed absorber. A bottoms stream is routed to a first heat exchanger and then to a stabilizer column where an overhead stream from the stabilizer column is routed through a condenser for partial separation into an overhead stream. A rich solvent may be introduced to the stabilizer column. The overhead stream is routed through a condenser for partial separation into a stabilizer reflux and a second overhead stream lights. The second overhead stream lights is routed to a heat exchanger and then routed to a partial condenser where the stream is separated into a heavies rich reflux stream, a distillate stream and heavies treated natural gas stream. The rich reflux is routed through a heat exchanger and the rich reflux is pumped to the single column refluxed absorber to be introduced into the single column refluxed absorber as the external rich reflux gas feed.
