Abstract: A perforation tool for use in a well bore is described herein. The perforation tool comprises a housing; a plurality of frames that fit inside the housing, each frame having a cylindrical shape with a central axis and a plurality of liners, each liner having an axis perpendicular to the central axis, wherein the axes of the liners of each frame are disposed in a plane perpendicular to the central axis, and the frames are axially stackable; an electrical conductor disposed along a central passage of each frame; a plurality of shaped charges secured in the liners of the frames; a bulkhead member disposed in the housing and forming a seal with the housing; and an initiator module disposed in the housing with the bulkhead member between the initiator module and the plurality of frames.

Abstract: In some aspects, the disclosure is directed to methods and systems for synchronized multi-client content delivery, and a content selection system based on individual and aggregated scores for the content items, to generate bundles or sets of content items having approximately corresponding scores. Server timers and local timers on client devices may be synchronized via notifications, and timer durations dynamically adjusted when client requests and responses are sent prior to client-side timer expiration, but received after server-side timer expiration, indicating communication latency has caused desynchronization. Timers may be adjusted on a global basis or per-client device basis. Through scoring and bundling, sets of content items that may be relevant to approximately an equal share of the recipient client devices may be selected and transmitted.
