The small-loop transient electromagnetic method (TEM) refers to a system in which the coil frame length or diameter is less than 2 m. Due inductive effects of multi-turn coils used for both transmission and reception, induced electromotive force measuring increases, causing reduction decay rate an extension shutoff time. This results coupling between primary secondary fields early-time signals, making them difficult separate creating detection blind spot shallow subsurface. opposing TEM...
Bayesian inversion is capable of integrating seismic data, well-log and geological data to obtain a posterior probability distribution function (PPDF) elastic parameters. Due the absorption strata, amplitude attenuation phase distortion inevitably occur during propagation wave, resulting in low resolution data. The traditional linear method based on stationary convolution model, compensation correction are needed be conducted advance. Uncertainties exist both inversion, results cannot...
Small-loop transient electromagnetic (TEM) devices, several meters in size, are increasingly applied to near-surface geophysical exploration space-limited environments. But the transmitter (TX) coil significantly affects early time data acquisition of receiver (RX) during current turn-off, resulting loss shallow signals and creating a significant blind zone problem. We report double-coil decoupling TEM (DCDTEM) device solve this The novel DCDTEM ensures weak primary magnetic flux region...
Data processing techniques in transient electromagnetic (TEM) methods face numerous challenges, such as the problem of 3-D imaging and demand for new data arising from development small-loop TEM devices. We have developed an algorithm based on gradient features derived to address these challenges. found that normalising field responses under appropriate background conditions enables target. Numerical experiments conducted theoretical models validated feasibility this approach highlighted...
