Abstract
A method and system for producing steam for use in heavy hydrocarbon recovery operations. Water, containing impurities, produced from the well is separated from hydrocarbons and other materials, and subsequently directly passed to a produced water boiler with online pigging. The boiler is indirectly heated by means of a hot flue gas, such as a gas turbine exhaust, which produces electricity (for powering a central processing facility, or alternatively a burner to heat the boiler) and exhaust heat for heating the boiler.
Claims28
A method for generating steam for use in a thermal hydrocarbon recovery operation, the operation comprising at least one hydrocarbon recovery well, the method comprising the steps of:
- producing produced materials from the at least one hydrocarbon recovery well;
- treating the produced materials to separate water from the produced materials;
- feeding the water into steam generation means;
- providing a heat source;
- providing heat exchange means between the heat source and the steam generation means;
- transferring heat from the heat source to the steam generation means via the heat exchange means;
- allowing the heat to increase the temperature of the steam generation means;
- and
- heating at least a portion of the water in the steam generation means to or above the water's boiling point to generate steam.
A steam generation system for use in thermal hydrocarbon recovery operations wherein the operations comprise at least one hydrocarbon recovery well, the system comprising:
- produced materials treatment means configured to separate water from produced materials produced from the at least one hydrocarbon recovery well;
- feeding means for feeding the water to steam generation means;
- a heat source;
- and
- heat exchange means between the heat source and the steam generation means for transferring heat from the heat source to the steam generation means, allowing heat to increase the temperature of the steam generation means and heating at least a portion of the water in the steam generation means to or above the water's boiling point to generate steam from the water.
