    Abstract: A bottom discharge ESP is disposed within a pod casing. The pod casing is adapted to connect to and support the weight of downstream tailpipe tubing sections so the ESP does not have to support the same. The ESP may be suspended within the pod interior space by a supporting tube disposed above the ESP and extending into the pod interior space. The ESP includes a discharge tube with a seal assembly that engages a seal bore formed in the bottom end of the pod and cooperating with an interior surface of the tailpipe tubing to convey pumped injection fluid downward to the tailpipe tubing. Part of the pod casing may be perforated to allow injection fluid to flow into the pod interior space. Alternatively, perforated tubing joints or sliding sleeves may be provided on an upper tube to permit flow of injection fluid to the interior of the pod.

    Abstract translation: 底部放电ESP设置在荚壳体内。 荚壳体适于连接并支撑下游尾管管段的重量，因此ESP不必支撑它们。 ESP可以通过设置在ESP上方并延伸到荚内部空间中的支撑管悬挂在荚内部空间内。 ESP包括具有密封组件的排放管，该密封组件接合形成在容器的底端中的密封孔并与排气管的内表面配合，以将泵送的注射流体向下输送到尾管。 荚壳体的一部分可以被穿孔以允许注射流体流入荚内部空间。 或者，穿孔管接头或滑动套管可以设置在上管上，以允许注射流体流到荚的内部。

    Abstract: An anti-rotation device for and method of preventing rotation of alternate deployable electrical submersible pumps (ESP's) vvithin a well casing. This anti-rotation device includes a mandrel connected with the ESP (or ESP string) and a torque anchor connected with an inner surface of the well casing. A portion of the mandrel is configured to engage an inner surface of the torque anchor is such a manner as to prevent rotational movement of the mandrel (and ESP) within the well casing. The mandrel may be of variable length and configured to allow variable and selective positioning of the ESP within the well casing. The interaction of the mandrel and the torque break also provides for alignment of the ESP within the well casing. Additionally, it absorbs and dissipates pump induced torque for the ESP.

    Abstract: A well-logging system for a geological formation having a borehole therein includes a well-logging tool to be positioned within the borehole. The well-logging tool includes electrical current flow pads to press outwardly against adjacent portions of the borehole and establish respective current flow paths therethrough, and sensors to sense pressure and current flow for each of the electrical current flow pads. The system may also include a processor coupled to a display to display an image including icons representative of the sensed pressure and current flow for each of the electrical current flow pads. The icons may be assigned different colors to indicate status.

    Abstract: An ion source for use in a particle accelerator includes at least one cathode. The at least one cathode has an array of nano-sized projections and an array of gates adjacent the array of nano-sized projections. The array of nano-sized projections and the array of gates have a first voltage difference such that an electric field in the cathode causes electrons to be emitted from the array of nano-sized projections and accelerated downstream. There is a ion source electrode downstream of the at least one cathode, and the at least one cathode and the ion source electrode have the same voltage applied such that the electrons enter the space encompassed by the ion source electrode, some of the electrons as they travel within the ion source electrode striking an ionizable gas to create ions.
