Abstract: A self-deployable apparatus for facilitating collecting data from multiple depths of water bodies. Further, the self deployable apparatus comprises a main body, substances, a sensor, a storage device, and a power source. Further, the substances in amounts are to be disposed in a second interior space of the main body for sinking the self-deployable apparatus to a depth of water body. Further, the amounts of the substances undergo a thermochemical reaction at a temperature for producing a gaseous substance. Further, a check valve of the main body expels a portion of the gaseous substance from the second interior space for rising the self-deployable apparatus to a surface of the water body. Further, the sensor generates sensor data based on detecting a parameter of a water sample. Further, the storage device stores the sensor data. Further, the power source powers the sensor and the storage device.

Abstract: A method for producing hydrocarbons in a subterranean well useful for observing properties of one or more subterranean zones, includes the steps of: (a) installing a lower straddle packer in a vertical well section below a junction with a lateral well section; (b) installing an upper straddle packer in a vertical well section above the junction with the lateral well section; (c) conveying hydrocarbons from the lateral well section to the surface with a tubing; (d) observing pressure information in at least one zone with a pressure gauge located in the vertical well section below the lower straddle packer; and (e) obtaining information in the at least one zone with logging equipment run through the tubing. A sidetrack window may be installed in the tubing between the lower straddle packer and the upper straddle packer for providing access to the lateral well section.
