Abstract:
Improved apparatus and methodologies for separating production water arising from conventional oil well production operations, the production water containing less than 1% oil-in-water, where the apparatus and methodologies may include the use of a large separation vessel configured to perform a phase separation mid-stream of a continuous fluid flow path, thereby increasing the overall retention time of the separation vessel.

Claim (Index 1):
A method for separating production water arising from at least one primary separation process following oil well production operations, the production water having at least a water phase and an oil phase between 100 to 10,000 PPM oil-in-water, the method comprising:\n receiving the production water in at least one gravity separation vessel having at least one first fluid tank concentrically nested within at least one second fluid tank, the first and second fluid tanks each having a height, wherein receiving the production water comprises:\n introducing the received production water to the first fluid tank along the entire height of the first fluid tank; and \n directing fluid flow along a first fluid flow path within the first fluid tank at a flow rate of approximately one foot per minute; \n recovering the separated oil phase from the at least one first fluid tank and directing the separated water phase, via at least one fluid conduit, to the at least one second fluid tank; receiving the separated water phase from the first fluid tank in the second fluid tank, wherein receiving the separated water phase comprises:\n introducing the separated water phase to the second fluid tank along the entire height of the second fluid tank; and \n directing fluid flow along a second fluid flow path within the second fluid tank at a flow rate of approximately one foot per minute; \n recovering the separated oil phase from the at least one second fluid tank; and recovering the resulting separated water phase from the at least one second fluid tank, wherein the resulting separated water phase contains less than approximately 50 PPM oil-in-water.
