Richard L Payne: Slug flow mitigtion for production well fluid gathering system. Atlantic Richfield Company, Michael E Martin, October 26, 1993: US05256171 (32 worldwide citation)

Oil and gas well production flow is gathered in field common line manifolds and conducted through a separator to make a coarse separation of gas from liquid and minimize slug flow in the conduits leading from the manifolds to further separation, treatment and pumping facilities. A liquid level signa ...

Richard L Payne: Fluid slug flow mitigation with partitioned pipe. Atlantic Richfield Company, Michael E Martin, June 21, 1994: US05322551 (8 worldwide citation)

Slug flow is substantially prevented in cylindrical pipes and other conduits by placing a generally flat plate partition extending within the pipe and dividing the pipe into a gas flow space and a liquid flow space. The position of the partition and the cross-sectional flow areas of the gas flow spa ...
