We present an integrated method for mapping the basement structures of sedimentary basins by combining surface gravity data, seismic imaging, and borehole logging information. The core is a nonlinear inversion algorithm constructing shape depth from data. By using primal-logarithmic barrier method, we impose constraints was imaged interpretation incorporated into as reference model. As result, ...

Abstract In recent years, natural gas hydrate has attracted increasing attention worldwide as a potential alternative energy source due to its attributes of wide distribution, large reserves, and low carbon. Since the acoustic characteristics hydrate‐bearing reservoirs clearly differ from those adjacent formations, an approach, using seismic logging, is one most direct, effective widely used me...

Reykjavik is almost entirely heated by geothermal energy. Yet, recent growth of the city significantly increased heat demand. Past experiences in Iceland's capital region showed that hydraulic stimulation existing wells suited to improve performance and energy supply. However, fluid injection may also trigger felt or even damaging earthquakes, which are concern populated areas pose a significan...

For the purpose of clarifying seismic response characteristics fractured-cavity reservoirs Dengying Formation in central Sichuan Basin, paper first intends to establish three geological models fracture cave based on drilling, logging, and core data Basin. Then, formation reflection is calculated with reference anisotropic Horizontal Transverse Isotropy (HTI) medium. Finally, further research Am...

As software Distributed Shared Memory(DSM) systems become attractive on larger clusters, the focus of attention moves toward improving the reliability of systems. In this paper, we propose a lightweight logging scheme, called remote logging, and a recovery protocol for home-based DSM. Remote logging stores coherence-related data to the volatile memory of a remote node. The logging overhead can ...

stress waves contain useful information about the properties of porous materials; they can be recovered through different non-destructive testing methods such as crosswell, vertical seismic profile, borehole logging as well as sonic tests. in all these methods, it is crucial to assess the effects of frequency on wave attributes including velocity and intrinsic attenuation. the dependency of per...

Logging while drilling (LWD) is a drilling technique which obtains and transmits the logging data during oil/gas drilling operations. Because of the limited available transmission bandwidth of mud channel, how to improve the bandwidth utilization becomes a critical problem in LWD research. In this paper, by discussing the information entropy of real logging data, we find that the original encod...
