    摘要: A technique facilitates intervention operations in many types of wells including horizontal, multi-zone wells. According to an embodiment, a completion is deployed in a borehole, e.g. a deviated wellbore. The completion comprises a side pocket mandrel having a docking station. In some embodiments, the completion may comprise a plurality of the side pocket mandrels A device, such as an electrically powered device, is removably deployed in the docking station. When the docking station receives the electrically powered device, an inductive coupler or other suitable electric coupler may be used to provide power to the electrically powered device while deployed in the docking station. The electrically powered device also is configured for engagement with a tool which enables an intervention operation by simply removing and replacing the device via the tool.

    摘要: In one possible implementation, fresh hydrochloric acid or (partially) spent hydrochloric acid can be pressurized by a pressure source. The pressurized acid from the acid source is injected into a wellbore during an acidizing operation. In addition, a carbon dioxide source may be provided. Acid from the acid source is combined with carbon dioxide from the carbon dioxide source, and the combined acid and carbon dioxide, pressurized by the pressure source, are injected into the wellbore during the acidizing operation. A processor located at the earth's surface or downhole may be provided. The processor can monitor the relative proportions of carbon dioxide and acid in the acid/carbon dioxide combination, as well as the pressure of the acid/carbon dioxide combination at an injection site in the wellbore. Acidizing operation management decisions can be made based on the monitored relative proportions and/or the monitored pressure.

    摘要: Wireless communication and electromagnetic telemetry between various surface or downhole devices may be provided using two or more dipole antennas. The dipole antennas may be formed, for example, by electrically isolating, for each electric dipole antenna, two electrically conductive portions. The two electrically conductive portions are part of a downhole casing, a downhole liner, a completion, a production tube, or a downhole tool. The two or more electric dipole antennas are disposed in different sections of a completed well, in one or more lateral wells, in different completed wells, or in any combination of those. An electromagnetic signal is transmitting from at least one of the two or more dipole antennas and received at any other of the two or more dipole antennas, thereby providing telemetry or wireless communication between the dipole antennas of the petrophysical devices.

    摘要: In one possible implementation, a steering control module includes a received signal analysis module configured to analyze transducer signals propagated through a formation between a lateral wellbore and an active well undergoing a drilling operation. The steering control module is also configured to utilize the analyzed transducer signals to direct a steering system to steer a drill in the active well in a desired direction. In another possible implementation, a first set of signals detected in an active well undergoing a drilling operation can be received. The first set of signals can be transmitted by at least one transducer array associated with a lateral wellbore, with the lateral wellbore and the active well being separated by a formation. The detected first set of signals can be analyzed to determine an area of interest in the formation.

    摘要: A carrier device is provided for temporary installation downhole in a well. The carrier device is a robust device that is divided by a pressure bulkhead into a first section having an inductive coupler, power electronics, and a telemetry unit, typically all formed using multi-chip-module type electronics, and a second section with at least one test device typically using printed circuit board technology that may include sensors or transducers coupled to a communications bus and/or a power line that extends to the first section via the pressure bulkhead. The carrier further includes a mechanism that permits the carrier to be pulled out of the wellbore, and may include a mechanical locating element, typically adjacent the inductive coupler that permits the carrier to be located in the wellbore so that the inductive coupler will be located adjacent an inductive coupler in, on, or behind a liner or casing of the wellbore.

    摘要: Systems and methods are described for controlling the location where a fracture initiates and the fracture direction at the initiation point. A mechanical device is positioned in a main wellbore or partially or fully in a side hole off of the main wellbore. The mechanical device is actuated so as to contact the formation walls and induce stress in the formation. According to some embodiments, fractures are also initiated using the mechanical device. A hydraulic fracturing process is then carried out to fracture and/or propagate fractures in locations and/or directions according to the actuation of the mechanical device.

    摘要: A technique facilitates active zonal control over the inflow of fluids into a lateral wellbore completion at individual well zones of a plurality of well zones. The completion may comprise a plurality of sand screens through which inflowing fluids pass before entering an interior of the completion, e.g. before entering an interior of a completion base pipe. A control module is positioned along the completion between well zones. The control module is controlled via electrical control signals and is operatively connected with a plurality of intelligent flow control devices which are located along the completion in corresponding well zones. Based on signals received, the control module individually controls the intelligent flow control devices to allow or block flow into an interior of the completion at each well zone.
