摘要： Provided herein are systems and methods to detect pipeline leaks. The systems and method can identify a pipeline pressure surge by applying a trained convolutional neural network (CNN) model for classifying pipeline pressure measurement images on each sensor site of a plurality of sensor sites, transfer pressure surge information obtained from at least a portion of the plurality of sensor sites to a cloud site, and determine whether the identified pressure surge is a pipeline leak at the cloud site using the pressure surge information. The plurality of sensor sites collect pipeline pressure measurement data. The pressure surge information corresponds to the identified pipeline pressure surge.

摘要： A system, method, and apparatus are provided for estimating a flux of fugitive gas emissions. The method is performed using a gas analyzer coupled to a sampling wand, where gas enters the inlet tip of the sampling wand prior to being sampled by the gas analyzer. The sampling wand is fixed to a mobile device that includes an inertial measurement unit. Location information from the inertial measurement unit is used to compile a high resolution geo-spatial map of gas concentration levels across a cross-sectional area of a gas plume. A near-field Gaussian plume inversion calculation is then performed to estimate the flux based on the gas concentration data and the location information.

摘要： The present disclosure relates to pipeline corrosion inhibitor optimization and control. In an example, a failure probability representative of a likelihood of a pipeline corrosion failure and a consequence level representative of a consequence from the pipeline corrosion failure can be computed. A risk matrix can be generated and used to identify an inhibitor concentration based on the failure probability and consequence. A dosage of a corrosion inhibitor for mitigating corrosion of a pipeline can be computed based on the inhibitor concentration. In some examples, the dosage of the corrosion inhibitor can be adjusted based on a modification factor computed at least based on a corrosion rate measured for the pipeline.

摘要： A system to retrieve a buoyant leak detector (76) traveling with the fluid flowing in a pipeline (24), includes a catchment device (38) located above the bottom interior of the pipeline. Flexible, elongate manifold structures (30) are constructed with fluid outlet openings (54) extending along the manifold structures. The manifold structures are deployable to lie across the lower inside perimeter of the pipeline, upstream from the catchment device. A source of pressurized air is routed to the manifold structure, whereby air bubbles are emitted from the nozzles of the manifold structure to form a sheet or curtain of air bubbles that flow in the direction downstream of the fluid flow in the pipeline and at an angle upwardly from the location of the manifold structures to cause the leak detector to be deflected by the bubble curtain toward the catchment device.
