Abstract: A method of measuring a pressure of a fluid adjacent a wall of a pipe or vessel. A transducer is attached to the wall of the pipe or vessel. A signal is transmitted by the transducer at a characteristic frequency via a plurality of guided wave modes. The characteristic frequency is a frequency at which the guided wave modes are separated in time from each other when received. The signal is received after the plurality of guided wave modes travel in or through the wall a predetermined number of times. The signal has a signal receipt time after the predetermined number of times. The pressure of the fluid is calculated using the signal receipt time.

Abstract: Herein disclosed are methods and systems related to processes for managing power consumption by a plurality of wells in a hydrocarbon field. The plurality of wells are used to extract hydrocarbons from the field. An exemplary process comprises gathering operating information about conditions in the hydrocarbon field. The process further comprises receiving requests to operate from each of the plurality of wells. The requests to operate include a readiness indicator that provides a readiness state. The process further comprises evaluating the requests to operate based on the operating information and the readiness state of each of the wells. The requests to operate are responded to in order to control power consumption by the plurality of wells.

Abstract: Methods for utilizing and regenerating solvent mixtures for dissolving elemental sulfur within hydrocarbon wells are described herein. One method includes providing a solvent mixture including an elemental sulfur solvent fraction including disulfide compound(s), as well as an odorant fraction including a lactate ester solvent. The method also includes injecting the solvent mixture into a hydrocarbon well such that the elemental sulfur solvent fraction dissolves elemental sulfur deposited on well components, as well as collecting the resulting spent solvent mixture, which includes thiols and residual lactate ester solvent, within a spent solvent separator. The method further includes sparging the spent solvent mixture with oxidizer within the spent solvent separator to allow for oxidation of the thiols to produce the disulfide compound(s) using the residual lactate ester solvent (and, optionally, additional lactate ester solvent), as well as regenerating the solvent mixture using at least a portion of the produced disulfide compound(s).

Abstract: A method and system are described for communicating within a system, which includes a plurality of communication nodes disposed along tubular members in a wellbore. The method includes constructing a communication network and installing the communication nodes along the tubular members. The communication nodes are used to monitor for the presence and/or quantity of sand in the tubular members by analyzing how the contents of the tubular members acoustically affect the signals transmitted between the communication nodes.
