  • Patent number: 5205355
    Abstract: Method and apparatus for pressurizing the top of the valve member of a subsurface safety to equalized pressure thereacross and assist in opening the valve. The apparatus includes a chamber filled with fluid under pressure which is admitted in to the space between the apparatus and a valve when landed in the valve to pressurized the valve. A spring loaded prong on the apparatus urges the valve member of the safety valve to open position. A latch is included which will bypass a top landing nipple and land in a second landing nipple.

  • Patent number: 5024274
    Abstract: An enhanced oil recovery well system and method providing for simultaneous heated vapor or hot liquid injection of usually water into one or more formations in a well through a single conduit. The well system utilizes injection mandrels selected to provide drier steam or wetter steam and hot water to inject for best recovery from a particular formation. One injection mandrel separates and collects wetter steam and hot water from injected steam flow and directs the wet steam and hot water flow through the mandrel while directing steam flow into a formation. The other mandrel has upper and lower means for separating and collecting wet steam and hot water and directs wet steam and hot water flow into a formation while directing steam flow through the mandrel. More than one mandrel may be used for each formation and control means may be installed in either mandrel to control flow into formations. Well systems are monitored and controlled for efficient operation and recovery.
