Abstract: A limited entry perforating phased gun system and method for accurate perforation in a deviated/horizontal wellbore is disclosed.                                              The system/method includes a gun string assembly (GSA) deployed in a wellbore with shaped charge clusters. The charges are spaced and angled such that, when perforated, they intersect at a preferred fracturing plane. Upon fracturing, the fractures initiate at least principal stress location in a preferred fracturing plane perpendicular to the wellbore from an upward and downward location of the wellbore. Thereafter, the fractures connect radially about the wellbore in the preferred fracturing plane. The fracture treatment in the preferred fracturing plane creates minimal tortuosity paths for longer extension of fractures that enables efficient oil and gas flow rates during production.

IPC: C12N5/07
Filed: 2015-05-26
Abstract: L'invention concerne un procédé de culture ou d'accroissement in vitro de tissu humain ou animal (2, 2'). Le procédé consiste à : obtenir un échantillon de tissu humain ou animal ; réduire la taille du tissu (21, 21') de l'échantillon ; générer un ensemble en plaçant le tissu de taille réduite sur un échafaudage ou un hydrogel (22, 22') ; disposer l'ensemble à l'intérieur d'une chambre de culture d'un système de perfusion 3D (23, 23') ; et perfuser l'ensemble dans le système de perfusion 3D pendant un temps prédéfini (24, 24'). Le procédé selon l'invention permet de préparer et de cultiver directement, in vitro, des spécimens de tissu frais pour une culture hautement efficace in vitro à l'aide d'un système de bioréacteur à perfusion. Étant donné que des cellules uniques de tissu subissent dans la plupart des cas une mort cellulaire in vitro en raison de l'absence de signaux microenvironnementaux, l'utilisation de tissu de taille réduite, comprenant des amas de cellules et des fragments tissulaires de centaines de cellules, peut aider à empêcher la mort cellulaire in vitro ainsi qu'à maintenir le microenvironnement tissulaire initial hétérogène, constitué de types spécifiques de cellules, tels que des cellules épithéliales, du stroma et immunes ensemble. Ainsi, le procédé selon l'invention peut cultiver efficacement tout le tissu au cours du temps, ce qui permet ainsi la survie des types de cellules d'origine.
