Abstract: A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands, which can result in leak paths on the ID of the o-rings. The o-rings provide a gas-tight sliding seal that can withstand temperature changes from ?25° C. to 40° C.

Abstract: A system for automatically monitoring and performing diagnostic procedures on a conduit of a hydrocarbon well operation is disclosed. System examples can use a combination of sensors, data acquisition devices, and computing devices to provide fully automated conduit monitoring and diagnostic procedures that can be based on a variety of different triggering conditions. At least one sensor can be located in fluid communication with the interior of a conduit. A pressure wave traveling through the conduit as a result of deliberate action or a natural occurrence is reflected by abnormal conditions in the conduit. The sensor can receive signals comprising the pressure wave reflections. Pressure data generated by the sensor in response to receiving the signals may be automatically collected and subsequently provided to a computing device that can analyze the pressure data and determine the existence and nature of one or more abnormal conditions of the conduit.

Abstract: A system for benchmarking a flowline temperature model using acoustic detection techniques is disclosed. A predicted velocity of a pressure wave introduced into the flowline by an acoustic detection subsystem can be determined using temperature data from a known temperature model, and an expected time of flight of the pressure wave to a flowline target feature can be calculated using the predicted velocity. An actual time of flight of the pressure wave to the target feature can also be observed from received pressure data, and when the system detects a difference between the actual and predicted times of flight, an actual pressure wave velocity may be calculated based on the actual time of flight. A corrected temperature value corresponding to the actual pressure wave velocity may be subsequently calculated, and the known temperature model can be revised by substituting the corrected temperature value for the predicted temperature value.

Abstract: A machine learning-based system for automatically locating and tracking a transient object in a conduit of interest associated with a hydrocarbon well operation. The system may train a machine learning model using pressure data received from a conduit monitoring system that operates by introducing a pressure wave into the fluid within a conduit and using a sensor to measure the magnitude of pressure waves reflected by a transient object in the conduit. The pressure data can be filtered to remove noise and focus on a frequency range of interest prior to being used to generate a training dataset for training the machine learning model. The machine learning model may be trained to generate a predictive model that can predict the location and movement of a transient object in a conduit of interest based on new pressure measurements associated with the conduit of interest.

Abstract: A machine learning-based system for automatically identifying and locating depositions or leaks in a conduit associated with a hydrocarbon well operation. The system may train a machine learning model using a training dataset comprising a multitude of measured pressure data samples received from a conduit monitoring system that operates by introducing a pressure wave into a conduit and using a sensor to measure the magnitude of pressure waves reflected by surfaces or objects in the conduit. The pressure data samples can be filtered to remove noise and focus on a frequency range of interest prior to being used to train the machine learning model. The machine learning model may be trained, using key attributes of the pressure data samples, to generate a predictive model that can predict a deposition or leak in a conduit of interest based on new measured pressure data associated with the conduit of interest.
