Direct Chemical Injection Systems
Mississippi Power's Kemper County vitality facility, or Kemper Project, was to have been a first-of-its-kind plant in the U.S. that was anticipated to be online in 2015. Its coal gasification component has since been canceled, and the plant has been transformed to a conventional natural fuel mixed cycle energy plant without carbon capture. Department of Energy and other companions with the intention to develop cleaner, cheaper, more reliable strategies for producing electricity with coal that additionally assist EOR production. The gasification technology was designated to gasoline the integrated gasification combined cycle power plant. Additionally, the unique location of the Kemper Project, and its proximity to grease reserves, made it a perfect candidate for enhanced oil restoration.
Fire flooding works greatest when the oil saturation and porosity are high. Continuous injection of air or different gasoline combination with excessive oxygen content will preserve the flame entrance. As the hearth burns, it moves via the reservoir toward production wells. Heat from the hearth reduces oil viscosity and helps vaporize reservoir water to steam.
The steam, sizzling water, combustion gas and a bank of distilled solvent all act to drive oil in front of the fireplace toward manufacturing wells. Steam flooding (see sketch) is one technique of introducing warmth to the reservoir by pumping steam into the nicely with a sample similar to that of water injection. Eventually the steam condenses to sizzling water; within the steam zone the oil evaporates, and in the sizzling water zone the oil expands. As a end result, the oil expands, the viscosity drops, and the permeability increases.
Gas injection accounts for nearly 60 p.c of EOR production in the United States. As manufacturing continues, the reservoir pressure will decrease, and hence the differential pressure will lower. This lower in pressure might necessitate the usage of a synthetic lifting system to proceed manufacturing.
The commonest synthetic carry for use in main recovery is the rod pump. The rod pump employs a beam-and-crank meeting to create a reciprocating movement which transfers to vertical carry via a series of plungers and valves. This method is the traditional oil derrick with its distinctive bobbing horse head.
