    摘要: 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.

    摘要: A chemical injection assembly with telemetric capacity and a single fluid injection line capable of reaching multiple downhole injection points. The assembly may take advantage of downhole power telemetry modules so as to intelligently power and direct actuator valves at any of a number of different injection points. So, for example, the need for cumbersome and expensive usage of different delivery lines dedicated to serve different delivery points with the same fluid may be avoided.

    摘要: Apparatus and methods for completing, treating, and/or producing a wellbore are provided. The apparatus can include a tubular body defining an inner bore, one or more injection inflow control devices, and one or more production inflow control devices. The one or more injection inflow control devices can include one or more first check valves in fluid communication with the inner bore, with each first check valve being configured to allow fluid to flow therethrough from the inner bore to a region of the wellbore, and to substantially block a reverse fluid flow therethrough. The one or more production inflow control devices can include one or more second check valves coupled to the tubular body, each second check valve being configured to allow fluid to flow therethrough from the wellbore to the inner bore and to substantially block a reverse fluid flow therethrough.

    摘要: 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.

    摘要: 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.
