Abstract: A connector guard is provided to protect one or both downhole connectors during wellbore run in prior to mating downhole. The connector guard may comprise dissolvable or degradable material and include an engagement sections and a removal feature. The connector guard may be dissolved or degraded via a reactive agent or temperature either introduced downhole proximate to the guards or contained within a chamber included in or created by a connector guard. The connector guard may be further coupled by a non-reactive cover in order to control the rate of reaction of the dissolvable material. The cover may be breached prior to mating of the downhole connectors.

Abstract: A technique facilitates a water flood, e.g. dump flood, operation. A standard electric submersible pumping system is deployed in a wellbore to draw water from an aquifer or water source zone along the wellbore. A shroud and a crossover port are used in combination with the submersible pumping system to redirect pumped water downwardly along an isolated flow path. The downward flow of pumped water is directed along the wellbore and injected into a desired, injection zone to facilitate recovery of oil or to perform other types of water flood operations.

Abstract: To determine fluid flow information associated with a well, data from plural discrete temperature sensors in zones without radial fluid flow in the well are received. The fluid flow information associated with the well is derived by combining the received data from the plural discrete temperature sensors with reservoir data that is independent of the fluid flow. That information can be further enhanced by monitoring the changes of temperature data over time.

Abstract: A system for completing water injection wells includes an injector well completion system. In an embodiment, an injector well completion system for liquid injection in a formation includes a casing string disposed in a wellbore having a tubing bore. The casing string includes a casing and a sliding sleeve. The sliding sleeve has a pressure control valve having open and closed positions, an actuator mandrel having a flow control device, and an injection pressure communication port. The open position of the pressure control valve actuates the actuator mandrel to align the flow control device and the injection pressure communication port to inject liquid from the tubing bore to the formation and generate fractures in the formation.

Abstract: Techniques are provided for sealing a communication line within a device positioned in a wellbore. The communication line may be continuous and extends through a pass-through arranged generally longitudinally through the device. Swellable sealing material is positioned about and/or over the communication line which is placed in the pass-through of the device to form and maintain a secure seal once the device is submerged in a fluid that causes the swellable sealing material to expand.
