A method and/or apparatus for determining the mass flow rate and the quality of steam in a flowing line. It involves directing the total flow to a liquid-vapor separator. The separated vapor and liquid have the flow of each metered and the flow of one regulated so as to hold the level of the separat ...

Wann Sheng Huang, Alfred Brown: Method for forming a gravel packed horizontal well. Texaco, Robert A Kulason, James J O Loughlin, Robert B Burns, November 19, 1985: US04553595 (29 worldwide citation)

Method for forming a gravel pack in-situ about a horizontal well in a sandy formation. The gravel pack is formed in two separate steps so that part of the pack will function as a foundation for slidably inserting and supporting the well liner. Thereafter, the remainder of the pack is completed about ...

Alfred Brown, Ching H Wu, Jack H Park: Method for recovering viscous petroleum. Texaco, Carl G Ries, Thomas H Whaley, Jack H Park, October 5, 1976: US03983939 (22 worldwide citation)

Recovery of viscous petroleum from thick formations is especially difficult because thermal fluids or solvents needed to mobilize the viscous petroleum tend to channel through high permeability streaks in the formation, thereby bypassing large portions of the petroleum saturated formation. By formin ...
