Abstract: A social networking system extends the reach of an ad by allowing an advertiser to seed a search for suggesting targeting criteria for an ad. Using the seeds, the social networking system identifies a set of seed objects from a social graph. The social networking system traverses the social graph to compute the similarity between the seed objects and candidate objects related to the seed objects. Based on the computed similarity, the social networking system suggests a set of target objects to the advertiser. The social networking system receives a selection of one or more target objects from the advertiser. From the selected target objects the social networking system determines one or more targeting criteria for the ad, so users with an edge in the social graph to any of the selected target objects are eligible to receive the ad.

Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. The fracturing system includes an isolation sleeve and fracturing spool. The isolation sleeve inserts in an axial bore of the fracturing spool, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A groove in an inner surface of the fracturing spool receives an annular seal for sealing between the isolation sleeve and fracturing spool. Injecting a viscous fluid into the groove energizes the seal, and blocks high pressure fracturing fluid from flowing between the isolation sleeve and fracturing spool.
