A vertical component electromagnetic (EM) borehole flowmeter with the versatility and sensitivity req uired for application at most sites has been developed by the Tennessee Valley Authority (TVA). The prototype TVA EM flowmeters. The book explains the theory, numerical modeling, and applications of a borehole electromagnetic telemetry system, which is used for wireless communication between the downhole tool and the surface control center during oilfield drilling and covers both 2D and 3D electromagnetic.
This report describes the operation and application of the TVA prototype EM borehole flowmeters, including theory, design, calibration, basic field applications, data analysis, and potential. Borehole flowmeters are downhole tools that measure axial flow in a well or borehole.
Desirable flowmeter characteristics include low detection limit, a wide range of operation, accuracy, durability, reliable performance, and a small diameter and length. The recently developed electromagnetic (F.M) flowmeter Cited by: Although this document focuses on the design and application of the electromagnetic flowmeter developed under this project for the measurement of the vertical component of flow within a well, the data collection and methods of analysis apply to other types of vertical component flowmeters.
