Various aspects described herein relate to a machine learning based detecting of fracture hits in offset monitoring wells when designing hydraulic fracturing processes for a particular well. In one example, a computer-implemented method includes receiving a set of features for a first well proximate to a second well, the second well undergoing a hydraulic fracturing process for extraction of natural resources from underground formations; inputting the set of features into a trained neural network; and providing, as output of the trained neural network, a probability of a fracture hit at a location associated with the set of features in the first well during a given completion stage of the hydraulic fracturing process in the second well.

The present disclosure provides a flooding composition. In an embodiment, the flooding composition includes in weight percent (wt %) based on the weight of the composition (A) from 10 wt % to 45 wt % of a silane-grafted polyolefin (Si-g-PO). The flooding composition also includes (B) from 5 wt % to 60 wt % of a polyα-olefin oil (PAO oil), (C) from 15 wt % to 90 wt % of a polysiloxane, and (D) from 0.05 wt % to 0.2 wt % of a catalyst.

In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and the at least one securing feature is disposed within a portion of the at least one securing feature passageway.

A fiber optic distribution cable includes a central inner jacket formed from one of a polyvinyl chloride or a low smoke zero halogen material, a plurality of optical fibers disposed within the inner jacket, and a plurality of first strength members disposed within the inner jacket. The fiber optic distribution cable further includes an outer jacket surrounding the central inner jacket, the outer jacket formed from the one of the polyvinyl chloride or the low smoke zero halogen material, and a plurality of second strength members disposed between the outer jacket and the central inner jacket. A fiber density of the cable is greater than 0.65 fibers per square millimeter.

The apparatus for non-contact damping vibration of a vibrating optical fiber moving over an optical fiber path includes an air bearing and an air supply. The air bearing includes a body having an aperture defined by an inner surface and a central axis that passes through the center of the aperture and along which lies the optical fiber path. A plurality of nozzles is distributed around the inner surface and directed toward the central axis. An air conduit within the body is in pneumatic communication with the plurality of nozzles. The air supply is pneumatically connected to the air conduit and is configured to supply pressurized air to the air bearing. The pressurized air is directed through the nozzles to the vibrating optical fiber and impinges on the optical fiber to damp the vibration of the vibrating optical fiber.

A cleaning nozzle includes an inner nozzle housing having a feed passage for carrying cleaning fluid, a plurality of nozzle tips that each define a discharge opening in fluid communication with the feed passage, and an outer nozzle housing received over the inner nozzle housing. The outer nozzle housing includes a plurality of outer nozzle extensions that each extend over one of the nozzle tips. The outer nozzle extensions can be inserted into ports of an adapter, and flow of the cleaning fluid through the nozzle is split between the nozzle tips so that multiple optical connectors that populate the adapter can be cleaned simultaneously in a substantially uniform manner.

Fiber optic connectors, connector housings, connectorized cable assemblies, and methods for the connectorization of cable assemblies are provided with particular cable adapter features, adapter extensions, multi-diametrical sealing flexures, subcutaneous sealing elements, and combinations thereof, for improved connector and cable performance, integrity, and durability.
