摘要： Embodiments of the invention provide an irrigation pop-up with a flexible stem which may be a pulsating or conventional non-pulsating irrigation sprayer or sprinkler. The flexible stem enables an extended stem to be bent instead of being severed, as experienced by traditional irrigation systems, if impacted by an outside force. In one embodiment, the flexible stem contains a lower rigid segment and an upper rigid segment, each having a passageway extending from an inlet, through the segment, to an outlet. An elastic hollow member, such as a rubber tube, is coupled to and in fluid communication with the passageways of the lower and upper rigid segments. Therefore, a water flow path extends from the water inlet, through the passageway within the lower rigid segment, through the channel of the elastic hollow member, through the passageway within the upper rigid segment, and out through the nozzle, such as a sprayer or sprinkler.

摘要： Methods and systems for evaluating integrity of a tubular located within a wellbore are provided. The method includes measuring an operation parameter of the wellbore, measuring a feature of the tubular two or more times to produce an integrity log each time the feature is measured, and determining a tubular integrity analysis for the tubular by using the integrity logs and the operation parameter. The tubular integrity analysis contains parameter limitations for the tubular. The method also includes determining if tubular integrity is within or outside the parameter limitations. If the tubular integrity is within the parameter limitations, then determine a duration of integrity for the tubular. If the tubular integrity is outside of the parameter limitations, then determine a location on the tubular for loss of tubular integrity.

摘要： Methods for producing a swellable packer in a downhole environment are provided. A method includes introducing a treatment fluid containing a polymeric composition into a wellbore within the downhole environment and exposing the polymeric composition to an acid to produce a swollen polymeric material within the downhole environment. The polymeric composition contains a reaction product of at least one or more monomers, one or more comonomers, and one or more crosslinkers. The acid can be in situ formed from an acid precursor introduced into the downhole environment.

摘要： Methods and systems for characterizing fractures in a subterranean formation are provided. The method includes introducing an encapsulated explosive unit into a casing located in a wellbore within the subterranean formation and maintaining the encapsulated explosive unit in a stage of the casing. The method also includes detonating the encapsulated explosive unit within the stage to generate a pressure wave that passes through a group of perforations and into the fractures and measuring a reflected pressure wave using a pressure sensor coupled to the bridge plug to produce a pressure measurement. The method further includes converting the pressure measurement into an acoustic signal correlated with the pressure measurement by an acoustic signal generator contained in the bridge plug and transmitting the acoustic signal to apply acoustic pressure on a fiber optic cable coupled to an exterior surface of the casing.
