By interpreting the full wavefield, waveform inversion has potential to become a key tool interpret seismic data acquired in complex geological settings. However, its application requires low frequencies and large offsets avoid ending up local minimum. This approach been illustrated with marine sets acoustic inversion. Acoustic can also be applied land when acquisition pre‐processing are planned correctly. To demonstrate relevance of this dedicated approach, we invert set down 1.5 Hz 20 km...
ABSTRACT Velocity model building and impedance inversion generally suffer from a lack of intermediate wavenumber content in seismic data. Intermediate wavenumbers may be retrieved directly data sets if enough low frequencies are recorded. Over the past years, improvements acquisition have allowed us to obtain with broader frequency spectrum. To illustrate benefits broadband acquisition, notably recording frequencies, we discuss land acquired Inner Mongolia, China. This set contains 1.5–80...
ABSTRACT Dense, wide‐aperture and broad frequency band acquisition improves seismic imaging potentially allows the use of full waveform inversion for velocity model building. The cost dense acquisitions however limits its applicability. Blended or simultaneous shooting could lead to a good compromise between acquisition, although cross‐talk sweeps may reduce capabilities. Onshore, is achieved with distance separated sweeping because shots are easily when processing focuses on pre‐critical...
Water injection for oil displacement is one of the most effective ways to develop fractured-vuggy carbonate reservoirs. With increase in number rounds water injection, development effect gradually fails. The emergence high-pressure capacity expansion and technology allows increased production from old wells. Although has been implemented practice nearly 10 years reservoirs, its mechanism remains unclear, curve not apparent. In past, evaluating could only be done by measuring...
As the demands of tight-oil Enhanced Oil Recovery (EOR) and controlling anthropogenic carbon emission have become global challenges, Carbon Capture Utilization Sequestration (CCUS) has been recognized as an effective solution to resolve both needs. However, influential factors dioxide (CO2) geological storage in low permeability reservoirs not fully studied. Based on core samples from Huang-3 area Ordos Basin, feasibility CO2 sequestration are analyzed through caprock breakthrough tests a...
Abstract In order to limit the increase in global average temperature 1.5°C, it is necessary reduce carbon dioxide (CO 2 ) emissions by 45% 2030. CO capture, utilization and storage (CCUS) one of effective ways emissions. Geological provides a solution with lowest economic cost fastest effect for reducing This article proposes regional division method based on characteristics low‐permeability reservoirs Yanchang W oilfield China.

The device which utilized exhibited higher transmittance lower resistivity than cell using Furthermore, based demonstrated enhanced charge transport capability optimized contact relative to those employing 2PACz. achieved...
Development of nucleic acids containing unnatural moieties has expanded the scope genetic materials, and modifications nucleobases have been extensively explored found broad applications. However, previous efforts mainly focused on modifying with small molecules, while nucleobase modification macromolecules barely explored. In this work, we first demonstrated construction highly programmable bottlebrush-like DNA structures by enzymatic production modified coupling handles chemical attachment...

Abstract Backbone‐modified nucleic acids are usually more stable enzymatically than their natural counterparts, enabling broad application as potential diagnostic or therapeutic agents. Moreover, the development of with unnatural backbones has expanded pool genetic information carriers and paved way toward synthetic xenobiology. However, synthesizing these molecules remains very challenging due to requirement for harsh reaction conditions low coupling efficiency during traditional...

A low-damage approach to fabricate high-quality W-doped In2O3 (IWO) films as transparent electrodes for semi-transparent perovskite solar cells was developed by the use of a reactive plasma deposition (RPD) equipment. IWO were directly deposited on Spiro-OMeTAD RPD at room temperature. The high O2 flux can be effectively reduce resistance IWO/Spiro-OMeTAD interface, resulting in improved cell performance. maximum efficiency IWO-based 16.5%, comparable that conventional Ag electrode cells....
Normally suppose the seismic reflection incidents vertical to ground in normal exploration area, because obliquity of sub‐surface layer is small, maximum offset limited and refraction LVL, so wave can pass geophone array.
