One or more images of a tubular being run into a well are captured. The one or more images can be captured by an image sensor. The tubular includes a first tubular section and a second tubular section connected together by a connection. An onsite edge gateway local to the image sensor is configured to perform various operations. Based on the captured one or more images, an elevation of the connection relative to a reference elevation of the well is determined. Based on the determined elevation, an operating condition is determined. It is determined whether the operating condition is included in an automation rule. In response to determining that the automation rule includes the operating condition, a signal is transmitted to drive a controllable device.

A Wheatstone bridge flowmeter is formed on a base substrate with a fluid passageway formed over or through a top surface of the base substrate. Resistors forming the Wheatstone bridge and a heater are arranged in a linear physical arrangement along the passageway, such that two resistors on one side of the Wheatstone bridge are sequentially upstream of the heater and two resistors on the other side of the Wheatstone bridge are sequentially downstream of the heater, establishing a sequential arrangement along the fluid passageway of two of the resistors, the heater and the other two resistors. Heating of the fluid by the heater creates a differential in the temperatures of the resistors, thereby changing the output sensing voltages across the Wheatstone bridge.

A flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.

Methods, apparatuses, and computer program products associated with flow sensing devices are provided. An example flow sensing device may comprise a controller component in electronic communication with a flow sensing component that is configured to: monitor at least one flow sensing component output, detect an air bubble at a location adjacent a surface of the flow sensing component based at least in part on the at least one flow sensing component output, and determine whether the air bubble satisfies an air bubble condition defining one or more predetermined characteristics.

Systems, methods, and computer program products can be used for visualizing the behavior of flow of two or more fluid phases, wherein a fluid phase behavior is represented in a visualization. One of the methods includes determining an occupation time, which is the amount of elapsed time from when a fluid phase first occupies a particular location until a second time. The method includes generating data for a visualization, with a location in the visualization corresponding to the particular location, and with the generated data for that location in the visualization indicating the occupation time.

A flow meter comprises a capillary, a first and second fluid flow marker, and one or more sensors. The capillary has a longitudinally extending fluid receiving space, with a first end and a second end. The first and second fluid flow markers are immiscible and are positioned in the fluid receiving space. The one or more sensors are positioned along the capillary. A method for measuring flow rates comprises the steps of introducing a first liquid into a flow meter. That first liquid flows into the fluid receiving space at the first end of the capillary thereby displacing the first fluid flow marker and the second fluid flow marker towards the second end of the capillary. The interface between the first fluid flow marker and the second fluid flow marker is measured with one or more sensors to determine the flow rate of the first liquid.

A method for normalizing a chemical tracer response in a zone can include measuring a concentration of the tracer as produced from a proximal zone, measuring a concentration of a reference tracer as produced from the proximal zone, and applying a mathematical correction to a concentration of the tracer as produced from the zone. Another method can include normalizing a chemical tracer concentration to a reference tracer concentration, and then allocating flow to a zone corresponding to the tracer based on the normalized tracer concentration. Another method can include injecting a first chemical tracer into a first wellbore reference zone and into additional producing zones of the first wellbore, injecting a second chemical tracer into a second wellbore reference zone and into additional producing zones of the second wellbore, and injecting a third chemical tracer into each of the additional producing zones of the first and second wellbores.
