... Abstract Hydraulic fracture morphology is an important parameter for fracturing effect evaluation, reservoir simulation and production prediction. It mainly relies on microseismic interpretation to obtain hydraulic fracture morphology, but the presence of ambient noise and irrelevant rupture...

... Abstract The high productivity blended acquisition technique greatly improves the acquisition efficiency. However, this technology also introduces serious interference noise from adjacent sources. An efficient data deblending method based on sparse inversion is used to separate the simultaneous...

... is not accurately detected, the sustained high casing head pressure persists and could lead to undesired outcomes even after the repairs. Here, the high accuracy Sonic-Noise Log (SNL-HPT) was deployed through slickline. Data acquisition process involved both shut-in and flowing modes. The shut-in mode required...

... Abstract In an increasingly complex exploration environment, the acquired seismic data are incomplete and irregular, and field interference often seriously affects the S/N (signal-to-noise ratio) of complex seismic signals. At the same time, weak seismic signals in deep geophysical target...

... Abstract The world largest 3D DAS-VSP survey was completed through the joint OBN and 3D DAS-VSP data acquisition project. The data processing workflow includes deblending, noise removing, first break picking, FWI inversion, velocity modeling building and lease RTM processing. The multi-well 3D...

... have been applied to various reservoir analysis methods. Nevertheless, many of these methods are suboptimal in detecting production trends in different wells due to data artifacts (noise, data scatter and outliers, inadequate SCADA systems, production allocation problems) that obscure unit reservoir...

... surveillance duration can be achieved within 2 hours compared to conventional well sand sampling per well which requires a minimum of 24 hours before sand production rate is determined. ASM sensors are clamped on the well flowline to detect and record the noise vibrations produced by the sand while OSS...

A well-established processing workflow was used to process data that included enhancement of signal-to-noise ratio...
