In field seismic data, abnormal environmental noise from the acquisition environment often is unavoidable, and its characteristics are complex. Abnormal has a strong amplitude (tens of thousands times average amplitudes) masks effective signal. The traditional method for removing such relies on energy scanning to identify location. However, cannot always accurately due sudden change at locations first-breaks surface waves. A deep learning been developed. presence with large also results in...
Artificial Intelligence models encoding biology and chemistry are opening new routes to high-throughput high-quality in-silico drug development. However, their training increasingly relies on computational scale, with recent protein language (pLM) hundreds of graphical processing units (GPUs). We introduce the BioNeMo Framework facilitate AI across GPUs. Its modular design allows integration individual components, such as data loaders, into existing workflows is open community contributions....
Recent advances in distributed acoustic sensing (DAS) technology have allowed more intense measurements of subsurface and environment events, providing improved geohazard monitoring characterization. This study discussed the evaluation enabled by DAS-vertical seismic profiling (DAS-VSP) system East China Sea, China. Taking advantage a continuous recording vibrational wavefields through strain deformation fiber deployed along borehole, DAS-VSP is considered an emerging promising alternative...
The quality of wavefield separation on vertical seismic profiling (VSP) data directly affects subsequent imaging and inversion processes. However, the traditional methods have various defects in separating upgoing downgoing waves. application deep learning brings another train thought to solve related problems. methods, such as f-k filtering Radon transform, produce results with spatial aliasing inaccurate amplitudes. median method relies accurate first-break picking waveform consistency....
The development of DAS technology has brought new opportunities and challenges to the field oil gas resource exploration. first arrival traveltimes, due receivers being located in well DAS-VSP/VSP type data, carry more information from deep underground strata, which offers possibility for building depth domain velocity models using arrivals. This work aims explore capabilities artificial neural networks establish based on VSP traveltimes. We create training dataset by utilizing zero-offset...
Summary Geometry playing a crucial role in the integrity of seismic wave-field, and geometric parameters are therefore considered key image processing resolution. In spite optimization survey, target this case study is affected by rough surface topography poor excitation condition overburden. paper, we present methodology visibility analysis which applied to 2D target-oriented acquisition design for extracting optimal parameters. An work flow based on shot using full-acquisition aperture...
Abstract The Cambrian Longwangmiao Formation in the Sichuan Basin, southwest China, mainly comprising of dolomites, is one most ancient production layer world. Recently, Anyue gas field was discovered Leshan-longnvsi paleo-uplift central and become oldest carbonate rocks a single structural system China. reservoir distributed shoal grain dolomite, which always controlled by sedimentary environment. conventional well correlation facies analysis might result difficulty shoals distribution...
In mountain oil and gas seismic exploration, the deep-hole dynamite source is usually adopted because of undulating terrain. When drilling shothole, engine, bit support equipment as a whole form noise continuous ground vibration, which generates surface waves. this paper, we present an acquisition geometry using source, acquired data processing, pseudo wave extraction method. The pilot field experiment shows that extracted very close to by multi-channel transient method 1-D near-surface...
