摘要： A chemical dispensing system for delivering a chemical dose into a water resource is provided herein. The system includes a dispensing housing, a support feature, and an electrical circuit. The dispensing housing includes at least one compartment that is adapted to retain a chemical dose. The compartment is substantially sealable from an ambient environment that is outside of the compartment. The compartment is independently openable and closable to directly expose the compartment to the ambient environment and enable release of contents retained therein in the open position and to substantially prevent release of the contents retained therein in the closed position. The support feature facilitates suspension of the dispensing housing above a surface of the water resource. Opening of the compartment is controllable through the electrical circuit.

摘要： A method for placing ball sealers within a well formed within a subterranean formation for sealing holes in a casing of the well is carried out by performing at least one of two operations. The first operation involves providing a tag with at least one ball sealer or a carrier fluid containing the at least one ball sealer to facilitate monitoring of the location of the ball sealer. A tag monitoring device is provided within the well for monitoring the location of the tag. The ball sealer and carrier fluid with the tag are introduced downhole into the well. Information from the monitor device regarding the location of the tag is communicated to a remote monitoring location to the thereby provide an indication of the location of the tag within the well to a surface location. In the second operation a container is provided within the well at a known location downhole within the well. The container contains at least one ball sealer. The ball sealer or sealers are released from the container within the well at the known location in response to an instruction initiated from a surface location.

摘要： The current application discloses assemblies and methods for monitoring the downhole condition of a subterranean formation subject to a treatment such as hydraulic fracturing. The method comprises deploying a sensor to a position proximate to the treatment zone of the subterranean formation, maintaining the sensor below or within the flow path of the treatment fluid applied to the treatment zone, and recording a measurement by the sensor. In some cases, the sensor is hosted in an elongated housing and the outer diameter of the elongated housing is about 10% to about 70% of the inner diameter of the flow path of the treatment fluid applied to the treatment zone. In some cases, the flow rate of the treatment fluid is controlled. Therefore, the conveyance device of the sensor can be protected from damage or breakage caused by the erosion, jetting effects or drag force of the treatment fluid.
